Revised OR-32 Audio Bag for OrcaBags

April 7, 2016 – 11:37 am

I’ve been playing with a new pre-release version of the Orcabags OR-32 I got from the Orca bags R&D team. I built directly out of my version 1 OR-32 and I must say, I am VERY impressed with the myriad of updates!

The bag retains all of the features I really liked, like bag rigidity, accessibility and quality construction.

The updated bag has addressed some early issues that I had with the OR-32, (even as serviceable and robust as it was) and dealt with ever single issue and adding some nuances and user upgrades along the way!

  1. Main TPU Loops have been moved to the frame – This means no more drooping sides when clipping cables and accessories to the bag.

  2. All small snaps have been converted to Velcro connections.

  3. Rain flap Velcro has also been added in lieu of snaps when rain flap is in use. Finally, the flap has an addition of velcro so that it can roll up into itself and stay shut.

  4. Both zippered side access points have been converted to a larger and more accessible oval opening with extra zipper heads.

  5. Side Removable accessory pouches also lose their snaps in favor of Velcro connections.

  6. Extra Zipper Heads on all four corners allow for more cable management options.

  7. Pull tabs at velcro connections allow for easier opening of bag sides.

  8. At the top front pocket they are two Velcro straps to hold a boom pole / protector. Great addition!

    I also wanted to confirm that CF & SD cards and 1/8” Headphones input are accessible on Sound Devices 688 when mounted properly. I used some zip ties to really lock it in after leveling with the OrcaLift mounts.

Cheers Orcabags on a great revision of a great product!

 


How DPA Has Impacted Our On-set Workflow – Chapter 1 – “On The Boom”

February 25, 2016 – 3:59 pm

As we know, there is no one “perfect” microphone that fits all scenarios. Sound can get pushed out in a wide/tight… sometimes a space is more reverberant than we’d like… or background noise can be an issue. There are different issues that we have to deal with on set and each microphone fits a given need for certain situations.

Previously, we felt our “arsenal” of microphones was adequate and ample. We have mics that we like inside and outside, for use in live spaces, lower sensitivities, looser/tighter frames & importantly, matched sets. Well, we had the chance to add in a full spread of DPA microphones to our list.  We were quite pleased with the additions.

Our pre-DPA load out was as follows:

    • 2x Schoeps CMIT-5U Shotguns
    • 2x Sennheiser MHK-50 Supercardioids
    • 2x Schoeps CMC641Supercardioids w/ GVCs

We’d commonly use the CMIT for exteriors and the MKH-50 for the majority of our interior work. The 641 would come into play in tight closeups, reverberant rooms and as a versatile plant mic. The 641 also got some play with the GVC swivel for a lower profile when we were in situations with tight headroom or walking through doorways on walk-and-talks.

In October, we had to send a Schoeps CMIT5u back to Germany (which takes time) to get it checked out for an occasional ticking sound while using it wirelessly. I ended up buying my first DPA 4017B to use as a temporary replacement. We liked it… a lot.

In December, in addition to our existing DPA 4017B, we received the following:

    • 1x DPA 4017 Shotgun Capsule (for a total of 2)
    • 2x DPA 4018 Supercardioid Capsules
    • 1x DPA B Preamp (for a total of 2)
    • 2x DPA C Preamps

We’ve had the DPA gear mixed in with our pre-existing kit for about 3 months now. We’ve slowly integrated it into our workflow. It can take some time to become confident with microphone choices on the fly in the quick-paced environment that we work in. Over that time, we’ve learned about the DPA microphones and have come to rely them as essential parts of our kit.

Chapter 1 – On The Boom

RF & Humidity

Schoeps microphones sound great. We love the rich sound of the CMC641 up close and we also love the range and punch of a CMIT5u, even from five feet away on an exterior wide. They almost can’t be beat. Schoeps owners love them… until the occasional humidity flutter hits the CMC series. Or the occasional RF “tick” we sometimes experience while running a wireless boom with the CMIT. Now, it doesn’t happen very often, but when it does, you have no choice but to go to another microphone.

In three months, we’ve really enjoyed the clean, crisp sound of our DPAs. We’ve also experienced no RF problems or humidity issues. We are going to keep our ears out as we get into the warmer, wetter months ahead, but we’ve also talked to other DPA users and they tell us that it has not been an issue.

Modularity

Much like the Schoeps CMC series, the DPA line is totally modular. You can switch from a 4017 capsule to a 4018 using the same preamp in the time that it takes you to unscrew and re-screw in the desired capsule. That means you can switch from a shotgun to a supercardioid using the same preamp. 

Sound & Reach

The DPA 4017 shotgun has a fantastic reach and a great, full sound. It compares very similarly to a CMIT in an exterior wide. The DPA is a great microphone, especially when you consider the lower price, the modularity and RF immunity when compared to the CMIT.

