by placing them next to the front left and right speakers, in both front corners or one in the corner and one 1/3 of the way along the front wall
from the corner. Each room is different. Experiment with these options or try other locations until you get the best results. If you must choose a
less-than-ideal position, the output level of Phase Technology powered subwoofers is adjustable to compensate for your listening environment.

The following instructions apply whether you are using a separate amplifier or Home Theater receiver. For simplicity we will use the term
"amplifier" throughout this manual to mean both.

[SUBWOOFER CONNECTIONS]
OPTION 1: LOW LEVEL SETUP This is the recommended method for those amplifiers and receivers that are equipped with a "Subwoofer
Out" or "Pre-Amp Out" connection. Virtually all audio/video receivers have this connection clearly marked on the rear panel. Run a dedicated
interconnect cable with RCA connectors from the subwoofer output jack to the line input on the subwoofer. In this setup, you will be using
the internal crossover on your processor.
Special note: Turn off and unplug your amplifier before connecting speakers.
Special Note: Observe Speaker Polarity Carefully!
Every cable, speaker and amplifier is clearly marked to show their positive (+) and negative (-) terminals. Amps and speakers
may use some combination of these symbols and/or colors to indicate positive (usually red) and negative (usually black or
white) connections. One strand of your cable will also be ridged and/or marked with a colored line or other indicator on the
positive side. For proper polarity and, thus, ideal system performance, always connect the positive side of the cable to the
positive terminals on your speakers and amplifier and the negative side of the cable to the negative terminals.

CAUTION
1. Power ON/Auto/OFF: This switch, when left in the "Auto" position,
automatically activates the subwoofer when an audio signal is detected and
shuts the subwoofer off after approximately ten (10) minutes of silence.
2. Subwoofer Level Control: Adjusts the volume of bass energy allowing
you to customize overall tonal balance to your individual room acoustics and
personal taste.
3. Crossover Frequency Control: This adjustment varies the point at which
the subwoofer takes over the task of creating low bass frequencies from
the rest of the audio signal permitting additional fine tuning of the total
system. A little experimentation with this control will allow you to match
the performance of the subwoofer to the rest of your speakers resulting in
extraordinary, accurate, deep bass response. This control should be turned
to its highest setting when the sub is connected through the Subwoofer out
on your receiver.
4. Phase Control: This adjustment matches the phase - the in and out
movement of speaker cones - to that of your main speakers. Adjust this
control by listening to music with bass content. The setting is correct when
the bass sounds the fullest.
5. High Level Input and Output: Used for direct speaker connections from
the left and right front speaker outputs when a low-level subwoofer output
is not available.
6. Low Level Input: Used from pre-out or Subwoofer-out.
