from the system. 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.

5LPF Crossover Frequency Control

This Control selects the crossover frequency when the Sub woofer Crossover Selector 4 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.

4Crossover 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 5 will be amplified and fed to the speakers. Use this setting if the amplifier is being used to power a sub-woofer speaker system.

HPF(High-Pass Filter): Only mid-high tone (50Hz-250 Hz) Speaker.

6High Level Input Connection

If the car stereo not does not provide low-level outputs, the amplifier may be connected via the speaker (high- level) outputs from the stereo. Wire the speaker leads from the car stereo to the 5-pin adaptor harness as shown in the diagram (shielded cable is not required for this application) and plug the connector into mating High- Level Input socket on the amplifier. Carefully splice and insulate all wire connections.

7Fuse

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.
