CAUSES and SOLUTIONS:
1. Make sure the head unit is off and its volume control is set to minimum. On SBP10AMP / SBP12AMP's top panel, initially set all controls to their midpoint positions, as shown in Figure 5. Turn on the head unit and play a favorite music track that has substantial bass. set the head unit's volume control to 75 percent of the total output (approximately 3 o' clock on rotary controls). Adjust the GAIN control clockwise until distortion is heard and turn it back a little.
8. Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste. NOTE: In most cases, the above steps will provide satisfactory tuning. [. . . ] Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste. NOTE: In most cases, the above steps will provide satisfactory tuning. However, the actual process may require several readjustments of each control, since the settings will interact with each other.
