3 Filter Selector

This switch allows selection of the frequency filters that permit the amplifier to be used to reproduce the entire audio range, just the bass, or all frequencies above the bass range.

In the "OFF" 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 "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 amplifier is 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 amplifier is being used to power the full-range speakers in a system that also has separate sub-woofer(s).

4 Crossover Frequency Control

This Control selects the crossover frequency when the Filter Selector is in the "LOW-PASS" or "HI-PASS" settings. Adjust it to the appropriate position for the characteristics and crossover frequency requirements of the speaker system with which the amplifier is being used.

5 Bass Boost Switch

This switch is used to accentuate the bass frequencies by adding 8 dB of boost to the signal (at 45 Hz.).

6Fuse

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 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.
