www.velodyne.comDigital Drive Series User’s Manual - 9INSTALLATION – STEP-By-STEPTo ensure a quick and flawless installation of your Velodyne Digital Drive unit, follow these numbered setupinstructions in their exact order.SUBWOOFER CABLE CONNECTIONSmake all necessary cable connections between the applicable subwoofer connector port and your particularhome electronics equipment in the following order:1. Insert the detachable AC power cord into the 117V~, 60Hz, 15A power interface port on the rearpanel of your subwoofer. Plug the male end of the cord into a convenient wall outlet.2. Provide signal to your subwoofer through one or more of the following connections (refer to yourreceiver/processor owner’s manual for available inputs to the subwoofer):a. lFe InPUT (RcA, the Red jack at location 11 on Figure 2) – This is the most common inputcable connection. make a connection between this input and the lFe output or the subwooferoutput of your receiver or processor; ORb. lFe InPUT (XlR, location 6 on Figure 2) – make a connection between this input and thebalanced lFe outputs of your receiver or processor; ORc. INPUT, LEFT and RIGHT (location 11 on Figure 2) – Make a connection between these inputsand the stereo outputs of your receiver or processor; ORd. SPeAKeR-leVel InPUT (location 14 on Figure 2) – make a connection between these inputsand the left and right speaker connections on your receiver or processor. make this connectionby either inserting speaker wire into the correct binding post terminals or by removing thebanana plug jack caps and inserting banana plug wire into the jacks.NOTE: Refrain from routing connections permanently at this time to accommodate subwooferroom placement as described below.3. Establish the line-level connection (optional). Connect to a pre-amplifier’s main outputs andreturning them to your amplifier inputs. When installed in this fashion, your satellite speakers will becrossed over at 80Hz, which removes the lower bass from your amplifier and speakers, enablingthem to do a better job reproducing high frequencies. By utilizing this method, you will have a bi-amplified system, gaining improved power and headroom for your system.A Word About Subwoofer OutputsThe Velodyne subwoofer is designed to operate using the full range audio signal for input when using the digitalbuilt-in crossover. Most processors/receivers have a “subwoofer out” jack that is internally filtered and designedto be used with a conventional amplifier and speaker. In some rare cases, combining both an external crossoverand the one internal to the subwoofer may result in low output and increased noise. In these installations youmay need to bypass the internal crossover in either the processor or Velodyne subwoofer. In some installations,simply setting one crossover to a higher frequency (such as 120Hz) will restore maximum performance. Tobypass the subwoofer’s internal crossover when the unit is being fed a low pass signal from another crossover,refer to the SeTUP instructions at step 14 (page 24).Note: If not using an external crossover, you should use the built-in crossover for optimal performance.
