Wide band camera link transmitter


The TRXCL3 offers superb sound quality, a compact design and incredible ease of use of for those in film, television or ENG applications. Weighing less than a half pound (7.3 oz) it features internal recording, encrypted audio, timecode, ZaxNet™ functionality and more.

As a wide-band transmitter, it’s capable of sending audio with embedded timecode to camera through its UHF signal to QRX200, RX200 and QRX235 Zaxcom receivers and via ZaxNet™, a 2.4 GHz signal, to an ERX3TCD receiver.

Audio is 100% digital and fully encrypted to keep transmissions private. The transmitter is also immune to intermodulation which occurs when multiple transmitters in close proximity to each other mix together.

The TRXCL3 can simultaneously transmit and record internally to a microSD card. Files are saved using the highly reliable lossless MARF (Mobile Audio Recording Format) and can then be instantly converted to Broadcast Wave Format (BWF) or MP3 via ZaxConvert, free software available for MAC or PC.

The unit features a single TA5 audio input that can be used as balanced stereo line level or sample rate converting AES. A 3.5mm output allows for audio out and a BNC connector provides a connection for timecode in or out. An OLED lets users easily navigate the intuitive menu.

Additionally, the TRXCL3 is equipped with ZaxNet™ to send or receive timecode, scratch track audio and remote control commands. Zaxcom High Density (ZHD) modulation has been added to increase the number of channels in the wireless spectrum.


  • 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 our out.


  • The TRXCL3 transmits using 100% digital modulation and audio is fully encrypted to keep recordings private.


  • 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 TRXCL3 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 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.
