Zaxcom TRXLA3

Description

Zaxcom TRXLA3 wideband wireless microphone transceiver with internal recording and NeverClip, 2x AA battery compartment

The TRXLA3 is a wide-band transmitter featuring the Zaxcom High Density (ZHD) Modulation. ZHD modulation allows up to 10 channels of wireless to be operated in only 1MHz of spectrum space. Channel spacing will vary based on the receiver you pair it with. The wireless signal is only 50KHz wide and can be spaced as close as 100KHz channel to channel allowing up to sixty channels of ZHD wireless in a single 6MHz 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.

The TRXLA3 paired with any Zaxcom wireless receivers in mono or XR Modes can be spaced as close as 400KHz channel to channel

The TRXLA3 paired with any Zaxcom QRX235, QRX200 or QRX212 in ZHD mode can be spaced as close as 200KHz channel to channel (300KHz recommended)

The TRXLA3 paired with the QRX335, QRX300 or QRX312 in ZHD mode can be spaced as close as 100KHz channel to channel

The TRXLA3.5 covers channels 26 through 38 (512 to 614MHz) and the TRXLA3.6 covers channels 36 through 49 (596 to 698MHz)

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 while rolling and powering down while on standby.

The TRXLA3 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. The TRXLA3 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 are: TRXLAS3.5 & TRXLAS3.6

The TRXLAS model is a stereo version of the TRXLA3. 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.

Note: the stereo versions of the TRXLA3 do NOT have NeverClip and no ZHD in stereo mode.
