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.
Connecting to Speaker Level Outputs
The least desirable connection is to connect to the stereo speaker outputs on your
amplifier using a pair of speaker wires (not included). Perform the following steps to
connect the subwoofer to speaker level outputs on your amplifier.
1. Power off and unplug all equipment to be connected.
2. Using a speaker wire (not included), plug one end into the SPEAKER LEVEL IN L
input, then plug the other end into the left channel speaker level output on your
amplifier. If your amplifier has more than 2 speaker outputs, use the main or front
speaker outputs. Take care to ensure that polarity is properly maintained. Repeat
using a second speaker wire (not included) for the R channel.
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.
