ZAXCOM QRX235
The QRX235 is a 35 MHz wide ENG receiver. It can ordered in a specific frequency block between 512 to 698 MHz. Three components give the QRX235 its enhanced distance/range:
- digital modulation
- enhanced receiver design giving it 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.
FEATURES:
- full confidence: the QRX235 with QIFB gives you a total confidence loop, it receives audio and timecode then sends it right back.
- seeing is believing: ultra bright multi-colored side mounted LED's gives you visual conformation that RF and audio are making it to the camera.
