Zaxcom  TRX942

The TRX942 is an encrypted digital wireless transceiver for boom / parabolic use that accepts both traditional analog 48v phantom powered microphone and AES42 digital microphones, like the Schoeps Super CMIT.

The TRX942 is your all-in-one solution for wireless boom and parabolic microphone applications. It performs the functions of a wireless transmitter, an audio monitor channel receiver, a backup recorder and phantom power supply – all with ample battery power in a fully machined aluminum case.
