Zaxcom TRX743 Plug-on Boom Transmitter

The Zaxcom TRX743 Plug-on Boom Transmitter is a wide-band plug-on style digital wireless microphone 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 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 TRX743 paired with any Zaxcom wireless receivers in Mono or XR Modes can be spaced as close as 400 KHz channel to channel
  • The TRX743 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 TRX743 paired with the upcoming QRX335, QRX300 or QRX312 in ZHD mode can be spaced as close as 100 KHz channel to channel

The TRX743.5 covers blocks 20 through 23 (512-614MHz) and the TRX743.6 covers blocks 23 through 26 (596 – 698 MHz). 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 to 100 mW while rolling and powering down to 25 mW while on standby.

The Zaxcom TRX743 Plug-on Boom Transmitterworks 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 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.
