Zaxcom TRX743

The Zaxcom TRX743 is an all digital transmission plug-on style transmitter that supports all professional varieties of microphones: analog mono, analog stereo and AES43. The plug-on will come either a mono, stereo or AES43 cone based on your choice.

It features Zaxcom’s patented internal backup recording, ZaxNet remote control, and NeverClip. NeverClip is a dual A-D preamp system providing an extended dynamic range of 127 dB.

With an internal timecode-referenced audio recorder that backs up all wireless transmissions on a removable microSD card, the TRX743 eliminates the possibility of audio loss due to interference or signal dropout. The TRX743 is powered by three AA lithium or rechargeable NiMH batteries. It also carries a variable RF power output of 25, 50 or 125 mW.

With ZaxNet, Zaxcom’s 2.4 GHz RF network that enables distribution of remote control signals, timecode and metadata, TRX743 users will be able to control gain and audio replays remotely via a timecode reference so that multiple Zaxcom wireless systems can replay audio in sync. The ZaxNet integration also will allow production sound mixers to remix audio from multiple transmitters, creating a virtual multi-track playback and re-record system.
