SW Ten

Powered Subwoofer with Built-in Active Stereo Crossover

Congratulations on your purchase. We trust that you will enjoy the value and quality of your AudioSource SW Ten for many
years. Please take a few moments to read this manual, and retain it for re f e re n c e .

SW Ten Overview

The AudioSource SW Ten represents the state of the art in powered subwoofers. The highly efficient ported enclosure houses
a rugged ten-inch, reinforced driver, a powerful one hundred-watt amplifier and an integral stereo crossover network. This
precision matched combination ensures the SW Ten will deliver the best sound possible, under even the most demanding
conditions. Both crossover frequency and input level are variable over a wide range, allowing the SW Ten to complement a
wide variety of systems. Line level and hi level inputs and outputs are provided for fast and easy connection to virtually any
system. The three-way auto power and phase reverse functions complete the generous list of features offered by the SW Ten.

A Few Words about Subwoofers

Subwoofers are designed to extend the bass response of your system beyond the limitations of most speakers. This unit is to
be used in conjunction with, not in place of, your existing left and right speakers. The low frequency sounds reproduced by
the subwoofer will radiate equally in all directions. It is not necessary to have a pair of subwoofers. A single subwoofer can
dramatically enhance a stereo TV, a stereo system, or a full fledged home theater.

The advent of digital re c o rding has increased the amount of low frequency information found on re c o rded material. Subwoofers
are designed to accurately reproduce this bass. Similarly, most movies intended for home viewing feature bass well below the
musical range of traditional loudspeakers. However, this information is vital to the impact, ambiance, and believability of a
scene. A subwoofer enhances those elements in your home theater.

Placement Guidelines

Prior to installing your new subwoofer, please consider
the following guidelines. Placing the subwoofer near a wall
or in a corner will greatly increase its bass response. As
f requencies re p roduced by subwoofers are long and need
room to propagate, a subwoofer placed near the listening
position will not sound as full as one placed farther away.

The subwoofer cabinet is designed to blend in with most
decors. If you decide to place anything directly atop your
s u b w o o f e r, please use great caution, as the speaker cabinet
will vibrate and items placed on top may shake loose or fall.

Using the Controls

Power

The power switch has two positions: off, and auto. The
auto position is the default setting. This keeps the amplifier

in a standby mode. Using sophisticated signal sensing
circuitry, the amplifier is activated when a signal is detected
at either of the inputs. If no signal is detected after several
minutes, the amplifier switches back to the standby
mode. The off position overrides this circuit, turning the
subwoofer off manually. The power LED indicates the subwoofer's status.

Phase

The default setting for the phase switch is the 0º position. As the subwoofer is sometimes placed quite a distance from the other speak-
ers, its sound may arrive at your ears milliseconds before or after the sound from your other speakers. In the very rare instances where
the subwoofer is out of phase, the bass will appear somewhat hollow, and the level control may seem to have little or no effect. Setting
the phase switch to the 180º position will compensate for these effects. Note: Phase is relative and can be diff e rent from location to location.

Always return to the normal listening location to evaluate any setting changes.

Level

Since your subwoofer is designed to work in conjunction with other speakers, we have provided a level c o n t rol will allow you to balance
the output of your unit with the rest of your system. Once set, the level control should not re q u i re further adjustment. Begin with the level
c o n t rol at the minimum position. Slowly increase the level until the subwoofer's output is equal to that of your other speakers. Note: Output

level is relative and can be diff e rent from location to location. Always re t u rn to the normal listening location to evaluate any setting changes.

Crossover Frequency

The crossover frequencycontrol is used to adjust the point at which the subwoofer stops reproducing the frequencies played by the
other speakers in your system. Raising the crossover frequency increases the frequencies the SW Ten will reproduce. Lowering the
crossover frequency will do the opposite. Generally, the smaller the speakers used with a subwoofer, the higher the crossover frequency
should be set. We recommend starting at the 12 o'clock position (100 Hz) and moving to the left with larger speakers or to the right
with smaller speakers.

Connecting the SW Ten

General Information

The diagrams on the following page show four of the most common types of subwoofer connections. This information will guide you
through the connection process.

All signals into your unit will first pass through the crossover. The portion of the signal below the current crossover frequency setting
will be reproduced by the subwoofer. The unprocessed signal will also be passed to the hi and line level outputs. If you have a choice
of connection options, remember that it may be easier to run long distances with speaker wire than with line connectors.

Hi Level In

These inputs are designed to accept an amplified signal from the speaker outputs of a receiver, power amp or other device not equipped
with line level outputs.

Hi Level Out

The original amplified signal from your source is present at these outputs, for connection to the existing left and right speakers.

Line In

These RCA jacks are designed to accept a line level signal from a receiver, pre-amp, surround sound decoder or similar device. When
using a single line level output from another unit, a Y connector should be used to send the signal to both the left and right inputs.
(Using the tape loop of a receiver or preamp is not recommended. Tape jacks typically send a constant level, regardless of the volume
setting, unlike preamp outputs. This will affect the balance between the subwoofer and the rest of the system.)

Line Out

The original signal from your source is present at these outputs for connection to another subwoofer or power amplifier.
