Zaxcom TRX745 Digital Plug-on Transmitter

The Zaxcom TRX745 is a wideband digital transmitter that covers Blocks 20 – 26 (local regulation dependent). The TRX745 works with four different interchangeable cones. These cones support the professional microphone varieties – mono analog, stereo analog, AES, and AES42 – making the TRX745 an ideal choice for wireless boom or handheld microphones.

Zaxcom High Density (ZHD)

The TRX745 features Zaxcom High Density (ZHD), which allows up to 10 channels of wireless to be operated in one MHz spectrum. It also has built-in backup recording with timecode, NeverClip™ for a 126 dB dynamic range, and is fully encrypted.

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.

Channel spacing varies based on the receiver you pair it with:

  • wireless receivers in Mono or XR Modes (as close as 400 KHz channel-to-channel)
  • the QRX235, QRX200, and QRX212, using ZHD mode (as close as 200 KHz channel-to-channel, 300 KHz recommended)
  • the upcoming QRX335, QRX300, and QRX312, using ZHD mode (as close as 100 KHz channel-to-channel)

The USA model of the TRX745 covers the following: Blocks 20 – 23 (512-608 MHz), the Guard band (614-616 MHz), and the Duplex gap (653-663 MHz). The global TRX745 model covers Blocks 20 – 26 (512-698 MHz). The TRX745 is lightweight and durable, with a high strength, impact resistant nylon polymer casing. Additionally, the TRX745 utilizes Zaxcom’s battery saving PowerRoll™ feature to automatically adjust the transmitter output power based on the record status as sent via ZaxNet. As a result, this boosts the output power level up to 100 mW while rolling and powering down to 25 mW while on standby.

ZaxNet™ on Zaxcom TRX745

The TRX745 works with ZaxNet, Zaxcom’s 2.4-GHz RF network that distributes remote control commands, timecode and IFB audio. With ZaxNet, you 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 time code reference giving production sound mixers the ability to replay and remix audio, creating a virtual multi-track playback and re-record system.

The TRX745 sends a Quality Control audio signal over ZaxNet, so you can use an ERX to listen to a lavalier right on the spot, without returning to the cart.

Easily swap the TRX745’s cone. The TRX745 comes standard with the cone of your choice.
