Front/Rear Input Switch
This switch allows you to use the front input to drive both Front and Rear channels. Switching to Rear position allows you to run separate Front and Rear inputs. This eliminates the need for a
0/180° Rear | This switch enables you to easily invert the phase of the |

Treble/Bass These controls adjust the amount of treble and bass response desired. To increase the amount of response, turn the controls clockwise; to decrease, turn the controls counterclockwise. Note that there are separate Bass and Treble controls for Front and Rear channels.
Input Gain Controls
These controls are factory preset to 500 millivolts to match most head units and are variable from 100 millivolts to two volts. (More than likely they will not need adjusting.)
If just a little volume from the source unit drives the amplifier into distortion, reduce the input gain controls so that the distortion doesn’t start until the source volume is at about 3/4 of its rotation. Note that there are separate Front and Rear gain controls.
