TRXLA3 (Discontinued)
TRXLA3 (Discontinued)

The TRXLA3 has been distcontinued and replaced by the TRXLA5.

Design

The TRXLA3 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 still remains one of our most popular because of the convenience of AA batteries and the 100 mW power output.

MICROPHONE CONNECTIVITY

The TRXLA3 has a 3-pin micro LEMO connector that supports 3.3-volt lavalier microphones.

Encrypted Audio

The TRXLA3 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.

Internal Recording

Audio is simultaneously transmitted and recorded to a removable microSD card using the highly reliable MARF (Mobile Audio Recording Format) which eliminates file corruption common to recordings due to a dead battery or early card removal.

TRXLA3

NeverClip™

NeverClip™ is available in all modes on the TRXLA3. It works by utilizing two A-D converters to extend the dynamic range of the transmitter to 126 dB, so there’s never any limiter distortion.

ZaxNet™

LA3 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 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

ZaxNet™ QC Audio

The LA3 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. Now you can use an ERX to listen to the mic right on the spot.

PowerRoll™

To extend battery life, PowerRoll™ adjusts the LA3’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.

Modulation Choices for your Environment

The range will always vary depending on your environment, but you’ve got choices to optimize transmission for peak performance. Zaxcom High Density modulation (ZHD) increases the number of available channels from 4 to 9 for every 1 MHz of spectrum space, perfect for reflective environments like busy city streets. XR gives you the maximum distance in less dense / more controlled spaces.

Power

The LA3 runs for up to 7 hours on two AA batteries.

MHz Bands

TRXLA3 is available in the following frequency bands:
“.5 band” (512-608 MHz)
“.6 band” (578-698 MHz) (not available in the U.S.)