The DPA 4018 supercardioid has become one of my favorite microphones for interior use on the boom. It fills a gap I wasn’t really aware that I had in my microphone package. Typically we’d use the MKH50 for medium work and go to a 641 for closeup work (when we could). Now we use the 4018 for medium and closeup work to great result.

In certain situations, the 4018’s reach was not quite as deep as that of our MHK50, but the 4018C gives us a lower profile option for walk-and-talks through doorways that used to demand the CMC641 with the GVC swivel. When pushed to a medium shot, the 4018 just packs more punch than the 41 and with a smaller profile than the MKH50.

Reverberant Spaces

Shooting a scene in a reflective bathroom on a medium/tight lens? The 4018 delivers a great sound while reducing some of the effects of the reverberant space similar to the 641, but with more “bite” when at a higher headroom.

Frequency Response

As DPA is very exacting to get an almost identical flat frequency responses from all their different microphones, including lavalieres. Because of this, the DPA products we’ve tested seem to mix exceptionally well together.

B Preamp vs C Preamp

The main differences between the two preamps are size and the filter options. The B is the larger of the two and has both a low frequency roll-off filter and a high boost filter switch built-in. The C preamp is about 2 ½ times smaller in length than the B preamp. The B preamp weighs just a bit more than the C, but not by much: 1.48g vs 1.45g.

In-Country Service Center

If you have a DPA that needs service or repair, there is a service center in the USA. Telephone support is also available. Sennheiser also offers a USA service center and support. Schoeps offers top-notch USA support through Redding Audio, but any microphone service must be sent to Germany.

DPA Microphones, 1500 Kansas Ave. Suite 3A, Longmont, CO 80501

303-485-1025

Windscreens

We’d like to see a slightly denser foam option for both the 4017 & 4018. The current offerings are not quite as wind-resistant as the windscreens that come with our Schoeps & Sennheiser microphones. That said, this is only noticeable when doing quick interior cueing and is a minor issue.

Storage

The 4017B comes with a nice case that can hold other DPA accessories too.

Price points (as of 2/12/16):

    • $2199.00 Schoeps CMIT-5U
    • $1199.95 Sennheiser MHK-50
    • $1622.00 Schoeps CMC641
    • $1799.95 DPA 4017B Shotgun Capsule with B Preamp
    • $1709.95 DPA 4018C Supercardioid Capsule with C Preamp

Prices are all in the same ballpark with the CMIT on the high end and the MKH50 on the low end. Many will find the 4017 to be a bargain at $400 less than the CMIT. I think the reach on the 4018 is well worth the additional $90 when compared to the CMC641.

In conclusion:

We’re extremely happy with the DPA offerings. They have definitely helped to make our work sound better. We even have a new “go-to” microphone for medium and close-up interiors, the 4018. Kudos DPA!

Lectrosonics Venue vs. Venue 2 Breakdown – Part 1

December 16, 2015 – 12:33 pm

v1

I’ve recently had the pleasure of using the new Lectrosonics Venue 2. It’s such a huge improvement over the original Venue; something our industry already considers the proven modular workhorse. With new features such as wide-band blocks, IQ filtering, lowered noise floor, Wireless Designer with built-in frequency coordination and—one of my favorite features—menu-driven antenna power toggling, you can be sure to see the Venue 2 on sound mixer’s carts all over the world soon enough!

What the new and old Venues have in common:

The Venue and Venue 2 share many core similarities. Each can handle six wireless modules which can be installed without tools. Both have a built-in RF multi-coupler with loop-thru output to gang multiple units together through a common pair of antennas. Phantom power is available to run remote powered antennas. They are also both available in Wideband Low (470 – 691 MHz) and Wideband Mid (537 – 768 MHz). For the most part, every feature from the Venue has been carried over and/or improved in the new Venue 2.

  • Front Face

The front face on the new V2 is a flush surface with membrane buttons, a welcome change. It also sports a new non-glare flush-mount LCD that has brightness options and can display more information. The selector dial is now a larger wheel. New additions to the face include: Alert indicators, an IR port (for programming newer style transmitters), a USB connectivity port and a recessed reset switch. The headphone knob is now a push to open/close knob. Also of note: There are two rubber caps on either side of the face that allow BNCs to be rerouted from the back to the front of the venue.

  • Rear Panel

The V2 rear panel has all of the same elements of the original V1 with a singular and powerful addition: the ethernet port. The BNC ports have been rearranged into an over/under rather the the V1’s side by side layout.

  • Top

Existing V1 users will be at home with the design of the V2. Modules are loaded in the same way and locked into place with clips, just like the V1.

