Operation Manual

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.
