  • TIMECODE built-in timecode reader and generator
  • ZAXNET provides wireless timecode, ZaxNet audio and remote control between Zaxcom products
  • ZAXNET QC AUDIO quality control confidence monitoring without returning to your cart
  • ZHD MODULATION a 50 KHz wide signal spaced as close as 100 KHz apart with outstanding transmission distance
The TRXLA3 is a wide-band transmitter featuring the new Zaxcom High Density (ZHD) Modulation. ZHD Modulation allows up to 10 channels of wireless to be operated in only 1 MHz of spectrum space. Channel spacing will vary based on the receiver you pair it with.

The wireless signal is only 50 KHz wide and can be spaced as close as 100 KHz channel to channel allowing up to sixty channels of ZHD wireless in a single 6 MHz American television channel. The new modulation is ultra efficient resulting in incredible transmission range.

The ZHD transmitters are capable of running all existing mono Zaxcom modulations maintaining compatibility with all currently produced Zaxcom receivers. ZHD modulation conforms to all currently proposed FCC regulations for spectrally efficient wireless transmission.

A bit about spacing…
•The LA3 paired with any Zaxcom wireless receivers in Mono or XR Modes can be spaced as close as 400 KHz channel to channel
•The LA3 paired with any Zaxcom QRX235, QRX200 or QRX212 in ZHD mode can be spaced as close as 200 KHz channel to channel (300 KHz recommended)
•The LA3 paired with the upcoming QRX335, QRX300 or QRX312 in ZHD mode can be spaced as close as 100 KHz channel to channel

The TRXLA3.5 covers blocks 20 through 23 (512-614MHz) and the TRXLA3.6 covers blocks 23 through 26 (596 – 698 MHz). It’s lightweight and durable, housed in a high strength, impact resistant nylon polymer casing. The LA3 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 100 mW while rolling and powering down to 50 mW while on standby.

The LA3 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 selection, 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 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.

Also available by special order: TRXLA3.5S*** & TRXLA3.6S***
The “S” model is a stereo version of the LA3. The “S” model takes two lavaliere microphones into the single 3-pin LEMO connector. A stereo image is then wirelessly transmitted opening up unlimited possibilities for the enhancement of audio on programming delivered in 5.1 surround format.

***The Stereo version of the LA3 does NOT have NeverClip™ / No ZHD in Stereo Mode***
