Talk about Inconspicuous!

Small & Curvy

Bells & whistles

Some don't like it hot!

ZMT3 is about the size of a Zippo lighter with ergonimically rounded edges and a removable antenna weighing in at only 2.2 oz with battery Wide-band transmitter with built-in recording that's RF remote controllable - what more could you ask for? ZMT3 runs cool, the combination of the nylon composite case and its power efficiency make the heat transfer practically non existent

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 nonexistent.

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)
