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 "Y-adapter" when using the
amplifier in a bi-amplified or 4-Channel mode.
This switch enables you to easily invert the phase of the
Rear channels on the amplifier without having to discon-
nect the speaker wires. See the wiring diagram on page
17 for use.
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.
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.
