Unpack the system carefully and use the following guidelines in order to find the best room placement option. True subwoofers operate at extremely low frequencies which are primarily omni-directional. [. . . ] Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance. Note: Do not use both the RCA/Phono "INPUT" connections and "SPEAKER LEVEL INPUT" connections simultaneously. Low-Pass Crossover Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 60 to 150 Hz. The subwoofer's response will begin rolling off above the frequency you set this control to. You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to 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. Subwoofer Direct Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 200 Hz into the subwoofer. See below for a more detailed explanation of this feature. Speaker Level Output/Line Level Output When connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes the lower bass from your satellites, enabling them to do a better job reproducing high frequencies and giving your receiver's amp more headroom (up to 50% more power). You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you wish to bypass this crossover. To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections. Be sure that all connections are tight, and that there are no loose strands or frayed wires. Power Switch . The master power switch is located on the lower right half of the unit. This switch should be set to position 1 for on (up), 0 for off (down). www. velodyne. com VDR Series User's Manual 5 A W o r d A b o u t Yo u r R e c e i v e r ' s C r o s s o v e r a n d t h e VDR Crossover Your Velodyne VDR subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover (controlled by the dial on the back panel). Many home theater processors/receivers (Dolby Digital®, DTS®, THX®) have a "subwoofer 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. 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. To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another crossover, simply locate the knob marked "LOW-PASS CROSSOVER" on the rear panel of the subwoofer and turn it counterclockwise to the "DIRECT" position. Note: When not using an external crossover, you should use the built-in crossover for optimal performance. The light will blink according to the following schedule: Figure 2: VDR Remote. 0 degrees 90 degrees 180 degrees 270 degrees 1 2 3 4 blink blinks blinks blinks · LIGHT - If you wish, you can deactivate the blue front panel light on your VDR unit. · NIGHT - Night mode limits the maximum output of the subwoofer for later night listening or to be more considerate of close neighbors. Night mode, when active, is indicated by the reduced intensity of the light.
