TUNING THE AMPLIFIER
SETTING THE GAIN (LEVEL):
The gain control is designed to help match the input sensitivity of the
amplifier to the output voltage of the source unit. To set the gain, start
by turning the gain all the way down then turn up the source unit up to
3/4 volume. Slowly raise the gain until audible distortion is apparent
then back the gain down slightly until the distortion can no longer be
heard. For most users setting the gain up half way will achieve the
desired results.
*IMPORTANT NOTE
The gain dial is not a volume control and if set too high it will also
amplify any noise or distortion already present. This can potentially lead
to clipping.
SETTING THE BOOST SELECT:
The Bass Boost switch will increase the power output at 45Hz for more
pronounced bass. There are three setting for Bass Boost 0db, +6db and
+12db. Exercise caution when using this setting. We recommend 0db,
but if Boost is required start at +6db and listing for audible distortion
before increasing the Boost to +12db.
SETTING THE INPUT SELECT
2-CHANNEL OPERATION
If your source unit has one set of pre-amp outputs (RCAs), set the
switch to 2-channel input. The signal will be summed to all channels.
This is ideal for source units with 1 pre-out or when bridging channels
1&2, 3&4.
4-CHANNEL OPERATION
If your source unit has two pairs of pre-amp outputs (RCAs) front and
rear/sub, set the switch to 4-channel input. This will send signal to all
4-channels and retains fader and balance control.
3-CHANNEL OPERATION
If your source unit has one pair of pre-amp outputs (RCAs) front or
rear. This is ideal when using one pair of speakers on channel 1&2 and
bridging 3&4 to a center channel or subwoofer.
