8) FRONT “Q” Control
Once the FRONT highpass crossover point has been determined, use the
FRONT “Q” control to increase the bass information centered around the
crossover point.
Setting the front “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;
lowering the “Q” input sensitivity or raising the highpass crossover point will
eliminate this. Minor adjustments to each setting are required to fine-tune the
system.
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—Full-range Speakers (cont.)
9) REAR Input Sensitivity & Crossover Controls
Setting levels for the rear channels proceeds the same as for the front except
for the elimination of the “Q” control settings. Crossover selector switch must
be set to “HP” and filter switch must be set to “ON.” If the loudspeaker being
used is capable of full-range operation, filter should be set to “OFF.”
Setup Tuning—Rear Fill Speakers
You may set the rear channels for summed mono operation from the L & R REAR RCA inputs by setting the
REAR INPUT switch to the right-hand MONO position and then connecting the L & R REAR loudspeakers
normally as you would for regular stereo operation. This configuration is beneficial for rear fill in some appli-
cations.
Setup Tuning—Subwoofers
1) SUBWOOFER LEVEL Control
Refer to subwoofer level control in owner’s manual. If the control is not used, SUBWOOFER LEVEL switch
must be set to “OFF.”
2) REAR Input Switch
Move switch to the right-hand (MONO) position, the inputs are summed to mono. Connect the subwoofer
to the REAR SPEAKER OUTPUT terminals marked for MONO operation. NOTE: Subwoofer impedance is
2 ohms minimum.
