Zaxcom TRXLA5 Bodypack Transmitter

Running on two AA batteries, the Zaxcom TRXLA5 is a UHF bodypack transmitter with encrypted digital audio, internal recording, and timecode.

Audio goes out as a fully encrypted digital signal while a copy records to a microSD card in the transmitter. Recorded files carry timecode, so the audio can be replayed against a timecode reference and remixed as virtual multitrack playback.

Microphones and Power

A 3-pin micro LEMO input powers 5 V lavalier mics from any brand. Two lithium AA batteries give more than 10 hours at 100 mW, and alkaline and NiMH cells work too.

ZaxNet Remote Control

From a ZRC remote or any ZaxNet device, the operator can change the frequency, output power, and input gain, start and stop recording, manage timecode, and format the card without disturbing the talent. Quality-control audio also goes out over ZaxNet, so the mic can be checked on the spot with an ERX receiver.

NeverClip and ZHD

NeverClip extends the dynamic range to 126 dB for clean audio when levels jump. ZHD modulation fits more channels into each megahertz of spectrum, with Mono, Stereo, XR, ZHD48, and ZHD96 modes for crowded RF environments.

Frequency Bands

In the United States the TRXLA5 tunes 512.0 to 607.9 MHz, 614.1 to 615.9 MHz, and 653.1 to 662.9 MHz. Outside the US it covers 512 to 698 MHz. Output power is 10, 20, or 100 mW, as local regulations allow.
