Setting the Unit
Power Indicator
The power indicator lights when the power is switched on.
8.1 OPERATIONS
Gain Control
If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the front of the power amplifier clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise.

8. OPERATIONS AND SPECIFICATIONS
BFC (Beat Frequency Control) Switch
If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.
· When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level.
LPF (Low-Pass Filter) Select Switch
Set the LPF select switch as follows according to the type of speaker that is connected to the speaker output connector and the car stereo system: LPF Select Switch
LPF (left) OFF (right)

Connection Diagram
Fuse (30 A) Special red battery wire [RD-223] (sold separately) After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Fuse (30 A) Ground wire (black) [RD-223] (sold separately) Connect to metal body or chassis.
Grommet
Connecting wires with RCA pin plugs (sold separately).
Car stereo with RCA output jacks
External Output
Front side
RCA input jack
Back side Fuse (25 A) × 2
Speaker terminal
System remote control wire (sold separately) Connect the male terminal of this wire to the system remote control terminal of the car stereo (SYSTEM REMOTE CONTROL). The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch.
