User manual VELODYNE DLS-5000R DATASHEET

[. . . ] Retain Instructions -- The safety and operating instructions should be retained for future reference. Heed Warnings -- All warnings on the subwoofer and in the operating instructions should be adhered to. Follow Instructions -- All operating and use instructions should be followed. Water and Moisture -- The subwoofer should not be used near water -- for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool or the like. [. . . ] Note: Volume is also controllable by using the supplied remote, when defaults are restored. (3) AUTO ON/OFF Switch Use this switch to select between auto-on (active) and constant on (inactive) operation. DLS-5000R Rear Panel Connections (4) LINE OUTPUT Connect these jacks to the LINE IN preamp input to use the DLS-R's internal high pass crossover. See below for a more detailed explanation of this crossover. 4 5 (5) LINE INPUT/LFE Input Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks of your receiver/processor. If using the LFE output from your receiver or processor, plug the single cable into the "L" ­ LFE input or, for more signal, use a "Y" connector and feed the signal into both "R" and "L" inputs. (6) HIGH PASS CROSSOVER Switch This switch selects the frequency for the high pass crossover. Smaller speakers with limited low frequency output 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. (7) SPEAKER LEVEL INPUT Terminals Connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, when you go to the receiver speaker set up menu, make sure you select the large speaker option (8) SPEAKER LEVEL OUTPUT Terminals Sends a crossed-over speaker-level signal to the front speakers. See below for a more detailed explanation of this crossover. 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. 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: If not using an external crossover, you should use the built-in crossover for optimal performance. When using a single RCA sub out from the processor, it does not matter which line level input (L/R) is used. Caution! This subwoofer has electronics built into the cabinet. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc. Do not place the unit near sources of excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not be walked on, pinched, or compressed in any way that could result in damaging the insulation or wire. Interconnect Cables When installing your new Velodyne subwoofer using the line-level connections, you should always use shielded phono cables. There are many decent 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. [. . . ] During normal conditions, the subwoofer may be left on continuously without any problems. If you plan to leave the unit unused for an extended period of time, we recommend that you turn off the unit by the master power switch on the rear panel. 1000 watts Dynamic/ 52. 5 x 46 x 52 15" forward firing 21" x 18. 4" x 20. 75" DLS-5000R 28Hz-120Hz (+/-3 dB) 25Hz-120Hz (+/- 3 dB) 160 watts RMS power 175 watts RMS power 200 watts RMS power 400 watts Dynamic/ 45 x 37. 5 x 47. 5 12" forward firing 80Hz or 100 Hz (6 dB/octave slope) Line-level and speaker-level Line-level and speaker-level 1.
