Signal flow of the mixer
Mixer basics
A mixer accepts audio signals and modifies them, then mixes them.
The following diagram shows how the input signals flow through the mixer section of the LM16.
As the diagram indicates, an analog signal from the [INPUT] connector is level-adjusted by the
[TRIM] control and converted to digital, then sent to the channel fader via the EQ.
After the channel fader, the pan control adjusts the left and right (or odd and even) balance of
signal sent to stereo left and right busses (or odd and even group busses).
Then the stereo signal is finally level-adjusted by the [STEREO] fader and output from the [STE-
REO OUT (L, R)] connectors.
A buss sums signals and mixes them. In the diagram below, busses are shown as pipes.
The LM16 provides the following eleven busses: stereo busses (L, R), group busses (1, 2, 3, 4), AUX
busses (1, 2, 3), effect buss and solo buss. Each buss sums signals. The mixed signal may be D/A
converted and fed to an external device, or directly fed to the internal effects.
