37. OUTPUT POWER
The Output Power switch is an eight-position switch that
determines the output power limit of the amplifier. This
allows you to control the overall system volume level, and
also to determine the overload point of the power amplifier.
The eight switch positions are labeled 120, 60, 30, 16,
8, 4, 2, and 1 Watts. As the output power setting is de-
creased, the overall volume decreases accordingly and
the power amplifier response becomes "spongier," in the
same way that a low-power vacuum tube output stage
responds when driven hard.
38. MAINS Switch
Use this to turn the amplifier on and off. The cool blue
light next to the switch lights when the amplifier is on.
