Introduction
Congratulations on your purchase! Your new Acoustic Audio
powered subwoofer was designed and manufactured to deliver
refined musical reproduction and vivid home theater entertainment.
Acoustic Audio products are constructed using the finest quality
components and we are proud of our custom designed drivers and
electronics. Much effort has gone into the design of your new sub as
to help you achieve years of maximum performance and listening
pleasure. Every Acoustic Audio loudspeaker undergoes rigorous
testing and quality controls at the factory to ensure years of
listening pleasure. Please take a moment to read this manual prior
to installing your new subwoofer. The information provided will
help you obtain maximum performance.
Though this manual will refer to your receiver, the instructions and
recommendations apply to all consumer amplifiers as well as AV
receivers. Acoustic Audio powered subwoofers are designed for
indoor use only.
IMPORTANT: It is important to turn off the power to your receivers
power supply before connecting the subwoofer to your system.
Placement
Your Acoustic Audio subwoofer can be placed in many convenient
locations in your home, but must be placed on the floor. Do not
attempt an installation that would elevate the subwoofer above
floor level. You should experiment with various placements. Small
changes in the placement location and adjustments to subwoofer
controls can produce large apparent differences for room acoustics.
For example, directing the woofer of a forward firing sub toward
one's typical listening position and adjusting the low pass filter to
140 Hz can make the sub very directional. This means you perceive
exactly where the sub is located within the room. This is not a
desirable result for the most realistic audio experience.
The common thinking regarding subwoofer placement and
performance is to position and adjust the subwoofer in such a way
that the subwoofers low frequencies encompasses the entire room
with deep powerful bass and provides the most realistic theater
experience. The amount of bass perceived increases as you move
the subwoofer closer to an intersecting wall surface and the highest
level of bass results are realized from placement in a corner, but
should be no closer than 3" from the wall surface. The floor and
corner placement are actually an important part of the subwoofer's
design. Attempt to place the subwoofer in or near the corner closest
to your system's receiver to ensure the shortest possible wire or
cable runs, which will result in superior performance.

Connecting Speakers
Connecting & Adjusting Your Subwoofer
When you make connections, make sure that the power switches of
all components, including subwoofer, are OFF.
Power Cord
The attached power cord is to be used with a standard AC wall
outlet (110 Volt AC outlet capable of supplying at least 250 Watts)
Power Indicator LED
The LED light glows RED when the subwoofer is OFF or in standby
mode. When the subwoofer is ON or receiving an audio signal in
Auto On mode the LED will glow green.
Power Switch
The subwoofer has an Auto On feature for your convenience. When
the subwoofer is set in the Auto On mode it is not necessary to
power your subwoofer completely off when not in use. In Auto On,
the subwoofer stands by until it detects an audio signal input, then
the subwoofer turns on automatically. A few minutes after audio
input signals cease, the subwoofer automatically returns to stand by
mode. The subwoofer has been designed in such a way that you can
leave the Auto On feature active without causing any harm to your
subwoofer.
Fuse
The fuse protects against minor internal and external faults. The
fuse value is indicated on the rear amplifier plate near the fuse itself.
If the Power switch is ON and the Power Indicator LED is unlit,
unplug the power cord from the AC outlet and check the fuse by
unscrewing the center piece from the holder. IMPORTANT: If the fuse
malfunctions, replace it with another fuse of the same type, value
and current rating. This information can be found on the fuse.
Line- In Jacks
Option 1: This jack is for input connection using an audio cable (low
level) See options 1 & 2 descriptions on the following page
Speaker - In Terminals
Option 2:These terminals are for making connections using speaker
wire (high level)
Low Pass Frequency (LPF) Crossover
This feature adjusts the frequency limit for low audio signals. This
control helps you adjust the system's low frequency balance to
blend your subwoofer with the other speakers within your system.
An example: if you adjust the control to the subwoofer's low setting,
the filter limits frequencies above that from being reproduced or
heard from the subwoofer. This can be a desired setting if you are
using the sub in combination with tower or floor-standing speakers.
If you are using satelite speakers with 5.25" cone sizes or under, you
will want to move the frequency up to slightly overlap the lowest
frequency the satellites can produce. For example, if your satellite
frequency response is rated at 80Hz to 18 kHz then you may choose