  • VRT vs VRT2 – Wideband

The new VRT2s are now wide band. They allow tuning between three consecutive blocks with 3072 tunable frequencies in each module called Bands. A1, covering blocks 470, 19 and 20 (470.100 – 537.575 MHz), B1, covering blocks 21, 22 and 23, (537.600 – 614.375 MHz), C1, covering blocks 24, 25 and 26 (614.400 – 691.175 MHz). Please note: older VRTs and VRSs are not compatible with the new V2.

  • IQ Filtering

Basically, IQ filter means Intelligent Q. The filter dynamically adjusts according to received signal strength. Let’s say you are in a hi RF environment . With Venue, you would run a risk of front end overload setting your transmitters to 250 mW at close range. IQ filtering sharpens the Q of the filter and lowers sensitivity if the signal is strong. This reduces interference and allows tighter spacing. If the talent walks away, the sensitivity increases and the Q is lowered to capture more RF. Impossible to overload and automatically adaptive. At its lowest Q it’s like a VRT. At its highest Q, it’s like a 411 on steroids. Additionally, the tracking changes with the frequency – more resolution – LOTS MORE– Gordon Moore, President of Lectrosonics

  • Phase Switching & Noise Floor Reduction

Considerable time was spent in engineering on the diversity circuit and algorithms for the Venue 2. First, how often the phase switching takes place was reduced. In the older systems, this switching is more aggressive, meaning that even with fairly strong signals, the phase of the 2nd antenna can still tend to switch. With the Venue 2, this switching is minimized to when it is absolutely needed, i.e. the signal drops by a lot and/or the noise is increasing. Because of this, there are fewer corrections needed to keep this switching out of the audio.

Then, a significant amount of tuning by ear was done to the design of the hardware and software filters and timing elements. Even though the resulting numbers appear to be better only by a small amount (up to a 1.4% reduction in distortion at 250 Hz, with 45 kHz of deviation, for instance), the improvement in subjective sound quality is more significant. Of course, users will have to judge for themselves if they can hear these improvements.“ Karl Winkler, Vice President of Sales at Lectrosonics

  • Spectrum Scan

The Spectrum Scan operates as before. It’s scan speed has been improved quite a bit, especially considering it scans three times more of the spectrum with the new wide-band VRT2s.

  • Smart Tune

The SmartTune process is like that in V1. It provides a step-by-step way to set frequencies based on real world conditions. It works well for up to six channels, but any more than that will probably take longer than most people have the patience for.

  • New LCD

The new screen is 50% larger and has a much higher resolution, allowing for more information to be displayed. It is also now flush with the face of the V2. It has four settings for brightness control and sports a non-glare screen. 

  • Alert Indicators

The V2 now will now report when an antenna short is detected by blinking above the hazard icon and turn off power to antennas automatically. The bi-directional arrows next to the hazard symbol let you know when the V2 is connected to a computer source through the ethernet or USB connector running Wireless Designer.

  • Wireless Designer: Venue Control, Frequency Scanner & Coordination

Wireless Designer is a great suite of tools that offers direct control of your V2’s functions and marries in a built-in full spectrum frequency scanner that has easy exporting ability to it’s frequency coordination program. I will explore the Wireless Designer tools in more detail in the upcoming “Road Test”.

http://www.lectrosonics.com/Support/Wireless-Designer/wireless-designer.html

  • Front USB Access

Windows users can easily direct-connect to the V2 via Wireless Designer with standard USB “B” cable. Lectrosonics is currently working on an update to allow OSX users to use the USB connector in the front. The update should be entering a beta test period soon and should be available to Mac users in the near future.

  • Ethernet Enabled

You can connect to the V2 with both Mac and PCs via Wireless Designer. Your V2 must be wired into a router so that it is assigned it’s own I.P. address. As mentioned above, this is only way, currently, to connect a Mac to the V2. 

  • Talkback

Talkback is a brand new feature built into the V2. It sets up a module as a “com” channel so the person using a HH transmitter can have a direct line to the crew or production staff by depressing the button on the HH. It might come in handy for a “Voice of God” setup.

  • IR Transmitter Control

With newer transmitters that allow it, such as the LT, you can have the V2 program your settings by holding up your transmitter within a couple of feet from the IR Port. You can choose to send frequencies only, or send all settings for the transmitter.

  • Menu-based Antenna Power Toggling

Finally, we can turn on and off phantom power without having to pull the V1 out the rack after disconnecting all cables and then using a screw driver to open the unit up and then reseting the jumper pins and then reversing the process! Now, it is as simple as a toggled setting in the V2 menu, or from a screen in Wireless Designer.

  • Walk Test Recorder

Walk Test Recorder is a utility built into Wireless Designer that records the signal strength of a transmitter during a walk test on a scrolling display. You have the option of recording the audio to the computer by using the included ¼” to 1/8” adapter. The audio will sync up to scrolling display on playback so you can visually see signal strength as it references any audio problems.

