LEVEL SEmlNG
The input levels are adjusted by means of the input level controls located on the
front of the amplifier. This is a unique dual-stage circuit that adjusts both level and
gain. This topology maintains better S/N Ratio even when using sources with
minimal output.
In the ideal situation, all components in the audio system reach maximum undistorted
output at the same time. If you send a distorted signal to an amplifier, it is simply
going to amplify distorted information. The same holds true if an outboard proces-
sor or crossover begins to distort before you have maximum output from the ampli-
fier. By setting all components to reach clipping at the same time, you can maxi-
mize the output of your system.
For the
RUBICON
amplifier, follow these steps for
setting the input levels:
1.
Turn the amplifier’s input levels to minimum position (counter-clockwise)
,

2.
Set the source unit volume to approximately
3/4
of full volume.

While playing dynamic source material, slowly increase the amplifiers’ input
,
level until a near maximum undistorted level is heard in the system.
FRONT SPOILER
Once the amplifier is installed and the
proper levels set, place the front spoi

position, and secure it using the suppl
ied
hardware.
