Let’s break down the name – M (module) RX (receiver) 2 (two transmitters) 1 (for no reason) 4 (up to 4 channels of audio).

RF Performance

Part of Zaxcom’s 4th generation of digital wireless receiver technology the MRX214 sets a new standard for RF performance. The ultra-low noise floor (-135 dB) RF design will provide ultra-long range. The MRX is almost impossible to overload. Close distance transmitters have virtually no effect on the reception of distant transmitters. The RF performance exceeds the previous generation of Zaxcom receivers by 5 dB while enhancing the rejection of interfering signals from things like walkie talkies, cell phones and HD Television transmission by 10 dB.


The MRX214 is the most power efficient digital wireless receiver on the market – the module draws 160 mA @ 13 VDC (80 mA per receiver).
