LEVEL CONTROL
This control is used to match the input level of the amplifier to the output level of you head unit. We recommend the
following method. NOTE: Remove screws and the top cover of amplifier to access controls.
3. Adjust the level control until the desired maximum
volume is achieved without distortion.

damage to the audio system.
1. Turn the amplifier level to zero
2. Turn the volume of the head unit to and the bass
and treble to zero
