The ZaxNet QIFB option is available in the QRX235 – The QIFB allows you to send or receive ZaxNet audio and timecode, as well as TRX commands from your QRX235.

The QIFB option board gives the QRX235 the ability to send and receive IFB audio, broadcast timecode for synchronization and/or remote roll, and sends transmitter remote control commands (RF frequency, audio level, etc.). It also adds a mono headphone output jack to the receiver.

As an IFB transmitter, the QIFB option board can send one audio channel with SMPTE timecode reference. The 2.4 GHz IFB transmission is compatible with all Zaxcom IFB receivers and TRX series digital wireless transceivers outfitted with IFB receive functionality. In receive mode, the QIFB option board receives IFB audio and timecode for camera synchronization.

QRX235 also receives remote control commands from a TRX series transmitter over the UHF frequency band for selecting the confidence monitor return source.

A typical setup would have the QRX235 mounted to a camera and either one or two TRX900AA’s with Stereo Adapters in the sound bag. The TRX900AA receives the audio / timecode signal. The monitor audio is your confidence loop and the timecode controls the start/stop of the internal backup recorder built into the transmitter.
