2. LINE IN/SUB IN: The two RCA jacks accept a line level signal from the
preamplifier output of a receiver or preamplifier. Use both jacks when
connecting a stereo preamplifier output. Use the L channel input when
connecting to a mono LFE subwoofer output.
3. PHASE: Depending on the location of the subwoofer, the sound that reaches
your listening position may be out of phase with the sound from the rest of the
system. If the bass sounds out of timing, muddy, or attenuated, try flipping the
phase switch to the other position. The default, which will provide the best bass
sound most of the time, is with the phase switch set to 0°.
4. LOW-PASS FILTER: The rotary control sets the upper frequency for the
subwoofer to handle, from 40-150 Hz. Initially, you should set the LOW-PASS
FILTER to the lower frequency for the main speakers, then adjust it until the
sound from the subwoofer blends in with the sound from the rest of the system.
5. VOLUME LEVEL: The rotary control adjusts the overall volume level of the
subwoofer. For best results, the subwoofer volume should be set to where it
seamlessly blends in with the sound from the other speakers.
6. SPEAKER LEVEL IN: If your amplifier or receiver does not have a stereo
preamplifier or mono LFE output, you can connect to its speaker output. This is
the least favored method of connecting the subwoofer.
7. 120V - 60Hz 1.0A: Plug the AC power cord into a nearby AC power outlet. The
subwoofer accepts a nominal 120 VAC, 60Hz power source.
