NAB 2017: Zaxcom Intros ZMT3-HM Plug-On Transmitter

Zaxcom today has expanded its Digital Recording Wireless line with ZMT3-HM, a new plug-on transmitter that pairs high-end features with sleek ergonomics. Well-suited to 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 ZMT3-HM is available in two frequency ranges: 512-614 MHz (blocks 20-23) and 596 – 698 MHz (blocks 23-26). The plug-on transmitter also has selectable output power of 25, 50, or 75 mW with the battery providing up to five hours of continuous operating time.

Weighing 3.1 oz. (88 g), 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.

“We’re particularly happy to expand our line of plug-on transmitters this year,” says Colleen Goodsir, director, sales and marketing, Zaxcom. “The ZMT3-HM is a perfect fit for those in the ENG market looking for reliable wireless in a compact solution.”

Like all Zaxcom digital wireless, the ZMT3-HM transmits encrypted audio using 100%-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. They can then be instantly copied to Broadcast Wave Format (BWF) or MP3 via ZaxConvert, free software available for MAC or PC.

The ZMT3-HM can provide a timecoded reference recording matching the camera’s timecode and features Zaxcom’s High Density modulation (ZHD), allowing up to 10 channels of wireless to be operated in 1 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 2.4-GHz signal. Users can adjust frequency and preamp gain while having the ability to place its built-in recorder in record, playback, and stop modes. Combining a Zaxcom Deva 24, Nomad or IFB transmitter, the ZMT3-HM pregain settings can be instantly adjusted eliminating audio distorted by the transmitter limiter.
