Always re t u rn to the normal listening location to evaluate any setting c h a n g e s . 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. Please be careful about placing anything directly on top of your subwoofer, as the vibrations of the speaker cabinet could cause these items to shake loose or fall. Connecting the SW 300 The following diagrams show three of the most common types of subwoofer connections. It may be easier to run long distances with speaker wire, although RCA-type connectors will likely produce better sound. Use only the AC adapter provided with this unit. Speaker/Hi Level Inputs and Outputs The inputs are designed to accept an amplified signal from the speaker outputs of a receiver, power amp, television or other device not equipped with line level outputs. The speaker outputs are meant to connect to the inputs of your main left and right speakers. These are only used when the speaker inputs of the SW 300 are used. Line In The RCA-type jacks of your SW 300 are designed to accept a line level signal from a re c e i v e r, pre-amp, surround sound decoder, television or similar device. When using a single line level output from another unit, a Y connector (not included) should be used to send the signal to both the left and right inputs. Please note that only one of these connection options should be used at any one time. Hi Level Connections In this example, the receiver has no subwoofer output. The SW 300 is connected between the front speakers and the receiver via the speaker inputs and outputs. Dedicated Subwoofer Connections Many surround sound decoders, home theater processors and audio/video receivers are equipped with a dedicated subwoofer line output. Connect this line output to the line inputs of the SW 300. A Y connector (not included) may be necessary to feed this single output to both the left and the right line inputs. Television Enhancement Many newer television sets are equipped with variable stereo outputs. The signal available at these outputs varies with the TV volume. In this situation, these variable audio outputs can be connected directly to the SW 300 line inputs to enhance the bass response of the television's built-in speakers.
