HPF (High Pass Filter)
The HPF (adjustable between 40Hz and 400Hz) filters out frequencies
below the designated setting on the amplifier while attenuating
frequencies above that setting.
Gain
This control is used to match the input sensitivity of the amplifier to the
radio. The Gain Control is not a volume control. Use the source unit
(radio) to control system volume. Use these steps to properly set all three
Gains:
A. Set the Gain Control to minimum by turning the
control knobs completely counter clockwise.
B. On the radio, set the bass and treble to zero, and adjust
the volume to approximately 2/3 of maximum.
C. Slowly increase the amplifier’s Gain by turning the knob
clockwise until the sound has just begun to distort. Then turn
the knob counterclockwise until the distortion goes away. This
will allow the amplifier to operate at maximum efficiency.
Failure to follow these steps could result in damaged speakers
and/or amplifier.
Bass Boost
The Bass Boost increases the decibel level of the bass at 50Hz. The Bass
Boost control adjusts between 0dB (no boost) and 12dB (maximum).
