Wireless Mics
Not just for RF any more!
Breaking new ground with features that will improve the work flow of acquiring, storing and distributing location audio while opening up a new territory of
creative options for every post editor.

Zaxcom sold the first broadcast quality all-digital wireless mic system in 2004. Since
then, Zaxcom’s digital wireless engineering marvels has catapulted them to the top of the list for reliably clean and superior sounding wireless microphone systems. TRX-900 Fact Sheet
Three primary problems with ordinary wireless microphones:
- Come June 2009, when all VHF channels as well as the 700MHz band become off- limits, and the FCC auctioning off the RF spectrum between TV channels (known as “white space” which we now use for wireless microphones), reliably clean RF channels are getting harder to find.
- If you travel with your wireless, a set that works in D.C can not be relied on to work in N.Y , Chicago, or L.A because the channels used for
television in each market may be different.
- Traditionally, if your video project has more than two mic wearers on camera, you either have to mix them down to two camera tracks, split
tracks between multiple cameras, or record double system to a separate multitrack audio recorder.
Never Mind
First of all, because the Zaxcom system is a digital transmission, if you get any audio at
all, it will sound pristine. No noise ups, zips, fips, pops, or clicks. If you don’t put it in, you won’t hear it come out. If there is enough interference on the channel
to desensitize the receiver to the point it cannot decode the bits, the receiver simply mutes.
Now for the good stuff!
The new, smaller, more power efficient TRX digital wireless transmitters can optionally record digital audio, right inside the transmitter. Now,
every mic can record an iso track of itself. Up to 12 hours of file based, 24bit /48kHz digital audio on a single mini-SD card with time code! Whether you use the RF as a primary or
backup, you will have clean iso tracks of each mic. Recording can be either continuous or remotely controlled by either time code start/stop (as in record run), or manually.
Editors - Get ready
Even now, camera crews are starting to deliver video files from camera disks. Now, sound files can be delivered as well.
Move the sound files from the cards to your computer, run them through the Zax-Convert program to output them as SMPTE time code stamped Broadcast WAV files or MP3 files in your
choice of bit & sample rates. Now these audio files will fall into your editing system time line in sync with video. Now you can mix, EQ, mute, and process each mic individually
or the on-set audio mixer’s output prior to transmission to the camera. You can also email the MP3 files for transcription.
Stereo Camera Link & Transcription Recording
When used with the optional STA-100
Stereo Input Adapter, the TRX-900 can transmit two line level audio channels to a camera or anywhere else & simultaneously record them in the transmitter for backup with time code from the camera or the internal generator. In addition to converting these recording files to WAV for editing, they can also be converted to MP3 files for transcription. Printable STA-100 Brochure
Go Live with the built-in IFB Receiver!
That’s correct, the TRX-900 & TRX 992 are transceivers! Now you can get the best damn sounding wireless transmitter plus an IFB receiver in one small integrated belt pack. Plug your earpiece right into the transmitter. What on camera personality wouldn’t love that?
Time Code & Audio Return
Two additional transmitter models send time
code, IFB /return audio, and remote control signals back to the TRX transceivers. The IFB-100 can be mounted on a camera, in a mixer bag, in a studio, or anywhere else. It sends audio
(camera confidence, IFB, etc) and time code back to TRX transceivers. The IFB-100 can remotely control recording record start /stop plus other transmitter functions such as mic input
gain and more. Transceivers can be set up into groups for reception of audio and control signals
As a stand-alone recorder or recording transmitter, time code can be jammed
directly into a TRX-900, 992 or ZFR-100. The internal generator is accurate to 1 frame in 5 hours.
Hand Held Mic /Voice Overs
Two
options are available if a hand held mic is preferred. The TRX-700 MMT is a plug-on Mic Mounted “Cube” Transmitter that will supply 48V phantom power on its XLR connector.
Simply plug in any dynamic or condenser mic and go. The TRX-800 Hand Held Transmitter utilizes a standard or modified Shure mic head and records as well.
Voice Over Artists will
really appreciate that NO OTHER EQUIPMENT is required to record a high quality track other than a TRX-800 or ZFR-800.
Roaming Announcers, Mic Booms, Sideline EFX,
You’ll love the TRX-992. With a 48V Phantom powered
balanced XLR mic /line input, optional 250mW output power, and Return Audio w/ beefed up headphone amp, and recording as standard. And the headphone amp can mix the input with the
return channel or select one or the other.
Recording only version
Variations on the mini-beltpack TRX-900 and the Hand Held TRX-800 transceivers are
the ZFR-100 & ZFR-800
one or two channel* digital audio recorders (no transmitter). The ZFR-100 has audio & TC inputs* with internal or external DC power*. Both units can receive wireless TC & audio from the IFB-800, and are remote controllable.
*Requires STA-100 module. Single channel recording w/ internal power otherwise.
