and/or amplifier.

Mode

The Mode control switch toggles the input mode of the amplifier
between 2 channel and 3 channel operation.

• When set to 2CH, only input channels 1 and 2 will be active.

• When set to 3CH, all input channels will be active.

HPF (High Pass Filter)

The HPF (adjustable between 40Hz and 400Hz) filters out frequencies
below the designated setting on the amplifier while attenuating
frequencies above that setting.
