CONNECTIVITY
QRX235 can output AES digital audio or analog audio at -35dB mic level, -10dB consumer level, or 0dB line level on 2 x TA5 connectors. IFB audio is input via an 1/8″ (3.5mm) stereo mini jack. Timecode I/O is also on an 1/8″ (3.5mm) stereo mini jack. The two serial loop USB connectors are for connecting to ZaxMote or other QRX200’s to share the QIFB remote control feature.
CHANNEL COUNT
The QRX235 receives up to four channels of audio from two separate transmitters. You can use it with any combination of mono and stereo UHF transmitters we make, but it’s most often paired with our TRXCL3 for a full confidence monitor return with or without timecode.
RF PERFORMANCE
The QRX235 with QIFB is block specific, this means it receives on its designated frequency window and all other interfering high-level signals outside this frequency space will be blocked out. The nerds call this desensing. We let the good stuff in (your radio mic transmitters) and we keep the bad stuff out (walkie talkies, the follow focus, etc.). Think of it like the bouncer outside a nightclub.
