type of application, the 'font fill' amplifier and speakers see no low bass material.
Cone distortion is drastically reduced, while efficiency is vastly increased.
D. Subwoofer Amplifier Gain
This control provides gain to the 120-watt mono subwoofer amplifier.
Accentuation or attenuation of +-12dB is possible with this control. The purpose
of this control is to adjust the output of the subwoofer system relative to the
efficiency of the main speaker system.
E. Master Gain Control
This control is found on all Linear Power™ amplifiers. The master-gain control
matches the output of any deck to the input of the 2121

if minimum gain. Proper adjustment procedure is found under
OPERATION/ADJUSTMENT.
F. 120 Watt Mono Subwoofer Output
To the Bass Vent
or any other dual speaker subwoofer system, Grey= right (+),
©
Green= left (+), Black is ground. The mono output amplifier is internally
paralleled to see a two-ohm load when used with two, four-ohm drivers. This
is done for higher current capability, and superior woofer control. For single
subwoofer use, connect both the green and gray wires to the speaker (+) and
both black wires to speaker (-). The ideal configuration is two, 4-ohm woofers.
When connected to a single four-ohm woofer full power will not be developed.
G.120 Watt Stereo Output
Grey = right (+), Green = left (+), Black = ground.
H. Low level Outputs
In bi-amp or tri-amp operation low level output (at unity gain) is always provided.
In the bi-amp mode output from the selected subwoofer crossover point to
beyond 20KHz is provided to the output plugs. In the tri-amp mode, output is
provided above the selected crossover point of the high pass filter to beyond
20KHz.
