Read all the installation information below in order to determine which installation option is best for your system. Remember to perform all installation procedures with system power turned off to prevent possible damage. . www. velodyne. com DLS-R User's Manual 1 Placement Subwoofers operate at extremely low frequencies that are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of the listening room. [. . . ] 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. Be sure all connections are tight, and that there are no loose strands or frayed wires. Volume Contr ol This control allows you to balance the output from the subwoofer to the main speakers/amplifier in your system. 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. Cables of extremely large size are typically not required.
