SUBWOOFER PLACEMENT
Subwoofer placement is important, but less critical than speaker placement, because the frequencies subs
reproduce are omni directional. This means the human ear doesn’t perceive these low frequencies as coming
from a specific direction, enabling placement of a subwoofer virtually anywhere in the listening room.
It’s best, however, to keep a subwoofer within the sound field of the other speakers. The closer the subwoofer is
to a wall, the louder and more intense its bass output will be: this effect is even stronger when the sub is placed in
or near a room’s corner. If using two subwoofers, start 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 and 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.

SUBWOOFER AMPLIFIER PANEL
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.
