INSTALLATION – STEP-BY-STEP
To ensure a quick and awless installation of your Velodyne Digital Drive unit, follow these numbered setup
instructions in their exact order.
SUBWOOFER CABLE CONNECTIONS
Make all necessary cable connections between the applicable subwoofer connector port and your particular
home electronics equipment in the following order:
1. Insert the detachable AC power cord into the 117V~, 60Hz, 15A power interface port on the rear
panel 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 your
receiver/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 input
cable connection. Make a connection between this input and the LFE output or the subwoofer
output of your receiver or processor; OR
b. LFE INPUT (XLR, location 6 on Figure 2) – Make a connection between this input and the
balanced LFE outputs of your receiver or processor; OR
c. INPUT, LEFT and RIGHT (location 11 on Figure 2) – Make a connection between these inputs
and the stereo outputs of your receiver or processor; OR
d. SPEAKER-LEVEL INPUT (location 14 on Figure 2) – Make a connection between these inputs
and the left and right speaker connections on your receiver or processor. Make this connection
by either inserting speaker wire into the correct binding post terminals or by removing the
banana plug jack caps and inserting banana plug wire into the jacks.
NOTE: Refrain from routing connections permanently at this time to accommodate subwoofer
room placement as described below.
3. Establish the line-level connection (optional). Connect to a pre-amplier’s main outputs and
returning them to your amplier inputs. When installed in this fashion, your satellite speakers will be
crossed over at 80Hz, which removes the lower bass from your amplier and speakers, enabling
them to do a better job reproducing high frequencies. By utilizing this method, you will have a bi-
amplied system, gaining improved power and headroom for your system.
A Word About Subwoofer Outputs
The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the digital
built-in crossover. Most processors/receivers have a “subwoofer out” jack that is internally ltered and designed
to be used with a conventional amplier and speaker. 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 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. To
bypass 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.
