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.
