Bass Boost Switch
This switch is used to accentuate the bass frequencies by adding +12 dB of boost to the signal (at 45Hz), or +18 dB of boost (@ 60Hz). Use the +18 dB @ 60Hz for maximum SPL (Sound Pressure Level).

Once the correct setting is found, this control should not

3Sub-sonic Filter Selector Switchrequire any further adjustment.

This switch enables On/Off selection of the sub-sonic frequency filter, thereby allowing the operator to initially set the amplifier high pass frequency for a sub-woofer between 20Hz and 50Hz.

In the "OFF" position of the switch, the response is flat and unaffected so the entire woofer audio frequency range (low-pass) is reproduced by the amplifier. Use this setting if the amplifier is being used to power a full range woofer speaker.

In the "ON" position, only the frequencies above the frequency set by the SUB-SONIC FILTER FREQUENCY (Hz) Control will be amplified and fed to the speakers. Use this setting to eliminate possible destructive sub-sonic frequencies (<20Hz). Setting should be at lowest frequency reproduced by your specific sub-woofer.

Fuse

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 the amplifier. If fuses blow consistently, carefully check all electrical
