This audio component allows mixing of various microphone signals in a simpler and more efficient way, helping the technician and avoiding continuous level adjustments. The most frequent uses are for boardrooms, plenary sessions of town halls, churches and, in general, for applications where there are more than one microphone and several people in conversation associated or not with a sound reinforcement system.

The effect is also highly regarded as a -talk-over- for speakers, presenters and DJs with background music. The system will reduce the music level in time with the increase in the voice level and vice versa.

Defining a precise gain setting increases the system's intelligibility and margin against coupling. This task is carried out by the MAP in a simple and effective way.

The method used within the MAP processor is called gain distribution or shared gain. The installer defines a total gain level for all microphones in the system and the MAP will distribute the available gain among them, giving more gain to those microphones that show more activity (higher signal) and less gain to those with less activity. In other words, the person who is not speaking gives part of their microphone gain to those who are speaking louder.

This method improves stability by reducing or canceling the mics that are not used as the sound technician would. As an extra profit is not introduced, but what there is is distributed, the system will not have a tendency to couple.

The total gain available in a system is a constant dependent on the polar distribution of the microphones, the frequency response of the speakers, speaker microphone distance, angles, etc. and must be taken into account and adjusted with certain safety margins.

Available Automix settings:

• Attack: Defines the reaction time to fire the Automix, avoiding false shots.
• Release: Defines how long the Automix continues to act after the signals drop below the level.
• Ratio: Defines the working point of the Automix. Progressive adjustment from 1: 1 (no effect), at a 2: 1 ratio (where two equal signals are reduced by 6 dB each), to a 3: 1 ratio (where 2 equal signals will be reduced by 12 dB). The recommended setting to start with is 2: 1.
