Zaxcom ZMT3-HM

Description

Zaxcom ZMT3-HM ultra-small wideband plug-on transceiver with internal recording, 1x NP-50 battery compartment

The ZMT3-HM is an ultra-small wide-band digital plug-on transmitter filled with features like internal recording and PowerRoll. A perfect solution for ENG applications, the ZMT3-HM combines wide-band transmission, selectable 12, 24, 32 and 48V Phantom power and a rechargeable internal battery for easy use and fluid functionality. The plug-on transmitter also has selectable output power of 25, 50, or 75 mW with the battery providing up to 5 hours of continuous operating time.

Weighing only 88 grams, it’s housed in a high strength, impact resistant nylon polymer casing with rounded edges, machined metal and rubber gaskets to protect it against the harshest of production environments. The combination of the nylon composite case and its power efficiency makes heat transfer practically nonexistent, allowing the ZMT3-HM to run cool.

Like all Zaxcom digital wireless, the ZMT3-HM transmits encrypted audio using full digital modulation, resulting in audio quality far superior to any analog system. Audio can also be recorded internally to a microSD card as a safety backup or when there is radio frequency (RF) interference or distance issues. Files are saved on the card using the highly reliable lossless MARF (Mobile Audio Recording Format) that eliminates file corruption common to recordings due to dead battery or early card removal.

The ZMT3-HM can provide a timecoded reference recording matching the camera’s timecode and features Zaxcom’s High Density modulation (ZHD) that allows up to channels ten of wireless to be operated in one MHz of spectrum space. The integrated antenna is completely invisible. A 3-pin XLR connector makes it ideal for any microphone.

Additionally, the ZMT3-HM has ZaxNet to provide remote control functions through a selectable 2.4GHz signal. Users can adjust frequency and pre-amp gain while having the ability to place its built-in recorder into record, playback and stop modes. Combining a Zaxcom Nomad or IFB transmitter, the ZMT3-HM pre-gain settings can be instantly adjusted eliminating audio distorted by the transmitter limiter.

The ZMT3-HM can be ordered in one of two configurations:

ZMT3.5-HM: covering channels 26 through 38 (512 to 614 MHz)

ZMT3.6-HM: covering channels 36 through 49 (596 to 698 MHz)
