Congratulations....
....for choosing Precision Acoustics Subwoofer. When used with your current Audio/Home-Theatre

today's music and film digital soundtracks.
This subwoofer has been designed to give you many years of trouble-free listening enjoyment.

STEP 1
™
Subwoofer Placement
Low frequency sound is generally non-directional. This allows for great flexibility in the placing of a
subwoofer, as it is difficult for the human ear to discern where the low frequency sound originates.
Ideally, however, the subwoofer will be placed on the same plane as the main left/right speakers.
STEP 2
Connecting The Subwoofer
A) Line Level Connection
(also knows as "Low-Level")
Connect the audio/video receiver or processor's
subwoofer output, to the Reference Audio Subwoofer's
line level input. (Optionally, you may connect your
Left/Right speakers as shown below.)
B) Speaker Level Connection
(also knows as "High-Level")
Connect the audio/video receiver's Left/Right main
channel outputs to the Reference Audio L/R Speaker
Level Inputs. Make sure to connect "+" (Red) to "+" (
Red), and "-" ( Black) to "-" (Black). (Optionally, you may
connect your Left/Right speakers as shown below.)
High-Level connection Tip
When using small satellite speakers, connecting the Precision
Acoustics subwoofer with the Speaker Level inputs and then
connecting L/R satellites to the "Speaker out" will automatically limit
the low frequency sent to the small speakers with the high-pass filter
built into the Pecision Acoustics subwoofer. This is helpful to small
speakers, in that they will then not be required to reproduce
frequencies that may be beyond their operating range.
You may now plug your subwoofer's power cord to the
A/C wall outlet. You are now ready to use your new
Precision Acoustics subwoofer.
Do not block the tuned port
Allow a few inches of space behind the subwoofer.
Placement Tip
Bass output varies with position. For more bass output,
place the subwoofer near a wall boundary. Placing the
subwoofer closer to a corner of the room will increase the
bass output considerably.

STEP 3
Powering Up
A) On/Auto/Off
You may choose to have your Subwoofer turn on automatically once it senses an
AUTO
incoming signal. In that case please select the "Auto" position on the back of the
ON OFF
amplifier. The amplifier will turn itself off to stand-by mode if it does not sense a
signal after approximately 10 seconds. When listening at very low levels, the
AUTO
amplifier's signal may be too low to turn the amplifier on automatically. In such
ON OFF
PHASE
cases please select the "On" position on the amplifier.
REV NOR
A) On/Auto/Off
The Phase switch allows your subwoofer to match the output of the bass
PHASE
driver in relation to the other speakers in the listening room. The correct
REV NOR
position for this switch is whichever way produces more perceived bass. You
may experiment by switching between 0º and 180º, and determining which
position sounds best. In most cases, however, leaving the switch in the 0º
position will produce the best results.
C) Setting the Volume and Crossover Frequency
The Crossover Frequency control determines the frequency below which the
FREQ
subwoofer will play. This frequency is manually controlled and is continuously
variable between 50-150Hz. You can experiment with which position works
best with your main speakers by turning this control until the sound of the low
50Hz 150Hz
frequency coming from the subwoofer is nicely blended with the sound of
your main speakers.
Volume
When setting the volume control at the subwoofer, begin with your main
VOLUME FREQ
speakers playing at a normal listening level and the volume control at the
subwoofer completely in the off position (counterclockwise position). Then,
begin to turn up the volume at the subwoofer slowly (clockwise) until the
OFF MAX 50Hz 150Hz
desired bass response is achieved. Bass output will then be regulated by your
A/V receiver's volume control.
Crossover settingTip
When using small speakers (speakers with a 50" or less main woofer) set this control toward the "50" position. When
using larger speakers (speakers with an 8" or more main woofer) set the control closer to the "50" position.
Volume settingTip
Have one person sit at the regular listening position, and a second person turn up the volume at the subwoofer until
the desired bass output is achieved at the listening position. Remember most natural sounding bass results when bass
reproduction is balanced with the main speakers.
