Vanguard DA SERIES - Amplifier Functions and Operation; Channel Level and Input Controls; Power Mode Selection; Bridge Mode Operation

FUNCTIONS
Level Controls - Allows any of the channels to be adjusted independently to raise or lower the output of each channel.
R R+L L Switch - When BUS input is selected, this switch is used to direct the channel to play the le signal from the input “L” or the
right signal from the input “R”, or combined right and le signal from the input “R+L”.
BUS*LINE Switch - Allows each channel to play a variety of different inputs. Depending on the switch posion the channel amplifies
the signal connected to the BUS input and its own LINE input.
