Zaxcom ZMT3 ultra-small wideband wireless microphone transceiver with internal recording
Description
Zaxcom ZMT3 ultra-small wideband wireless microphone transceiver with internal recording and NeverClip, 1x NP-50 battery compartment
The ZMT3 is an ultra small bodypack transmitter using Zaxcom’s digital recording & wireless features like NeverClip, PowerRoll and ZaxNet remote control. It is a wide-band transmitter featuring ZHD modulation. The ZMT3 transmitters are also capable of running all existing mono Zaxcom modulations maintaining compatibility with all Zaxcom receivers.
Small and durable, it’s housed in a high strength, impact resistant nylon polymer casing with rounded edges, machined metal and rubber gaskets. This way the 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:
