The IFB200 can be used as either a transmitter or receiver. As a transmitter, it sends IFB audio, timecode and remote control commands to Zaxcom's TRX digital recording wireless transmitters and ERX receivers. It can also be used to monitor audio from a QRX or any other ZaxNet transmitter. The signals are carried on a single RF channel over a 2.4 GHz signal and can be used license-free in almost every country with an IFB audio range of approximately 100 feet and an IFB timecode and remote control range of approximately 400 feet.

The front has a graphic LCD screen showing timecode and transmitter status. The IFB200 has a built-in 2-channel mixer for combining two separate channels into a mono transmission signal.
