The QRX300 is a special order receiver designed to receive a single channel of 100% digital audio through ZHD48 modulation. The receiver has very narrow filters that allow for a 50 KHz wide signal to be received with a channel spacing as close as 100 KHz.
The QRX300 is 200 MHz wide. A tunable tracking front end filter ensures reception of any frequency in block 20 through 27 (512 – 698 MHz) while still filtering out unwanted RF. The QRX300 outputs audio as an analog signal or as an AES digital signal.
The QRX300 is designed specifically for applications where limited spectrum bandwidth is available and a large number of wireless microphones need to be used together and a latency of 18 milliseconds is not a concern. This unit can only receive ZHD48 modulation. It is not compatible with XR, US Mono or ZHD96.
