The RX-4 is an interface to convert Zaxcom’s MRX214 and MRX414 receiver modules (sold separately) into stand-alone receivers.
The RX-4 is an affordable way to increase the versatility of an MRX so it can be used as a stand-alone receiver in addition to its use in a Nova, RX-8, or RX-12, allowing for your system to expand as your needs grow. The combo is a great way to get started with the Zaxcom Digital Recording Wireless ecosystem.
The RX-4’s intelligent design includes two OLED displays to easily visually monitor data from up to 4 separate transmitters. There are four tricolor LEDS that indicate the decode status of each of the four receive channels and push buttons for simple navigation of menus.
The audio and power connectors are located directly behind the control panel of RX-4 so cables can be conveniently attached without taking apart the sound bag. The audio output interface is via two TA5 connectors, either digital out via two AES3 connections or balanced line level analog out. Power is connected via a 4-pin Hirose.
Cable wiring is the same across the entire line of Zaxcom receivers for easy integration.
The RX-4 can receive 4 channels of audio from up to four transmitters when used with an MRX414. It can receive up to 4 channels of audio from two transmitters when used with an MRX214.
The redesigned dual track tuned front end filter features a 44 MHz tuning window. There’s also an internal passive filter making it impossible to overload the RX-4 for increased range, no intermodulation, and no interference from walkie talkies and mobile phones.
The RX-4 can scan the entire frequency range and re-freq all 4 receivers instantly to avoid localized interference at new locations. Receivers can be used anywhere in the frequency range of the RX-4, but need to be within the 44 MHz window of the tuned front-end filter.
The interface consumes no power; it runs off the module and produces no additional heat. The MRX414 consumes only 350ma when all four channels are active.
