RearPanelConnecuons Figure 1 shows the connections on the rear panel of the DLS-R. Following are brief descriptions of the connections described in Figure 1. More detail on these connections can be found on the next page. (1) LOW..PASS CROSSOVER Use this knob to select the high-frequency range at which you wish to cut off the signal to the subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer plays all frequencies up to 200 Hz.
(6) HIGH PASS CROSSOVER Switch This switch selects the frequency for the high pass crossover. This crossover is functional on both line and speaker-level outputs. Smallerspeakerswith limited lowfrequencyoutput may perform better using the higher 100 Hz setting that will reduce the low frequencies sent to them. Larger speakers with greater low frequency output may be able to handle the 80 Hz setting without strain.
You should set the crossover frequency to obtain a smooth and seamless transition from the subwooferto the main speakers in your system. If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency (such as 100-120 Hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 80 Hz.
out" jack that performs this same function and are designed to be used with a powered subwoofer. In these installations, you may want to bypass the crossover in either the processor or the Velodyne subwoofer. In some cases, you may want to use BOTH crossovers. To do this, you can use both your processor's crossover and the one internal to the Velodyne sub. You should stagger the frequencies (i.e., 120 Hz subwoofer, 80 Hz processor) for best results.
room and system conditions often dictate otherwise. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of your listening room. Typically, the optimum location for a subwoofer is in a front corner of your listening room. This location will usually offer the greatest output levels and optimum low frequency extension.
Usage This section addresses day-to-day usage of your DLS-R subwoofer. Remote Control Figure 2 shows the remote control, enabling you to easily choose whatever listening mode you desire. Figure 2.
