Setting Channel Levels
The A275 features independent
Level Adjustment Potentiometers for each of its two channels. Use a small Phillips screwdriver to inde-
pendently adjust each channel of the amplifier for the specific speakers and environmental conditions of the area it is powering. Turning
the potentiometer clockwise increases the level, while turning it counter-clockwise decreases the level. Factory default is 85%.
Set the levels by first lowering them all the way down, then raise the volume of any keypads or volume controls to maximum. Slowly
increase the level of the channel being adjusted by turning the potentiometer clockwise until the channel begins to distort, then reduce the
level slightly (turn counter-clockwise) until distortion is no longer present. Follow this procedure for each channel.
