reproduced by the amplifier. Use this setting if the respective amplifier channels are being used to power a full range
speaker system.
In the "LOW PASS" 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 respective amplifier channels are being used to power
a sub-woofer speaker system.
In the "HI-PASS" setting, only the frequencies
above the frequency set by the Crossover Frequency Control will be
amplified and fed to the speakers. Use this setting if the respective amplifier channels are being used to power the
full-range speakers in a system that also has separate sub-woofer(s).
4 Crossover Frequency Controls
These Controls select the crossover frequency when the Filter Selector is in the "LOW-PASS" or "HI-PASS" settings.
Adjust them to the appropriate position for the characteristics and crossover frequency requirements of the speaker
system with which the respective channels of the amplifier are being used.
5 Bass Boost Switches
These switches are used to accentuate the bass frequencies by adding +12 dB or +18 dB of boost to the signal
(at 45 Hz.) on the respective channels.
6 Remote Subwoofer Level Control Input
This connector permits the amplifier to be used with an optional Remote Control Unit PAB-RC. The PAB-RC control
unit allows for adjustment of the bass boost gain level from the passenger compartment.
7 Fuses
The circuitry of the amplifier is protected from damage by automotive-type fast-blow fuses. If fuse replacement is
necessary, use only fuses 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.
