Transceiver Microphone Preamp/Filter

Download Manual

The following text is from the manufacturer:

Two-way radios have historically used dynamic type microphone elements. While dynamic elements work to some
level, their high frequency response is quite poor. That's why many dynamic microphones often sound quite
muffled. “LoudMouth” was designed to take advantage of the wide and flat frequency response of condenser
microphones. Since condenser microphones require a small amount of power to operate, “LoudMouth” supplies
that needed power to the microphone without the need for additional wires in the microphone cord. No microphone
battery is required. “LoudMouth” uses operational amplifier technology to give you the highest quality audio. High
gain and extremely low distortion combined with a single-pole filter gives your radio a power-packed audio punch
with exceptional clarity
