Information

Zaxcom ZMT4 Miniature Digital Transmitter w/ Internal Recording (Select Option)

The ZMT4 has taken digital recording wireless to the next level with longer battery life, NeverClip™ in all modes, and power for all microphones – from a 5V lavalier to a 48V phantom powered mic – and a new ultra-low noise preamp.

Deliver pristine audio quality with our ZMT4, an incredibly small, lightweight, talent-friendly transmitter ideal for sound professionals. Weighing only 2.2oz (62g), the ZMT4 is constructed from a high-strength, impact-resistant nylon polymer casing with rounded edges and machined metal that’s cool to the touch.

Microphone Connectivity

The ZMT4 has a wide range of power to cover nearly any professional analog microphone – 5V lavalier mics as well as condenser, balanced dynamic, or ribbon microphones running at 12, 24, 36, or 48V.

Perfect for boom pole operation, the ZMT4 can be positioned at the top of a boom pole directly behind the microphone instead of near the bottom. By removing the internal or external cable, operators can eliminate cable noise that can affect the audio track. Boom microphone connectivity is via a 3-pin balanced LEMO.

Encrypted Audio

The ZMT4 transmits using 100% digital modulation allowing audio to be fully encrypted. Digital encryption is the only way to keep all audio transmission private. A digital transmission also provides audio quality superior to all analog systems.

Microphone Preamp

The ZMT4 features an all-new preamp design. The preamp and A-D combination now utilizes NeverClip™ with both lav and balanced boom mics, making the environment and self-noise of the microphone the dominant noise components.

NeverClip™

NeverClip™ is available in all modes on the ZMT4. It works by utilizing two A-D converters to extend the dynamic range of the transmitter to 136 dB, so there’s never any limiter distortion.

Internal Recording

Audio is simultaneously transmitted and recorded to a removable microSD card using the highly reliable MARF (Mobile Audio Recording Format) which eliminates file corruption common to recordings due to a dead battery or early card removal.

ZaxNet™

ZMT4 is equipped with ZaxNet™, a long-range remote-control system allowing the user to change the frequency, pre-amp gain, sleep mode, and place the internal recorder in record, playback, and stop modes – all without ever needing to disturb talent.

PowerRoll™

To extend battery life, PowerRoll™ adjusts the ZMT4’s power level to 50mW when the audio received from it is being recorded by a ZaxNet™ compatible recorder. When the transmitter audio isn’t being recorded the power is automatically reduced to 10mW.

Modulation Choices for your Environment

The range will always vary depending on your environment, but you’ve got choices to optimize transmission for peak performance. Zaxcom High Density modulation (ZHD) increases the number of available channels from 4 to 9 for every 1 MHz of spectrum space, perfect for reflective environments like busy city streets. XR gives you the maximum distance in less dense / more controlled spaces.

Power

The ZMT4 has better battery life than its predecessor. A single NP-50 battery provides up to 7 hours of runtime with a lavalier running at 5v and up to 5 hours of runtime while using a 12-48v boom microphone.

ZMT4 is available in the following frequency bands:

  • “.5 band” (512-608 MHz)
  • “.6 band” (578-698 MHz) (not available in the U.S.)
