TRX Series Digital Recording Wireless™ - Transmitters (patent pending)
The TRX900 and TRX900AA are a major advancement 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.
The TRX990 wireless microphone transceiver is designed for Boom Pole and Sports Parabola applications. It takes the place of a traditional wireless transmitter, a 48V phantom power supply, an IFB receiver and a walkie talkie all while providing superb audio quality and extended operating time.
Also availabe are the TRX700 Plug-on style transmitter and the TRX800 handheld wireless transmitter.

TRX900 Features:
- Built-in IFB Receiver*
- Digital modulation wireless transmitter
- Superb audio quality that rivals a hard wire
- RF remote control of body pack
- 12 hour internal recording with Time Code*
- Digital drop-out protection
- 2 ms transmission delay
- 5 hour running time on single 123 battery
- Graphic LCD display
- Integrated Time Code transmission
- Small and lightweight
- No inter-modulation - up to 50 transmitters in the same frequency block can be used
together at the same time.
*optional
Options Include:
IFB100 RF Remote Control
The IFB100 transmits IFB audio, time code 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 in almost any country license-free.
Internal Recording Capability
The TRX900's 12 hour internal recording option is perfect for when drop-outs cannot be tolerated. Audio can be recorded, played back and time code referenced either manually or through remote control commands from the IFB100 transmitter.
Time Code Receiver / Generator
The TRX900 has a built-in Time Code reader / generator, you can either manually jam or remotely synchronize from the IFB100 transmitter. The time code output can be used to feed non-linear recorders like the Zaxcom Deva or Fusion.
