4. X-OVER Switch
When switched to LPF this control engages the units Low Pass electronic crossover circuitry. The LPF setting
should be selected with using this as a bass amp only for the subwoofer(s). The FULL position defeats the
crossover and allows the full range of frequencies present at the inputs to feed the amplifier.
5. LPF (Low Pass Filter) Control
This filter allows low pass of frequency and is adjustable from 40Hz through 250Hz to eliminate unwanted
high frequencies.
6. BASS EQ Control
This equalization circuit is used to enhance the low frequency response of the vehicle’s interior. With up to
18dB of boost centered at 45Hz, the BASS EQ can be adjusted to meet your own personal taste.
7. REMOTE Gain (RJ45 Jack)
This is the connector port for the Remote Level Control. Now the amplifiers secondary gain circuit can be
adjusted from the driver’s seat.
8. BADGE Switch
Controls the lighting of the top mounted PowerBass logo badge.
9. POWER/STATUS Indicator
The BLUE L.E.D. lights up when the power is on. This L.E.D. turns RED constantly or flashes when the built-in
protection circuitry is activated. This indicates a problem with the system in relation to the amplifier (see
Troubleshooting Tips).
10. SPEAKER Output Terminals
As shown in the wiring diagrams, be sure to observe speaker polarity through the system and speaker imped-
ance. This specially tooled terminal is designed to accommodate up to 10 gauge speaker wire.
11. FUSES
For convenience most PowerBass AutoSound amplifiers utilize common automotive ATC type fuses. For
continued protection in the event that a fuse blows, replace the fuse only with the same value.
CAUTION: These power fuses on the amplifier chassis are for protecting the amp against over-
drive. To protect the vehicles electrical system, an additional fuse should be used within 18-inch-
es (45cm) of the battery on the 12V+ cable.
