Overview
Specifications

QRX235 and QRX200 Digital Wireless from Zaxcom on Vimeo.

The QRX235 is exactly like the QRX100 but with significantly enhanced distance and range.

There are three components that give the QRX235 its enhanced distance / range.

New digital modulation.
Enhanced receiver design giving it maximum sensitivity while lowering its noise floor.
The elimination in any difference between single and dual mode.

Side mounted LED’s provide visual confirmation of audio and RF reception. A group of 12 multi-colored LEDs are recessed into the side of the QRX200 (Patented). They are visible with the QRX200 mounted in its Zaxcom camera mount and provide the sound mixer with visual confirmation of audio reception at the camera. The LEDs are very bright and can be seen from quite a distance even in bright sunlight.

The QRX235 receives up to 4 channels of 100% digital audio from up to 2 transmitters.

Audio out of the QRX235 can either be an analog signal or as an AES digital signal.

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.

Any combination of Zaxcom TRX series mono or stereo transmitters can be used with the QRX235.

Digital Modulation
