1. Turn the
Subwoofer Level
control completely counter-clockwise to
its minimum;
2. Turn the
Subwoofer Cut-Off Frequency
control to
’Bypass’
;
3. Set the
Phase Switch
to 0°;
NOTE:
When using receivers with Automatic Level and Crossover
setting systems such as Anthem’s ARC system, the Volume Level
should be set to ‘Detent’ (center), Phase should be set to ‘0’ and
Crossover set to ‘Bypass,’ then skip the next four steps.
4. While you listen to a selection in your primary listening area, have an
assistant turn up the
Subwoofer Level
control until the subwoofer
can be clearly heard;
5. Have your assistant try the
Phase Control Switch
in both positions
until you determine which one delivers the most bass. Your subwoofer
and front speakers are now ‘in phase.’ Do not change phase switch again
unless you move your subwoofer or front speakers;
6. Turn the
Subwoofer Level
control completely counter-clockwise to
its minimum;
7. Turn the
Subwoofer Cut-Off Frequency
control completely counter-
clockwise to 50 Hz;
8. Slowly rotate the
Subwoofer Level
control until you match the
subwoofer output level with the level of your front speakers. Bass
should be clearly audible, but not intrusive;
9. Slowly rotate the
Subwoofer Cut-Off Frequency
control until you
hear the best subwoofer/main speaker blend. If the sound is too ‘thin,’
you have not set the frequency high enough; if the sound becomes
‘boomy’ you have set the frequency too high. Adjust until you find the
most natural balance.
