Zaxcom TRXCL5 Wide-Band Camera Link Transmitter
A wide-band camera link transmitter, the Zaxcom TRXCL5 sends audio with embedded timecode over UHF from the sound bag to the camera.
At the same time it feeds audio and timecode to ERX receivers over ZaxNet’s 2.4 GHz signal and sends remote control commands to Zaxcom transmitters. It serves film, television, and ENG work. At the camera it pairs with Zaxcom receivers such as the QRX200, RX200, and QRX235, or an MRX414 in an RX-4.
Inputs and Timecode
A TA5 input takes balanced stereo line-level audio or AES digital audio with sample rate conversion. Timecode arrives through the BNC jack or over ZaxNet. Mute Till Jam holds the timecode output until the internal generator is jammed, and Auto Jam starts and stops recording from the incoming timecode.
Encryption, Recording, and Intermodulation
The fully encrypted digital transmission prevents eavesdropping, and the TRXCL5 records the same audio to an internal microSD card. Recordings use Zaxcom’s MARF format, which keeps the file intact if the battery dies or the card comes out early. The TRXCL5 also keeps intermodulation in check when several transmitters work close together.
ZaxNet and the GUI Bridge
ZaxNet is Zaxcom’s 2.4 GHz control link. From a ZRC remote or any ZaxNet device, the operator can change the frequency, output power, and input gain, start and stop the recorder, manage timecode, and format the card.
An RS422 port links to the Zaxcom GUI Bridge, which sets up and controls Zaxcom wireless, including URX50 and URX100 receivers, from any device with internet access.
Power and Frequencies
A 4-pin Hirose connector takes 8 to 18 V DC, and the output is selectable at 25, 50, or 100 mW. In the US the TRXCL5 tunes 512.0 to 607.9, 614.1 to 615.9, and 653.1 to 662.9 MHz; elsewhere it covers 512 to 698 MHz. The lightweight metal housing weighs 7.3 oz.
