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 frequen
