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 clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise.

•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.

•If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise.

Input Switch

It is possible to input from a car stereo external output (subwoofer output) or a car stereo speaker output. When using an external output (subwoofer output), slide the switch to the left. For connection instructions, see the “Connection Diagram” section. When using a speaker output, slide the switch to the right. In this case, it is necessary to use the supplied speaker input wire with RCA pin cord. For details, see the “Using the Speaker Input” sec- tion.
