Max Mixer Lvl
Sets the maximum input level of the mixer according to the amplitude of the signal.
Remarks:
For the high-level input signal, select a smaller maximum mixer level to increase
the input attenuation and reduce the distortion of the signal; for the low-level
input signal, select a larger maximum mixer level to reduce the input attenuation
and noise.
You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,
