Zaxcom QRX235 (Block 20: 518.0 to 542.0)

Three key components give 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

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.

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.

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