ZAXCOM RX-4 interface for MRX 414/212 in H-band (598-698 MHz)

The RX-4 is an interface to convert Zaxcom’s MRX214 and MRX414 receiver modules into stand-alone receivers.

The RX-4 is an inexpensive way to increase the versatility of the MRX, so it can be used as a standalone receiver in addition to being used in a Nova, RX-8 or RX-12, allowing you to expand your system as your needs grow.

The intelligent design of the RX-4 includes two OLED displays for easy visual signal monitoring from up to 4 separate transmitters. Four tricolor LEDs indicate the decoding status of each of the four receive channels.

The audio and power connectors are located directly behind the RX-4 control panel, so cables can be conveniently connected without disassembling the audio bag. The audio output interface is via the two TA5 connectors, either the digital output via the two AES3 connections, or the analog output with a balanced line level. Power is connected via a 4 pin Hirose.

Cabling is the same across the Zaxcom line of receivers, making integration easy.

The RX-4 can receive 4 channels of audio from up to four transmitters when used with the MRX414. Can receive up to 4 channels of audio from two transmitters (stereophonic) when used with the MRX214.

The redesigned two-track front-end filter features a 44 MHz tuning window. There is also an internal passive filter that prevents RX-4 from being overloaded for extended range, no intermodulation, and interference from walkie-talkies and cell phones.

The RX-4 can scan the entire frequency range and instantly scan all bands for 4 receivers to avoid interference in new locations. The receivers can be used anywhere in the RX-4 frequency range, but must be within the 44 MHz window of the tuned front-end filter.

The interface consumes minimal energy and does not emit heat. MRX414 only consumes 350mA when all four channels are active.
