QRX235 4-channel ENG receiver
QRX235 receives up to 4 channels of 100% digital audio from up to 2 transmitters, any combination of mono and stereo transmitters is accepted. The audio output can be either analog or AES. It also features our patented side mounted LED’s, these provide visual confirmation of audio and RF reception. The LED’s are very bright and are visible with the QRX235 mounted in its Zaxcom camera mount even in bright sunlight.
Main Benefits
- 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
