If, however, there is still output from the amplifier when
the car stereo volume control is at its minimum setting,
or the output level increases too fast with a small
rotation of the volume control, adjust the Level control
to decrease the output from the system.
Once the correct setting is found, these controls should
not require any further adjustment.
Sub-Woofer Crossover Selector
This switch allows selection of the frequency filters that
permit the amplifier to be used to reproduce the entire
audio range or just the bass range.
In the "FULL" position of the switch, the response is
flat and unaffected so the entire audio frequency
range is reproduced by the amplifier. Use this setting
if the amplifier is being used to power a full range
speaker system.In the "LPF" (Low-Pass Filter)setting,
only the bass frequencies below the frequency set by
the Crossover Frequency Control will be amplified
and fed to the speakers. Use this setting if the
amplifier is being used to power a sub-woofer speaker
system.
LPF Crossover Frequency Control
This Control selects the crossover frequency when
the Sub woofer Crossover Selector is in the
"LPF" setting.Adjust it to the appropriate position for
the characteristics and crossover frequency
requirements of the speaker system with which the
amplifier is being used.
HPF Crossover Frequency Control
This Control selects the crossover frequency when the
Sub woofer Crossover Selector is in the "HPF" setting.
Adjust it to the appropriate position for the characteristics
and crossover frequency requirements of the speaker
system with which the amplifier is being used.
Bass Boost Frequency Control
Allows the addition of up to +18dB increase in sound
level in lower frequencies (0~18dB).

Fuse
The circuitry of the amplifier is protected from damage by
an automotive-type fast-blow fuse. If fuse replacement
is necessary, use only fuses of the of the same ampere
rating as originally supplied with the unit. The use of fuses
with incorrect ratings may cause serious damage to the
amplifier. If fuses blow consistently, carefully check all
electrical connections to the unit.
