Radio/Television Announcer Position
The MM-1 is used as a microphone preamplifier for an announcer’s microphone and can pass a mix-
minus headphone feed to the announcer. Sending a line level signal from the announcer position
to the main mixing console is preferred over sending a mic level signal. When engaged, the limiter
prevents distortion during shouting and high microphone signal levels.

In the set-up above the announcer has level control in the headphones of their overall audio level
and the level of the mix-minus feed.

microphones locally greatly improves the reliability and audio quality of a podium mic feeds. The
microphone is connected directly to the MM-1, which provides gain, microphone power, filtering,
and limiting. In addition, the microphone signal can be verified using the headphone output of the
MM-1.
