When used with Comtek receivers, the M-72 transmitter reproduces the microphone's quality with indistinguishable difference.

The wide dynamic range of this transmitter is made possible because of its unique soft compressor system which, along with very linear modulation characteristics and low residual FM noise, gives the most natural sound possible from a wireless microphone. To add to its versatility, the M-72 transmitter is available with earlier a companded or non-companded audio system for use with any Comtek receiver. Also, the M-72 will phantom power all types of electret condenser microphones or operate with dynamic microphones.

The M-72, transmitter has an LED indicator to monitor RF output and battery condition, and a Microphone sensitivity adjustment is provided to optimize the signal-to-noise ratio for different applications. The M-72 transmitter utilizes a body induction antenna system. Only the microphone cord extends from the transmitter package enabling the transmitter to have a more uniform radiation pattern when the unit is placed on the body or held in the hand. A slide-open battery compartment makes changing batteries fast and easy. Higher efficiency circuitry provides even longer battery life while maintaining high fidelity and maximum F.C.C. allotted power.
