LEVEL CONTROL
This control is used to match the input level of the amplier to the output level of you head unit. We recommend
the following method. NOTE: Remove screws and the top cover of amplier to access controls.
3. Adjust the level control until the desired
maximum volume is achieved without
distortion.
4. Failure to follow these steps may cause
permanent damage to the audio system.
1. Turn the amplier level to zero
2. Turn the volume of the head unit to ¾ and the
bass and treble to zero
