[. . . ] Typically, the optimum location for a subwoofer is tucked away in a corner of your listening room where the greatest output levels and optimum low frequency extension can be found. The worst location for a subwoofer is far away from any walls and close to the center of your room. Depending on the room size and type of furnishings in the room, perfect placement may not be possible. Finding the best location for your environment will likely require some experimentation. [. . . ] If using line level connections from a preamp or signal processor, use both Left and Right inputs from your preprocessor or preamp and connect them to the Left and Right inputs on your subwoofer. If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to the subwoofer. We recommend setting the subwoofer's level to the 9 o'clock position (the 1/4 volume setting) and then adjust the LFE channel on your receiver or processor to achieve the desired bass output. See your receiver or processor's owner's manual for more information. 2) . www. velodyne. com DLS-R User's Manual 2 Note: A pair of Velodyne subwoofers is a very common setup and doubles your system's bass capability. When using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer by the speaker of the corresponding channel. In this case you may have to use more than one "Y" splitter. The SPEAKER LEVEL jacks connect directly to the speaker outputs of any amplifier, integrated amplifier, or receiver. Your amplifier section will notice no additional loading effects when you use these inputs due to their very high impedance. If using the SPEAKER LEVEL inputs, you DO want to connect both channels, since different bass information might be present in each channel going to your main speakers. Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections - red (positive) to red, and black (negative) to black. Many home theater processors/receivers (Dolby DigitalTM, DTSTM, THXTM) have a "subwoofer out" jack (sometimes labeled "LFE") that is internally filtered, settable at the receiver/processor, and designed to be used with a powered subwoofer. In some installations, it may be beneficial to use BOTH the Velodyne crossover and the receiver/processor crossover, resulting in a steeper ultimate crossover slope. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. In these installations you may need to bypass the crossover in either the processor or your DLS-R subwoofer. Or, simply set one crossover to a higher frequency (such as 120 Hz) will restore maximum performance. (Refer to Figure 2a Line-Level Subwoofer Connection Diagram and Figure 2b Speaker-Level Subwoofer Connection Diagram, pages 7 and 8 for connection diagrams. ) . www. velodyne. com DLS-R User's Manual 5 Interconnect Cables When installing your new Velodyne subwoofer using the line level connections, you should always use shielded phono cables. There are many high quality cables available today, most any of which will work perfectly well. We do recommend that you keep the length of cable as short as possible to avoid any potential noise problems. When using speaker level connections, use a high quality quality speaker cable that mates well with the connectors. Be very careful to avoid any loose strands or frayed wires which may result in a short, which may damage your equipment. Extremely large gauge wire may not properly fit in the binding posts, resulting in a poor connection and possible short circuits.
