Design Matters

The QRX200 is a 200 MHz wide-band ENG receiver. It has a tunable tracking front end filter for receiving any frequency in any block from 20 through 26, or 512 – 698 MHz, all while still filtering out unwanted RF.

QRX200Rear Connector View


QRX200 can output AES digital audio or analog audio at -35dB mic level, -10dB consumer level, or 0dB line level on 2 x TA5 connectors. The two serial loop USB connectors are for connecting to another QRX200 or a QRX235 to share the QIFB remote control feature.

Channel Count

The QRX200 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.

RF Performance

The QRX200 has an automatic tracking front end filter, so you can receive on any frequency in any block from 20 through 26 (512-698MHz) with impressive range. Here’s how that works – the filter allows signals within the 35 MHz tunable window into the receiver while blocking the interfering high-level signals outside this window. 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.

Frequency Range

The QRX200 is wide-band and covers all frequency blocks from 20 through 26 (512-698 MHz).


The QRX200 is powered externally via any power source 9 to 18 volts on a single Switchcraft 760k connector.