  • Pricing

Venue: $1,499.00 / VRT Module: $550

Total Venue & 6 VRT modules: $4799

Venue 2: $2375 / VRT2 Module: $679

Total Venue 2 & 6 VRT2 modules: $6499

Cinela Piano vs Rycote WS 4

April 24, 2015 – 12:02 am

20150423_003745So the Cinela Piano is currently the most talked about item when it comes to full microphone windscreens. And most often it get compared to the latest Rycote offering, the Cyclone.

But why not compare it to an old industry standard? The Piano is very nice, but is it nicer than the tried-and-true Rycote WS 4. Specifically in our case; when used with a Schoeps CMIT-5U.

Both offer modular wind resistance in varying degrees depending on the atmospheric conditions. Most say the Piano provides more wind resistance with a clearer sound. We haven’t tried it in hurricane-like conditions yet, but we have used it on set in tandem with a second boom mounted with the Rycote WS 4 in strong winds.

So, is it better? The answer is yes… and no. Let’s break it down.

Wind Noise Mitigation

Both do their jobs very well. In a rough surging wind, we compared the Rycote Windjammer to the long hair Cinela PIA-FUR-POLY-H. We engaged the hi-boost on our CMITs and both sounded very good. In the end, the Piano took the gusts a bit better than the Rycote.

Edge: Cinela Piano

Skin Options

Having the right skins for your windscreen can make or break how well your windscreen works.

Now, the Rycote has three different options:

  1. Hi Wind Cover (the fleece cover)
  2. Windjammer(a.k.a the “Deadcat”)
  3. Duck (for rain protection)

The Cinela offers more skins than the WS-4. Six different ones, in fact. I’ve only auditioned the Neoprene and Pia-FUR-POLY-H, but I have the PIA-FUR-POLY-S and the PIA-KELLY on order. (Special thanks to Justin @ Pro-Sound for sending me this list of skins!):

  1. PIA-FUR-SP: Short Pile fur (classic range): lowest volume, clearest sound, second step of wind protection over the main fabric
  2. PIA-FUR-POLY-S: Long pile Polyester fur (new range): bigger volume, no inner lining, clearest sound as the PIA-FUR-SP, better wind protection than PIA-FUR-SP
  3. PIA-FUR-POLY-H: Long pile Polyester fur (new range): bigger volume, standard inner lining, sound begins to be affected (low and high range) but improved wind protection (like the “old” PIA-FUR-LP)
  4. PIA-FUR-POLY-BK: same as version “H”, but with reinforced lining: Sound is audibly affected, but wind protection is really important.
  5. PIA-KELLY rain cover
  6. Neoprene Cover (Comes included with the Piano along with one other cover of your choice).

Edge: Cinela Piano

Handling Noise Mitigation

During the testing, we didn’t have any issues with handling noise, but I also have two good operators. My intuition and from what I have heard: I would give the edge to Cinela. I will do some testing tomorrow to confirm.

Edge: Likely Cinela Piano

Stay on Target

The Rycote is a straight tube with rounded ends. The lends itself to finding the sweet spot like an arrow (assuming you point it in the right direction to begin with, right?). This can be critical in situations like walk-and-talks.

The Cinela’s fatter blimp shape doesn’t give you that immediate right-on-target feeling, especially on the end of a long pole. Also, the bottom of the Piano is black and pulls in the light, making it harder to see (especially at night) which makes it a bit harder to judge it’s depth of field.

Edge: Rycote WS 4

Weight and Size

The Rycote WS 4 weighs a bit more. It is longer, but thinner than the Cinela.

The Piano is lighter… but at the same time, it is bulkier; having a rounded shape as opposed to the straight lines of the WS 4. That being said, it feels like it is more aerodynamic, but conversely might be prone to throw a shadow in frame before the WS 4 in certain situations.

Edge: Tie, but leaning towards the Cinela.

Microphone Accessibility

To access the microphone in the WS 4:

  1. pull of the skin (if there is one on)
  2. twist off the end cap
  3. twist two thumb screws
  4. slide out the mic mount
  5. Adjust settings while CMIT is in the lyres
  6. repeat in reverse to reset the mount

To access the microphone in the Piano:

  1. pull off the skin
  2. pull apart the cage (there are pins at four points)
  3. use access hole on suspension to engage/disengage filters.
  4. Rinse and Repeat in reverse order to rebuild.

Edge: Cinela Piano by a nose!

Versatility:

 

The Cinela’s suspension are microphone specific. You can get other suspensions if you need. On the other hand, the Rycote lyre system is a bit more versatile allowing for different mics to fit in the same suspension. I think the Cinela suspension is a bit better at isolation and that is the trade off.

Edge: Rycote WS 4 is more versatile, but with a trade off in handling isolation.

Cost:

To compare apples/oranges, I’ll compare the costs with each kit with two skins.

