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

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 are the TRX700 plug-on style transmitter and the TRX800 handheld wireless transmitter.

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 12 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.

Time Code 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.
