Product Description

QRX235 and QRX200 Digital Wireless from Zaxcom on Vimeo.

The QRX235 Rx features all new digital modulation and a QIFB option. The digital modulation gives the QRX235 significantly enhanced distance and range and the QIFB upgrade adds the ability to read time code wirelessly, all while it receives up to 4 channels of 100% digital audio from up to 2 transmitters. Any combination of Zaxcom TRX series mono or stereo transmitters can be used with the QRX235.

The QRX200 outputs audio in both analog and AES digital formats and receives 4 channels of 100% digital audio from up to 2 transmitters . It's small and lightweight to provide optimum compatibility and functionality for broadcasters and freelancers alike.

A group of 12 multicolored LED's are recessed into the side of the QRX200 for visual confirmation of audio reception. The LED's are very bright and can be seen from quite a distance even in bright sunlight.
