Owner’s Manual SW Fifteen Powered Subwoofer with Built-in Active Stereo Crossover Register www.audio s ou rce Onl ine ! ** . net ! Congratulations on your purchase. We trust that you will enjoy the value and quality of your AudioSource SW Fifteen for many years. To ensure the best performance from your unit, please take a few moments to read this manual. Also, be sure to retain this document for future reference. SW FIFTEEN OVERVIEW The AudioSource SW Fifteen represents the state of the art in powered subwoofers. The highly efficient ported enclosure houses a rugged fifteen-inch, reinforced driver, a powerful two hundred-watt amplifier and an integral stereo crossover network. This precision matched combination ensures the SW Fifteen 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 Fifteen 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 Fifteen. 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 recording has increased the amount of low frequency information found on recorded 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. Note: If any part of this product is damaged or missing, do not contact your AudioSource dealer.

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 frequencies reproduced 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. Level 80 Hz 120 Hz 40 Hz 180 Hz Crossover Frequency The subwoofer cabinet is designed to blend in with most decors. If you decide to place anything directly atop your subwoofer, please use great caution, as the speaker cabinet will vibrate and items placed on top may shake loose or fall. L Line In Line Out USING THE CONTROLS 0˚ Off Phase Auto 180˚ Power On Power Hi Level In Left Right Hi Level Out F The power switch has three positions: on, 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 on and off positions override this circuit, turning the subwoofer on or off manually. The power LED indicates the subwoofer's status. R USE T2A 250V RISK OF FIRE REPLACE FUSE AS MARKED 120VAC 180 Watts 60 Hz Phase The default setting for the phase switch is the 0º position. As the subwoofer is sometimes placed quite a distance from the other speakers, 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 different 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 control will allow you to balance the output of your unit with the rest of your system. Once set, the level control should not require further adjustment. Begin with the level control 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 different from location to location. Always return to the normal listening location to evaluate any setting changes. Crossover Frequency The crossover frequency control 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 Fifteen 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 FIFTEEN 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.

The line outputs on the SW Fifteen return the line level signal to the power amp inputs on the stereo receiver, which in turn powers the left and right speakers. Here the signal is already amplified as it leaves the receiver/ amplifier. The speaker terminals of this unit are connected to the hi level inputs of the SW Fifteen. The left and right speakers receive the original amplified signal from the SW Fifteen hi level outputs.

In this case, the signal is already processed and does not need to return to the system or other speakers. Connect this line output to the line inputs of the SW Fifteen. A Y connector should be used to feed this single output to both the left and the right line inputs. Many newer television sets are equipped with variable stereo outputs. The signal available at these outputs varies with the television volume. In this situation, these variable audio outputs can be connected directly to the SW Fifteen line inputs to enhance the bass response of the television's built-in speakers. Enjoy your purchase.