Now, you can get a Rycote WS 4 with a Windjammer and a Hi Wind Cover for a little over $700 from the usual suspects.

The Cinela Piano comes with the Neoprene Cover, a skin of your choice and it comes with a nice zippered case. List price is around $835, but the prices aren’t fixed like some of our other toys. Make sure you shop around and ask for a best quote price. I was able to find it for a very similar price to the Rycote. I won’t tell you my price, but I got mine at very good deal from Trew Audio Atlanta. Ask for Bryan and tell him I sent you. 😉

Edge: Your negotiating skills!

Conclusion

The Rycote and Cinela are both great tools with pluses and minuses. If extreme wind protection is needed, go with the Cinela. If you need to access your microphone to use it in other mounts and need to do it quickly and still have exceptional wind performance, the Rycote is your blimp!

Here are some initial things I’d like to see in a future Cinela Piano Revision:

  1. Engineer a way to open the shell quicker and easier. Also, use connectors that can’t get lost. In the meantime, please include extra grommets and bungee straps just in case!
  2. I’d also like to see the Hi Poly’s Colors reversed so the bottom is grey and the sides are black. It would help with depth of field. And black sides might help out with reflections and such.

A Zaxcom Newcomer’s Look at the TRX742.5 Plug-on Transmitter

April 16, 2014 – 3:03 pm

Okay, first off. I have never owned a single piece of Zaxcom gear. This is my first look at integrating Zaxcom into my Sound Devices / Lectrosonics “heavy” kit. So, this review will be written from the perspective of a Zaxcom newbie.  

Why the TRX742.5? Our team really wanted to find a wireless way to quickly switch from our analog microphones to the digital AES42 powered Schoeps Super-CMIT (preserving both channels of audio from the Super-CMIT) while recording to a Sound Devices 788t. The Zaxcom TRX742 series (in our case, coupled with a Zaxcom QRX200 Receiver) is the only single solution product on the market to allow a boom operator to go wireless with a Schoeps Super-CMIT 2U while transmitting both the DSP(Digital Signal Processed) and non-DSP tracks independently and discreetly. Our current analog wireless system consists of a Sound Devices MM-1 Preamp, a Lectrosonics SMQV Transmitter and a Lectrosonics R1a IFB for talkback. The kit is great for a wireless analog boom, but it would not work for the SuperCMIT… it lacks two channels, AES42 power and Digital transmission (or Digital to Analog conversion). That being said, much of this review will be like comparing apples to oranges, as the 742.5 crosses the boundaries compared to the other tools in our existing kit with it’s built-in multiple features.

Sound Quality We did a test between two Schoeps CMIT-5Us. One with a TRX742.5 and the other with a Lectrosonics HM. To my ear, they both sounded very good. The frequency response on the low end was very subtlety different between the two, but negligible. When we tested the SuperCMIT, we found both channels to also sound excellent on the TRX742.5’s two channel feed.

Battery Life We powered the 742.5 with three Energizer Ultimate Lithium batteries. Run Times @ 125 mW:

  • SuperCMIT Stereo mode w/ AES42 cone: 3h 8m
  • SuperCMIT Mono mode w/ AES42 cone: 3h 20m
  • CMIT-5U Mono mode w/ Analog cone & Phantom Power: 5h 58m

Note: There is a “Power roll” setting that drops the power transmission level down when you are not rolling. This can be set to be triggered by one of two events: “Deva Trigger” via Zaxnet or “Record Trigger” via the REC button on the transmitter. Without a Deva, I couldn’t use the “Deva Trigger” function.

Neverclip / Limiter In analog mode, the Neverclip limiter is impressive. I whispered… it sounds great. I YELLED, it still sounds great. Good stuff! Of note, there is no digital limiter available when using AES42 mode with a digital microphone. It will clip if the maximum decibel level is hit.

Howy at Zaxcom says “There is no NeverClip in the digital mode. You can turn off the compressor (DYNAMICS page) if you want, but I would keep it on because it can really get you out of a jam if someone starts yelling and in almost all cases it makes the audio just sound better on average.” 

Interchangeable Cones for Modern Microphones The TRX742.5 has multiple cones for use with different microphones. There are four different styles: Analog, Stereo, AES & AES42. The cones come on/off with two screws. The cones I have for testing (Analog & AES42) look very much the same. Upon closer inspection, there is a hand-written note in permanent marker on the inside of each cone which designates it’s type. As with many modern audio devices, the TRX742.5 does not support T Powered Microphones.

