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

-

amplifier’s main outputs and

returning them to your amplifier inputs.  When installed in this fashion, your satellite
speakers will be crossed over at 80Hz, which removes the lower bass from your amplifier
and speakers, enabling them 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.

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 filtered and designed to be used with a conventional amplifier 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, below.  

Note: If not using an external crossover, you should use the built

-

in crossover for

optimal performance.
