ZMT3-X is our longest running and most durable transmitter for sound recordists. It's made from tough nylon polymer and rubber materials to maximize performance out in the field.
Supports two lavalier microphones in stereo mode or a single lavalier in mono mode. Connection type: two microdot inputs.
Audio is transmitted using 100% digital modulation. Transmitting digitally allows the audio to be encrypted. Zaxcom uses an advanced encryption system to keep audio private.
Transmitted audio can be simultaneously recorded internally to a microSD card. Audio files are recorded using the highly reliable lossless MARF (Mobile Audio Recording Format) which eliminates file corruption common to recordings due to dead battery or early card removal.
The ZMT3-X provides 128 dB dynamic range in mono mode and 108 dB in stereo mode. Selectable power of 25, 50 or 75 mW. An OLED displays key information.
ZaxNet is a long range remote control system allowing users to change frequency, input gain and power output without removing the transmitter from the talent.
Zaxcom High Density modulation (ZHD) increases the number of available channels to 9 in one MHz of spectrum space.
A Motorola BT100 battery provides up to 12 hours of runtime and 48 hours of standby time on a single charge.
ZMT3-X is available in the following frequency bands:
".5 band" (512-608 MHz)
".6 band" (596-698 MHz) (not available in the U.S.)
Talk about Inconspicuous
Small & Curvy
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
Bells & whistles
Wide-band transmitter with built-in recording that's RF remote controllable - what more could you ask for
Some don't like it hot!
ZMT3 runs cool, the combination of the nylon composite case and its power efficiency make the heat transfer practically non existent
