| Audio signals | Control signals | Description |
| Single input single output mono-mono | n/a |
Mono output obtained from the single mono input multiplied by the single gain (no mixing, just amplification) |
| Single input single output mono-stereo | n/a |
Stereo output obtained from the single mono input multiplied by two separate gains (no mixing, just amplification and routing) |
| Single input single output stereo-mono | n/a |
Mono output obtained by summing the channels
of the single stereo input
after multiplying each by a separate gain
|
| Single input single output stereo-stereo | n/a |
Stereo output obtained from the
single stereo input multiplied by a separate gain for each channel (no mixing, just amplification and routing)
|
| Double input single output mono-mono | n/a |
Mono output obtained by
summing the
double mono inputs,
after multiplying each by a separate gain
|
| Double input single output mono-stereo | n/a |
Stereo output obtained by
multiplying the double mono inputs by a separate gain,
then routing them
to the left and right output channels, respectively
(no mixing, just amplification and routing)
|
| Double input single output stereo-mono | n/a |
Mono output obtained by summing
all four channels corresponding to the double stereo inputs,
after multiplying each by a separate gain.
| Double input single output stereo-stereo | n/a |
Left channel output obtained by
summing the left channels of the double inputs,
after multiplying each by a separate gain.
Right channel output obtained by
summing the right channels of the double inputs,
after multiplying each by a separate gain.
