The ZMT3 is an ultra small bodypack transmitter filled with Zaxcom's Emmy Award winning Digital Recording Wireless features like NeverClip™, PowerRoll™ and ZaxNet remote control. This tiny unit will surely open the door to new ways of recording sound for television, sports, theatre and feature films.

The ZMT3 is a wide-band transmitter featuring Zaxcom's High Density (ZHD) Modulation. The ZMT3 transmitters are also capable of running all existing mono Zaxcom modulations maintaining compatibility with all Zaxcom receivers. ZHD modulation conforms to all currently proposed FCC regulations for spectrally efficient wireless transmission.

Small and durable, it's housed in a high strength, impact resistant nylon polymer casing with rounded edges, machined metal and rubber gaskets. ZMT runs cool, the combination of the nylon composite case and its power efficiency make the heat transfer practically non existent.

The ZMT3 works 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. The ZMT3 also sends a Quality Control audio signal over ZaxNet, so when miking someone you don’t have to go to the cart to hear how it sounds, you can use an ERX to listen to the mic right on the spot.

The ZMT3 can be ordered in one of two configurations:
ZMT3.5 - covering blocks 20 through 23 (512-614 MHz)
ZMT3.6 - covering blocks 23 through 26 (596 – 698 MHz)
