Zaxcom QRX235

Description

Zaxcom QRX235 4-channel ENG receiver with QIFB internal 2.4 GHz IFB audio, timecode and remote control transceiver

The QRX235 is a 35 MHz wide ENG receiver. It can ordered in a specific frequency block between 512 to 698 MHz. Three key components give QRX235 its enhanced distance / range:

new digital modulation

enhanced receiver design gives maximum sensitivity while lowering its noise floor

the elimination in any difference between single and dual mode

The 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 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.

The ZaxNet QIFB is standard in the QRX235. The QIFB allows you to send or receive ZaxNet audio and timecode, as well as TRX commands from your QRX235.

If you’ve got QIFB be sure to check out ZaxMote.
