3. Turn the VOLUME LEVEL and LOW-PASS FILTER knobs fully counter clockwise to the
minimum position.
4. Ensure that the POWER switch on the subwoofer is in the OFF position.
5. Plug the Power Cord into a nearby AC power outlet. The subwoofer requires a
nominal 120 VAC, 60Hz power source.
6. Plug in and power on all connected equipment.
7. Set the POWER switch on the subwoofer to the ON position.
8. Start playing audio material with significant low frequency content. Adjust the main
system volume control until it is at a comfortable listening level.
9. Slowly turn the VOLUME LEVEL knob clockwise until the bass content from the
subwoofer is at about the same volume level as the audio from your main speakers.
10. Slowly rotate the LOW-PASS FILTER knob clockwise until the low frequency content
from the subwoofer blends smoothly with the audio from the main speakers in the
crossover region. If the crossover frequency is set too high, the bass will sound
"boomy" and male voices will have an unnatural "chesty" quality.
SUBWOOFER POSITIONING
In most rooms, the optimum location for your subwoofer is in the closest solid front corner
or somewhere along the front wall in line with your front speakers. This location typically
offers optimal energy coupling with the room, front-speakers, and the deepest low
frequency extension, with the best high impact bass. Try to avoid a location that is far
away from walls or near the center of your room.
Bass output is maximized when the subwoofer is tucked into a corner. An ideal corner is far
from wall divisions and has at least 6 feet or more of wall to either side. Try to keep the
subwoofer placement away from any large openings into other rooms. When corner
loading a subwoofer, you might want to experiment with how close the subwoofer sits to
the closest wall, with a general rule of thumb that it should be within 1 foot.
Placing the subwoofer in close proximity to the seating position, for example, right next to
or behind the sofa, maximizes the output and can reduce room effects on the subwoofer.
