The ZMT3- Flex is a tough wireless designed for tough demands. Deliver pristine audio quality with a bendable wireless transmitter designed to capture the on field experience of professional sports. Weighing only 3oz, the ZMT3-Flex is encased in a soft yet durable silicon rubber that allows the transmitter to bend and flex, providing an elevated level of safety for the professional sports player.

The ZMT3-Flex works with either a single mono or dual lavalier microphones in stereo via two microdot input connectors.

The ZMT3-Flex transmits using 100% digital modulation resulting in audio that's fully encrypted. Digital encryption is the only way to keep all audio transmission private. A digital transmission also provides audio quality far superior to an analog system.Audio can be recorded internally to a microSD card 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-Flex provides a 128 dB dynamic range in mono and 108 dB in stereo with no limiting or compression distortion. External audio and battery status levels are seen on the OLED or at the receiver. Equipped with ZaxNet™, you can remotely change the frequency, pre-amp gain, output power or place the internal recorder in record, playback and stop modes.

The ZMT3-Flex can be ordered in one of two configurations:
ZMT3.5 - covering blocks 20 through 23 (512-614 MHz)
ZMT3.6 - covering blocks 23 through 26 (596 – 698 MHz)
