Design

The 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.

Microphone

Supports two lavalier microphones in stereo mode or a single lavalier in mono mode. Connection type: two microdot inputs.

Encrypted Audio

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.

Internal Recording

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.

Better Workflow

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.

Advanced Features

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.

Power

A Motorola BT100 battery provides up to 12 hours of runtime and 48 hours of standby time on a single charge.

MHz Bands

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.)