Timecode Integration w/ Non-Zaxcom Gear The 742.5 can be set to accept mic-level timecode via it’s audio input XLR while using the Analog Cone. You need to set the TC Input in the Extended menu to Audio Input. (To enter the extended menu, turn the unit off, hold the menu button down while turning it back on.) If you need to jam it via your 788t or a Denecke SB box, you will need to pad the signal down by 20 dB. One downside for non-ZaxNet users of the TRX742.5 while using the AES42 cone, you can not jam timecode via the audio input as the TC signal is analog signal). You must use ZaxNet enabled device to jam. One option is to add an Zaxcom IFB transmitter to the kit. This is able to pipe timecode to the 742.5 from a 788t or other style timecode box (such as a Denecke SB-T). This would also add the benefit of constantly refreshing the timecode between devices. I tested an IFB200, and with some minor setup was able to get the device to jam via Zaxnet.

Wideband Frequency, New Frequency Modulation & Encrypted Audio Transmission One of the big differences between the 742 and the 742.5 version of the TRX is that the newer version now can operate with a much greater frequency flexibility, a.k.a. Wideband, between 512 & 698 MHz. (Blocks 20 to 26 on the Lectrosonics charts). Zaxcom says their new software modulation increases the range of their transmitters. I can’t personally compare it with the older version, but I have heard from other sources that it is better. The Zaxcom signal is also encrypted from point to point between the transmitter and the receiver.

Backup Recording The 742.5 has timecode stamped back-up recording abilities. It records to a format called MARF (Mobile Audio Recording Format) which is considered as a highly reliable format. Even if power is lost, the recording will remain intact up to the point of the power loss. It does involve the need for conversion to use with some programs. It will record both channels of a stereo microphone or an AES42 powered microphone.

QRX200 integration w/ Lectrosonics Venue and Antenna Cables Antenna integration worked very well. We daisy chained the antenna leads from the QRX200 into the Lectrosonics Venue with some custom SMA to BNC cables and we were able to use our existing Lectrosonics ALP600 antenna system.

Transmission Distance We compared the digital TRX742.5 (@125 mW) with the HM (@100mW) on some range tests around the studio here. We found them to be similar with the HM giving a little better range. While the HM dropped out and was spotty… the TRX742.5 signal was gone completely. While both signals were unusable at that point, the TRX does have the backup recording option. It could certainly save the day in certain situations. This test was in and outside of the studios and was not line of sight. We also did a range walk test on the TRX742.5 between the whip antennas and the Venue/ALPs. There was definitely an increase in range using the sharkfins by about 50 to 60 feet. This also was not a clean line of sight test. The cart remained in the studio and my boom operator went outside until signal dropped out.

Zaxnet ZaxNet allows allows you to control levels on transmitters, passes timecode between devices automatically and other helpful and intelligent functions. Without Zaxnet, I was unable to use these functions. However, when I added a Zaxcom IFB200 into the workflow, I was able to pass timecode and it also allowed me to remotely control the gain on the TRX742.5.

Build Quality & Form Factor The 742.5 is about ¼ to 1/3 larger than a HM, which makes sense as it has a much larger feature set. It is about 2/3 enclosed in a decent thickness metal. The battery enclosure is plastic with a flip up lid. It is held closed by three small magnets. Two screws hold the interchangeable cones. The cones each have a standard Switchcraft style lever disconnect that is protected on three sides by the metal of the cone. An SMA antenna is mounted on the bottom. A control panel is mounted on the side with membrane style switches with a lit LED display panel. On the side above the control panel is an exposed opening for the microSD memory card.

My Thoughts Honestly, the 742.5 feels solidly built. If there was a weakness, the battery door could be it.  I have heard of reports that some TRX742 users tape or rubber band the door shut to be safe on scenes with quick moves to keep the door from opening up. That being said, Zaxcom has added a third magnet to help hold the door shut on the newer TRX742.5. According to Glenn at Zaxcom, no 742 series plug-ons have been sent in to have their battery doors repaired because of any problems with the plastic. The power switch is small, but it is protected by the battery door. The exposed memory card slot could be an issue to introduce dust or moisture if no card is in place, so I think it would be best to keep a card in the slot when in use, even if not recording.

I would have liked to see the next generation of the 742 fully enclosed in metal with a bottom-mounted battery door that also enclosed the power switch and the memory card, but according to Colleen: “You can’t do an all metal body. The reason for the nylon composite is that’s where the ZaxNet antennas are located – you can’t transmit or receive through metal!” So there you go.

Prices

  • $1995 for the Zaxcom TRX742.5 with Analog Cone
  • $200 for each Additional Cone (AES42 was the additional cone for us)
  • $2500 for the Zaxcom QRX200 Wideband Receiver
  • $40 Two SMA to BNC 50ohm Antenna Cables (To link TRX to Venue)
  • $50 Balanced Stereo Breakout Cable TA5F to XLR3M

$4785 TOTAL (Add an additional $1350 if you want to add a IFB200 for Zaxnet / Timecode)

Conclusion: If you want to go wireless with a Super-CMIT, there isn’t any option simpler than with a TRX742.5 paired with a Zaxcom receiver. That being said, there are some issues worth noting:

  • Lack of a limiter with an AES42 powered microphone
  • Need of a Zaxnet transmitter/IFB to jam timecode in AES42 mode
  • Short, but manageable battery life
  • Price is steep… but considering all the things it does, it certainly may be economical when it is used to it’s full potential.

