TRX Series Digital Recording Wireless™ - Transmitters (patent pending)

Both the TRX900 and TRX900AA are a major advance in the art of professional wireless.  By incorporating an optional IFB receiver into the body of a traditional wireless transmitter, both functions are now combined in a package smaller than most transmitters on the market today.

Also available:

TRX900 | TRX900AA | TRX700 | TRX800 | TRX992

TRX900 Features:

  • Built-in IFB Receiver*
  • Digital modulation wireless transmitter
  • Superb audio quality that rivals a mic cable
  • RF remote control of body-pack (using an IFB100 remote control transmitter)*
  • 96 hour internal recording with timecode*
  • Digital drop-out protection
  • 5 hour running time on single CR123 battery
  • Graphic LCD display
  • Integrated timecode reception
  • Small and lightweight
  • No inter-modulation - up to 50 transmitters, in the same frequency block, can be used together.

TRX900 Options Include:

IFB100 RF Remote Control
The IFB100 transmits IFB audio, timecode and remote control signals to the TRX series digital wireless transceivers on a single RF carrier using a 2.4 Gigahertz signal.  It can be used, license-free, in almost any country.

Internal Recording Capability
The TRX900's 96 hour internal recording option is perfect for those times when drop-outs cannot be tolerated.  Audio can be recorded, played back and timecode referenced either manually or through remote control commands from the IFB100 transmitter.

Timecode Receiver / Generator
The TRX900 has a built-in timecode reader / generator, you can either manually jam or remotely synchronize from the IFB100 transmitter.  The timecode output can be used to feed non-linear recorders like the Zaxcom Deva or Fusion.
