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 a Stereo Preamplifier Output
The next best type of connection is to connect to the stereo preamplifier output on an
amplifier or receiver using a stereo RCA cable (not included). Perform the following steps
to connect the subwoofer to a stereo preamplifier output.
1. Power off and unplug all equipment to be connected.
2. Using a stereo RCA cable (not included), plug the connectors on one end into both
LINE IN/SUB IN L and R inputs on the subwoofer, then plug the other end into the
stereo preamplifier outputs on your amplifier. Because the subwoofer is
monophonic, there is no need to match left and right channels.
Note: If you are using an external power amplifier and your preamplifier has only a
single preamp output, use RCA Y-cables (not included) on each output to allow
both the power amplifier and the subwoofer to be connected to each output.