The upside for wireless SuperCMIT users is that you get both DSP & non-DSP channels discreetly and a rock solid backup recording with timecode (if using ZaxNet) via a great sounding pair of signals. Also, you get the security of a wideband frequency range which lets you know you can find a clear frequency just about anywhere. Zaxcom has packed quite a bit of power into a very small form factor, especially considering how much gear would be needed to accomplish the same feat with the current offering of the competition’s gear. Kudos to Zaxcom for bring something truly unique to the market.

Special Thanks: to Colleen & Glenn at Zaxcom for making these products available for me to test and to Howy at Zaxcom for helping me through some technical hurdles on the gear.

In Plain Sight… The Pen Mic!

November 15, 2013 – 6:51 pm

On my last show, I was having some problems with body mics and scratchy police officer wardrobe.

After trying different ways to mic up the cast with hidden techniques that were not 100%, I though I’d venture into the realm of the pen mic.

Now, I’m not the first person to use the idea… it’s just my first foray and I thought I’d share my results. With the right pen, the process is very quick!

Shopping:

The first thing I did was go pen shopping! My criteria:

  • Space for a Sanken COS-11 to travel up pen
  • Room for a Windscreen at top
  • No logo visible when placed in a pocket
  • Black Pen Color to match Sanken.

While shopping, I found the Foray Gelio Super Comfort Grip (Retractable Gel Pen, 0.7 Mm, Medium Point, Black Barrel, Black Ink) and thought it looked like a good candidate.

The Process

Foray Gelio

First I unscrewed  the tip and then removed the ink & stylus. Then, using a pliers, I crushed the plunger allowing it’s removal without damaging the outer tube of the pen. The plunger, ink stylus and tip can go into the bin.

I then did a test with a COS-11 to see if it would fit up through the tube… Sure enough, it fit! Then for the windscreen test… it fit with almost no space to spare. Perfect!

Now to button things up and secure the mic on both sides of the pen, I took some small pieces of Joe’s Sticky Stuff (aka Snot Tape) and stuffed some evenly around the head of the mic (while the windscreen is off) while trying to keep the head centered. I used a Tweeker tool to careful push the Joe’s and mic head into place. I then reapplied the windscreen and pushed it into what looked like a decent position. Finally I put a plug of Joe’s into the bottom of the pen to hold the cable in place.

Joe’s Sticky Stuff is removable. If you were looking for a more permanent installation, I think Sugru would be a great choice!

Who to use it on?

This mic is great for cast with pockets on the shirt. Cops, scientists, etc… You will need to get together with the wardrobe department to have them cut a hole behind the pocket for routing of the wire to the pack.

Here is the result! Enjoy!


MuxLab 500052-Pro-BNC Video/Audio Balun

July 1, 2013 – 8:18 pm

A couple of weeks ago, I upgraded my trusty lightweight MuxLab Balun System to a new beefier version, the 50052-Pro-BNC.

What is a Balun and what is it used for?

Balun is short for” BALanced to UNbalanced”.  What is does is passively take in separate signals of audio and standard defintion video and pass them across a single CAT5 Cable. A second Balun on the other side converts the signals back into separate feeds. They are commonly used by cart based mixers to save on setup time by reducing the amount of cable runs. Plus, Cat5 is very inexpensive compared to BNC or XLR. They do require a down-converter for each feed if you are shooting in HD. The Balun are unidirectional, meaning I can send audio in one direction and receive video on the other.

Up until now, I used two MuxLab 500012 to send up to two audio feeds and receive up to two video feeds. They use non-locking RCA connectors, which means you have to convert XLR and BNC to RCA. Also, as it doesn’t lock, there is the chance of coming loose. The 500012 is very lightweight with a plastic case. Over the past four years of use, I’ve broken two.

Why the 500052-Pro-BNC?

  • Three Cameras

I’ve been shooting a show that at least once a week is shooting three cameras and it can be a struggle to be sure of the frames of the widest shot so I can direct my BoomOp. Previously, with the 500012 I could only view two cameras. The ability to see three cameras is a big plus!

  • Locking & Color-coded BNC Connectors

No more connections to slip out or getting the cables confused with the new balun! It also allows you to use either standard Ethernet or lockable Ethercon for your cable connection between the two baluns.

  • Rigid Metal Case and Cables

It weighs more than twice as much as the 500012, but it is MUCH more solidly built. A metal case, plus heavyweight BNC cables and strong connectors should equal a much longer lifespan than my original balun.

