11.Preamp-Output Crossover Switch – This switch controls the built-in crossover that is directed to the preamp-output connectors. Set the switch to “Flat” for full band operation. Set this switch to “Low-Pass” to activate the low- pass filter on the preamp output (for subwoofer use). Set the switch to “High-Pass” to activate the high-pass filter for use with satellite speakers.

12.Speaker Output Crossover Switch – This switch controls the built-in crossover that is connected to the power amplifier circuitry. Set the switch to “Flat” for full band operation. Set this switch to “Low Pass” to activate the low

pass filter on the amplifier (for subwoofer use). Set the switch to “High Pass” to activate the high pass filter for use with satellite speakers.

13.Input Mode Selector – This switch is used to set the input mode for both preamp and speaker-level inputs.

Set this switch to Stereo for normal operation using both left and right inputs. Set this switch to R to drive both the left and right output channels with only a single input on the right channel. Set this switch to “L+R” to sum the left and right inputs for a mono output on both amplifier channels. Power Indicator LED (on chassis top) – LED steadily illuminates for normal operation. LED blinks when protection circuitry or muting is engaged.

14.Bass Boost Switch – This activates a built-in Bass Boost circuit used to increase low-bass output.
