The TRX745 is a wideband plug-on style digital wireless microphone with interchangeable cone 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 TRX745 features, Zaxcom High Density (ZHD), allowing for up to 10 channels of wireless to be operated in one MHz of frequency spectrum space. It also has built-in backup recording with time code, 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:
The TRX745 covers Blocks 20 – 23 (512-608 MHz), the Guard band (614-616 MHz), and the Duplex gap (653-663 MHz). It’s lightweight and durable, housed in a high strength, impact resistant nylon polymer casing and utilizes Zaxcom’s battery saving feature PowerRoll™ to automatically adjust 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 TRX745 works with ZaxNet, Zaxcom’s 2.4-GHz RF network that distributes remote control commands, time code 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.
The TRX745'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.
Starting in 2017, the 617-652 MHz and 663-698 MHz frequencies are being transitioned by the Federal Communications Commission (FCC). Users of wireless microphone devices that operate in any portion of those frequencies must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