Setup from the 500012 to the 500052

Setup is identical as with my older balun, but it eliminates any need for BNC to RCA adapters.

You will still need a XLR to RCA adapter (which is my biggest beef with the new balun) for the audio connection.

Summing up the Pros:

  1. Three Cameras over a single Cat5 Cable
  2. Locking Video Connectors and Robust Cables
  3. Metal Case that is much stronger
  4. Can connect the balun by either ethernet or the more robust Neutricon ethercon connector

…and the Cons:

  1. Weighs more and is larger in size
  2. Doesn’t have a locking audio connector

Overall, the new 500052-PRO-BNC balun system offers more pros over cons for the work I am doing and hopefully will remain on my cart… until they release a version with locking XLR connectors!

Schoeps CMR – Microphone amplifier for bodypack transmitters

June 11, 2013 – 9:33 am

I recently got a Schoeps CMR. It is a single cable solution for connecting a bodypack to a Schoeps MK series capsule. [singlepic id=43 w=320 h=240 float=]

I’d like to start off by saying that if you love the sound of the Schoeps Modular MK series capsules as much as I do, and also use them for your primary plant microphones (in cars, on desks, etc.) you will LOVE what this product does! [singlepic id=42 w=320 h=240 float=]

There were two ways (before the CMR) that we would use the Schoeps as a plant with the following chain of gear:

Plug-on Transmitter:  [singlepic id=41 w=320 h=240 float=]

  • MK41 Capsule > GVC Swivel > Colette Cable > CMC6U Power-supply > Plug-on Transmitter

A fairly straight forward process and fairly simple chain of five pieces.

Bodypack Transmitter [singlepic id=30 w=320 h=240 float=]

  • MK41 Capsule > GVC Swivel > Colette Cable > CMC6U Power-supply > Denecke P48 Box > XLR to TA-5 Cable > Lectrosonics SMV Transmitter

This works, but it get’s more complicated because of the need to introduce phantom power to the mic.  The chain is eight pieces long.

Then you add paper tape & Joe’s Sticky Stuff (don’t have some? GET IT! Miracle product for plants).

As you can imagine, that can be a lot of different bits to grab, sometimes on a moments notice.

With the Schoeps CMR and the Bodypack Transmitter: [singlepic id=32 w=320 h=240 float=]

  • MK41 Capsule > GVC Swivel > CMR Cable > Lectrosonics Bodypack.

This cuts the gack in half for bodypacks with a chain of four (or three if you prefer not to use the GVC Swivel). [singlepic id=33 w=320 h=240 float=]

How does it work? Are there tiny German unicorns on a miniature hamster wheel stirring up the phantom juices to make this amazing product work?

No, but that does paint a nice picture! (Bonus points for whoever actually PAINTS this picture, I’ll attach it to the blog.)

According to the manufacturer about the CMR:

  • low power consumption: only about 1/20 to 1/48 that of a phantom-powered microphone

So, it seems they have found a way to use the small current that the Lectrosonics bodypacks output (that can also power a Sanken CUB-01 for example) and use it to power the mk41 capsule.

The Downside?

Are there any downfalls? Well, like all things, the Schoeps name does not come cheap. I’ve seen it retail for between $659 and $770. It may sound like a lot to pay, but when you consider you don’t need a expensive CMC6 to power the capsule when used as a plant, it is a pretty good deal and greatly simplifies a way to get that sweet Schoeps sound!

The CMR will NOT work with the CUT1, but does work with the DZC- pad and GVC swivel.

It will also not work with Zaxcom Transmitters.

Also, it is a little bit bigger at the connection to the capsule than a Colette, but considering everything in the chain that it eliminates, this is negligible. [singlepic id=36 w=320 h=240 float=]

Conclusion:

That being said, I’ve already put it into play on set. The CMR worked like a charm. I’m sold!

[singlepic id=44 w=320 h=240 float=]

Notes:

Some information about the CMR I found at Posthorn:

** For Sennheiser SK50 transmitters, the CMR must be ordered with the termination installed by Schoeps. It is only available with a 2 meter cable. We do recommend that all terminations are installed by Schoeps. Schoeps has confirmed compatibility with current and legacy Lectrosonics (TA5F) models, Audio Ltd. and Sennheiser SK 50. Other connector terminations available as a special order – exact wireless brand and model info is required. The Schoeps CMR will NOT work with known Zaxcom transmitters or the Sennheiser EW Series. The CMR also will NOT work with Colette Active accessories (e.g. CUT1, KC 5g) or the BLM 03 Cg. A DZC- pad or GVC swivel are the exceptions and can be used.

UPDATE (Sept 10, 2014):

I’ve added a second CMR to my collection. I LOVE them!

Also, a wiring guide from Lectrosonics has come to my attention.
