 Design Matters

Deliver pristine audio quality with the TRXCL3 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 TRXCL3 sends audio with embedded timecode to camera via a UHF signal to QRX200, RX200 and QRX235 receivers or through ZaxNet’s 2.4 GHz signal  to an ERX3TCD receiver.

A TA5 audio input offers balanced stereo line level or sample rate converting AES. The 3.5mm output delivers audio and the BNC connector provides timecode in or out.

Encrypted Audio

The TRXCL3 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.

Better Workflow

The TRXCL3 is designed to limit intermodulation which can occur when multiple transmitters are in close proximity to each other and mix together.

Advanced Features

ZaxNet allows you to send or receive timecode, scratch track audio and remote control commands. Zaxcom High Density (ZHD) modulation increases the number of available channels in the wireless spectrum.

MHz Bands

  • “.5 band” (512-614 MHz)
  • “.6 band” (596-698 MHz)
