Yamaha MC802 - Manual (Page 7)

Channel Fader
This is the main level control for each input channel. It determines the level of the signal sent
from the corresponding input channel to the master stereo buss. The settings of the input
channel faders determine the "mix" or balance of sound levels between the instruments or
other sources connected to the inputs.
* If a channel is not being used, its fader should be set to the minimum position to prevent
unwanted noise from being added to the main program signal.
