Phase inversion on microphone inputs

MONO inputs assignable as EXT source

Ducking / AutoFader assignable to all sources (automatic attenuation of music on speech)

Automix

Automix feature simplifies mixing activities in the presence of many guests in the studio.

The function adds, to the existing sources, a new source called Automix, which is the sum of all enabled microphones.

The Automix source has all the features of a microphone source such as:

Studio/Control Room loudspeakers control

Studio/Control Room light control

Can be used as audio in Private mode for phone calls

Using this new source, the user can manage in a very simple manner all the microphones of the studio with a series of benefits:

Just 1 fader for the management of studio microphones;

A dedicated AGC section for each microphone input automatically adjusts the correct level;

Automatic management of attenuation on microphones not in use, simulating a slight closure of the fader;

Final compressor that allows an automatic leveling of the Automix source;

Possibility to use the microphones individually.

This feature further simplifies the work of the mixer engineer, even in the case he/she is also the host of the show.

Available settings in the Automix menu:

MIC-1    ON/OFF

MIC-2    ON/OFF

MIC-3    ON/OFF

MIC-4    ON/OFF (only for consoles with 5 Mic)
