Input Combine
Your multi channel
POWERCLASS
™
amplifier can use both front
and rear outputs from your head unit to maintain the ability to fade
front to rear, or you can run a single set of RCAs to the front inputs
and push in the COMBINE switch on the amplifier end plate to route
the front signal to the rear channels as well.
Adjusting The Amplifier Input Gain
1. Adjust all amplifier input gain controls to just above minimum
sensitivity (fully counterclockwise).
2. Using the cleanest source (CD), with music playing turn up
the head unit until you can hear distortion. Now turn it down a
bit until you cannot hear the distortion.
3. Increase the Amplifier gain (clockwise) until the onset of
audible distortion. Then decrease the gain to the point just
before the distortion starts. This setting minimizes background
noise and prevents overload.
4. Repeat step 3 for any remaining amplifiers in the system.
Heatsink Cooling
The unique heatsink on your
POWERCLASS
™
amplifier has
been designed with fins on the inside of the aluminum mass.
This allows for the transfer of heat from the circuitry to the
heatsink fins and out through the vents in the endplates. Be
sure you have ample space around the amplifier for cooling,
at least 2" on all sides.
