The gain control (input sensitivity) on this amp is not a volume control. It is designed to provide proper
matching of various source units to this amplifier, and provides a reference to how much signal will be
necessary to reach maximum operating power. Correct settings will ensure safe operation for both your
amplifierandspeakers.
