About AUTOMIXER

Automixer is included as a standard feature on the QL series. Automixer searches for enabled
mics and automatically optimizes gain distribution, for uses such as speeches without scripts.
This allows uniform system gain to be maintained among multiple mics, freeing the engineer
from making constant fader adjustments.
Automixer operating principle
3
With the Dugan speech system used in Automixer, you can automatically adjust the gain for
4
multiple mics used for speeches.

Gain (dB) in
Automix
When 1 person is speaking, the gain on the mic
being used is immediately increased and the gain
on all other mics is reduced. The same operation
occurs even if another person is speaking.
The Dugan speech system functions differently from a limiter or auto level controller. When
multiple people are speaking, the engineer can adjust each level using the faders as normal.
Even if nobody is speaking, the system searches for mic audio and automatically distributes
gain. Therefore, faders can leave in their raised positions.

If 2 people are speaking at the same time, gain is
automatically distributed so that the total gain is
consistent across both mics, and the gain on the
remaining mic is reduced.
