Zaxcom VTX1 VHF and 2.4 GHz IFB Transmitter
The Zaxcom VTX1 sends IFB audio on VHF and on 2.4 GHz ZaxNet from one box, with encrypted audio, timecode, and internal recording built in.
On VHF it tunes 192 to 217 MHz in 25 kHz steps, in FM analog mode or a fully encrypted digital mode. Either way it feeds the Zaxcom VRX1 receiver, and FM analog mode also works with Comtek receivers and other gear in the same range.
ZaxNet
The 2.4 GHz side carries IFB audio, timecode, metadata, and remote control to Zaxcom transmitters and receivers. Over ZaxNet, the VTX1 changes a transmitter’s frequency, preamp gain, and output power, and puts the transmitter’s recorder in record, playback, or stop, without anyone approaching the talent.
ZaxNet runs on a single 2.4 GHz channel that can be used license-free in almost every country.
Encryption and Recording
Digital VHF audio and 2.4 GHz audio are fully encrypted; FM analog mode is not. A microSD slot records the transmitted audio with timecode as a backup or reference for post, in MARF files that survive power loss or early card removal.
Inputs and Power
A TA5 input takes balanced stereo line-level audio or AES with sample rate conversion, a BNC jack takes timecode, and USB handles software updates. Output reaches 50 mW on VHF and on 2.4 GHz. The VTX1 runs from 8 to 18 V DC through a Hirose connector, drawing 180 mA.
