The TRXLA5 is a wide-band bodypack transmitter that runs on two AA batteries. It's lightweight and durable, housed in a high-strength, impact-resistant nylon polymer casing. This transmitter design has remained popular because of the convenience of AA batteries and the 100 mW power output. The TRXLA5 is has a 512 to 698 MHz frequency range and supports 5 Volt microphones.

The TRXLA5 transmits using 100% digital modulation allowing audio to be fully encrypted. Digital encryption is the only way to keep all audio transmission private. A digital transmission also provides audio quality superior to analog systems.

Audio is simultaneously transmitted and recorded to a removable microSD card using the highly reliable MARF (Mobile Audio Recording Format). MARF ensures file corruption never happens if a battery dies or someone accidentaly removes a card too early.

The TRXLA5 is equipped with ZaxNet, a long-range remote-control system allowing the user to change the frequency, pre-amp gain, sleep mode, and place the internal recorder in the record, playback, and stop modes - all without ever needing to disturb talent. The units can also replay audio via a timecode reference, giving production sound mixers the ability to replay and remix audio, creating a virtual multi-track playback and re-record system. The TRXLA5 also sends a Quality Control audio signal over ZaxNet so when micing someone you don't have to go to the cart to hear how it sounds. You can use an ERX to listen to the mic right on the spot.

To extend battery life, PowerRoll adjusts the TRXLA5's power level to 100mW when the audio received from it is being recorded by a ZaxNet compatible recorder. When the transmitter audio isn't being recorded the power is automatically reduced to 25mW.
