The QRX200 is a 200 MHz wide ENG receiver. A tunable tracking front end filter is featured in the QRX200 so you can receive any frequency in any block from 20 through 27 or 512 – 698 MHz while still filtering out unwanted RF.

There are three components that give the QRX200 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.

Receives up to 4 channels of 100% digital audio from 2 transmitters

The QRX200 outputs audio as an analog signal or as an AES digital signal.

Any combination of Zaxcom mono or stereo transmitters can be used with the QRX200.
