(b). The speaker fanout connector on the right, marked 'main/mid-bass', is the
stereo output.
Connect the GREY wire to the RIGHT speaker (+) terminal.
Connect the GREEN wire to the LEFT speaker (+) terminal.
Connect one of the BLACK wires to the RIGHT speaker (-) terminal.
Connect the other BLACK wire to the LEFT speaker (-) terminal.
DO NOT apply power to the system until the installation is complete, and the
following steps 1 and 2 have been performed.
1. Be certain that all gain controls on each component have been turned down.
2. Set all crossovers a point well within the defined frequency parameters of the
drivers. The speaker manufacturer will supply frequency response data with their
driver.
3. Apply power to the system. The Amp(s) will turn on after a slight delay. To
properly adjust the master gain control of the 2120
technique: Slowly turn the volume up on your source unit until you hear it just
start to distort, then back it down just below that point. That is a loud as you
should ever play it for quality sound. Now, slowly increase the master gain on the
2120 until either the speakers distort from excess power, or, the amp distorts
from input overload. At either point, slightly decrease the gain control on the amp
and a perfect input/output match has been achieved. After the master gain has
been properly adjusted, use the same procedure to adjust the sub-level control.
Some source units with extremely low output levels will require a LINEAR
POWER™ PA2
to boost the output to the necessary proper level.

NOTE: IT IS VERY IMPORTANT THAT THE GAIN CONTROL BE TURNED AS
FAR DOWN AS POSSIBLE IN ORDER THAT UNWANTED ENGINE NOISE BE
KEPT TO A MINIMUM.
Now that the gain controls have been properly set, the system is ready to be "fine
tuned". Always tune a multi-amp/driver system from the bass up. In a bi-amp
system, the subwoofer crossover should be varied until the smoothest low
frequency response has been obtained. Tri-amping is a more sophisticated
process of sound reproduction and hence requires more time to properly design
and fine tune. Keep in mind that a poorly designed tri-amplified sound system
may yield lower sound quality than a well executed bi-amped system.
