8) “Q” Control
Once the highpass crossover point has been determined, use the “Q” con-
trol to increase the bass information centered around the crossover point.
Setting the “Q” control is done in conjunction with setting the levels on the
input sensitivity and highpass crossover frequency controls. You may find while
setting the “Q” that bottoming may be detected in the front speakers; low-
ering the “Q” input sensitivity or raising the highpass crossover point will elim-
inate this. Minor adjustments to each setting are required to fine-tune the sys-
tem.
Setting the “Q” is a subtle process. It is recommended that the “Q” setting be left in the 0.7 position and
adjusted only after the input sensitivity and highpass crossover ranges are known. Small adjustments to the
“Q” setting are all that are required to fine-tune the system.

Setup Tuning—Rear Fill Speakers
You may set the channels for summed mono operation from the L and R RCA inputs by setting the
INPUT switch to the right-hand, MONO, position and then connecting the L and R REAR loudspeakers
normally as you would for regular stereo operation. This configuration is beneficial for rear fill in some
applications.
Setup Tuning—Subwoofers
1) Input Switch
Move switch to the right-hand (MONO) position; the inputs are summed to mono. Connect the subwoofer
to the SPEAKER OUTPUT terminals marked for MONO operation. NOTE: Subwoofer impedance is 2 ohms
minimum.
