4.2.2 Audio Output – Auto-Mix
When the Mix operation mode is selected, an auto-
Mix feature is proposed. With a one-click operation,
the transition between two sets of sources can be
done at the same time, with fade-in-time and fade-
out time controlled by a slider.
All the channels that have the Auto-Mix checked will
fade between Source A inputs and Source B inputs.
Refer to the picture below for a description of the
three available mixing modes:
In the example shown to the right, a stereo source is
present on inputs A1-Ch8 & A1-Ch9, and a mono
source on A1-Ch10.
• With the A selection the stereo source passes
with 0 dB gain and the mono signal is muted.
• With the B selection the stereo source is
attenuated by 20 dB and the mono source
passes with 0 dB gain.
The transitions are smoothed by the controlled fade-
in and fade-out time.
