Adjustments
1. Set to the "H.P.F" position when the amplifier is used to drive a tweeter/midrange system. The
frequencies below the crossover point will be attenuated at 12dB/octave. Permits adjustment
of the crossover frequency ,by rotating the knob to select any frequency between 60Hz to 1.2KHz
as the crossover point.
2. Set to the "L.P.F" position when the amplifier is used to drive a subwoofer. The frequencies above
the crossover point will be attenuated at 12dB /octave. Permits adjustment of the crossover
frequency, by rotating the knob to select any frequency between 50Hz to 250 Hz as the crossover
point.
3. Set to the "OFF" position when the amplifier will be used for driving full-range speakers. The full
frequency bandwidth will be output to the speakers without high or low frequency attenuation.
4. Level adjustment-The sensitivity adjustment is to allow the amplifier to work with many different
brands of head units. It allows input signal to vary between 350 millivolts to 5 volt from the head
unit or other signal processor. Start by setting the sensitivity adjustment to the "MIN" (3 volts).
Using a cassette or compact disc that you are familiar with ,turn on head unit to the 3/4 volume
setting. Slowly turn up sensitivity adjustment towards the "MAX" (200 millivolts) using a flat head
screw driver. Stop turning on the onset of distortion and turn back just a slight. The 3/4 volume
setting is now the "maximum" volume for the head unit. The goal is to keep the level control to the
lowest setting yet still have enough signal to drive the amplifier. This is done to prevent over driving
the amplifier and to keep system noise to a minimum. It is important not over drive speakers (at
point of distortion) this will cause permanent damage to the speakers. Also,
if the amplifier itself is over driven, it could be damaged.
