Power Microphones
Power or pre-amplified microphones require a battery and amplify the audio before it gets to the radio. This is useful for those who speak softly or may have a weaker signal. These microphones can be identified by a volume knob on the microphone (usually on the back) and/or a battery compartment. The battery can be accessed either by a slide-open compartment, or by opening the shell for the microphone.
