TRX942 Digital Recording Transceiver for boom

The TRX942 is an encrypted digital wireless transceiver for boom / parabola use that accepts both traditional analog 48v phantom powered microphone and AES42 digital microphones, like the Schoeps Super CMIT.

The TRX942 is your all-in-one solution for wireless boom and parabolic microphone applications. It performs the functions of a wireless transmitter, an audio monitor channel receiver, a backup recorder and phantom power supply – all with ample battery power in a fully machined aluminum case.

TRX942 Features:

  • Built-in 2.4 GHz receiver, receives IFB audio, timecode and remote control signals from ZaxNet via an IFB100
  • 100% digital modulation wireless transmitter
  • Superb audio quality that rivals a hard-wired microphone
  • Analog dynamic range of 106 dB
  • Digital dynamic range of 124 dB
  • Balanced XLR input with 48 V phantom power
  • 96 hour internal recording with timecode
  • Digital drop-out protection
  • Mic / line level input
  • User selectable 10, 25 or 50 mW output power
  • ZPX rechargeable power system with up to 6 hour run time
  • Graphic LCD display
  • Internal timecode reader / generator
  • RF remote controllable with IFB100 Transmitter
  • Internal headphone monitor mixer
  • 100% machined aluminum case
  • No inter-modulation – up to 50 transmitters, in the same frequency block, can be used together.

Internal Recording
The TRX942′s 96 hour, 24 bit internal loop-recording option is perfect for those times when there’s a lack of available frequencies or when drop-outs cannot be tolerated.  The audio is timecode referenced, recorded on and played back from a removable MiniSD or MicroSD memory card that can be used in any standard SD card reader.

Audio can be recorded, played back and timecode referenced either manually or through remote control commands from the IFB100 transmitter.

The audio is automatically recorded full bandwidth as a .ZAX file. The included ZaxConvert file transfer software (available for both MAC and PC) utilizes sample rate conversion to obtain the sample rate and bit depth of choice when files are imported to your computer. There are two timecode stamped file types to choose from: BWF (Broadcast Wave Format) or MP3 (MPEG-1 Audio Layer 3). MP3 files are great for quickly transferring files over the internet to a transcription house.

Any number of versions of the same recording can be made from a single file.

IFB Audio, Timecode and Remote Control Reception
The TRX942 internal IFB audio receiver allows the TRX942 to receive IFB (confidence) audio directly on the transceiver via the built-in 2.4 GHz receiver. It also receives remote control commands and timecode for remote roll.
