ZAXCOM – TRX743 Plug-on Wireless Transmitter with NeverClip (3AA battery)

The TRX743 is a wide-band plug-on style digital wireless microphone transmitter with interchangeable cones to support all professional microphone varieties, mono analog, stereo analog, AES and AES42, making it an ideal choice for wireless transmission directly from boom poles or handheld microphones.

The TRX743 features 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 TRX743 paired with any Zaxcom wireless receiver in mono or XR modes can be spaced as close as 400KHz channel to channel
• The TRX743 paired with any Zaxcom QRX235, QRX200 or QRX212 in ZHD mode can be spaced as close as 200KHz channel to channel (300KHz recommended)
• The TRX743 paired with the QRX335, QRX300 or QRX312 in ZHD mode can be spaced as close as 100 KHz channel to channel
• The TRX743.5 covers channels 26 through 38 (512 to 614MHz) and the TRX743.6 covers channels 36 through 49 (596 to 698MHz).

Its body is constructed from a combination of high strength nylon polymer and aluminum. The 743 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 743 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 TRX743 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.

The TRX743’s cones are easily swapped in the field for ultimate flexibility. It comes standard with the cone of your choice, extra cones can be purchased as accessories.
