The TRXLA2 is a brand new version of our most popular talent transmitter, the TRX900LA.

Totally re-designed on the inside the LA2 has a brand new proprietary digital modulation giving it enhanced transmission distance and a wider tuneable frequency range.

The LA2 utilizes Zaxcom’s battery saving feature PowerRoll™. PowerRoll™ automatically adjusts the transmitter output power based on the record status as sent via ZaxNet boosting the output power level up to 125 mW while rolling and powering down to 25 mW while on standby.

Cover four blocks with just one transmitter. The TRXLA2.5 covers blocks 20 through 23 (512-614MHz) and the TRXLA2.6 covers blocks 23 through 26 (596 – 698 MHz).

Designed to be lightweight and durable, the LA2 is housed in a high strength, impact resistant
nylon polymer casing that provides protection from both corrosion and water damage.

The LA2 is fully compatible with all Zaxcom wireless receivers and IFB transmitters.

The LA2 series works with ZaxNet, Zaxcom’s 2.4-GHz RF network that distributes remote
control commands, timecode and IFB audio. With ZaxNet, one can remotely control transmitter
settings such as gain, frequency channel, transport controls and output power levels. When
paired with an IFB100/200 and Deva or Fusion 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 transmitter also sends a Quality Control signal over ZaxNet, a lot of times when you’re micing someone you have to go to the cart to hear how it sounds. Now you can just have an ERX in your pocket and be able to listen to the mic right on the spot.
