Design Matters

Deliver pristine audio quality with the TRXCL4 wide-band camera link transmitter for sound professionals in film, television, or ENG applications.

Weighing 7.3 oz, it’s constructed from an impact-resistant metal casing that’s cool to the touch. A bright OLED display provides easy menu navigation.


The TRXCL4 sends audio with embedded timecode to camera via a UHF signal to any Zaxcom receiver – QRX200, RX200, QRX235 or MRX/RX-4. It can also send audio and timecode via ZaxNet’s 2.4 GHz signal to an ERX3TCD receiver, or remote control commands to any Zaxcom digital recording wireless transmitter.

A TA5 audio input offers balanced stereo line level or sample rate converting AES. The BNC connector provides timecode in.

New on the CL4 is an RS422 port for direct connection to the Zaxom GUI Bridge so you can easily setup URX50/100 and remote control your wireless via any device that can access the internet.

TRXCL4 Rear Panel


The TRXCL4 transmits using 100% digital modulation and audio is fully encrypted to keep recordings private.

Internal Recording

Audio can be simultaneously transmitted and internally recorded to a microSD card using MARF (Mobile Audio Recording Format) which eliminates file corruption common to recordings due to loss of power or early card removal.


The TRXCL4 is designed to limit intermodulation which can occur when multiple transmitters are in close proximity to each other and mix together.


ZaxNet allows you to send scratch track audio, timecode, and remote control commands.
