The ZMT4-X is an addition to the ZMT4 family, it runs up to 16 hours on a single charge! It's our longest-running and most durable transmitter, it's made from tough nylon polymer and rubber materials to maximize performance out in the field. 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.

Supports two lavalier microphones in stereo mode or a single lavalier in mono mode. Connection type: two microdot inputs. 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 a dead battery or early card removal.

The ZMT4-X provides a 136 dB dynamic range in both mono or stereo modes. Power is selectable, either 25 or 50 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/BT110 (PMNN4468A) battery provides up to 16 hours of runtime and 48 hours of standby time on a single charge.

The ZMT4-X can be ordered in one of two configurations:

• ZMT4.5-X: covering channels 26 through 38 (512 to 614 MHz)
• ZMT4.6-X: covering channels 36 through 49 (596 to 698 MHz)
