P
Power Switch
The master power switch is located on the lower half of the unit. This
rocker style switch is the main on/off for the unit. This switch should be
set to position 1 (up) for on, and 0 (down) for off. If the unit is to be left
unused for an extended period of time, the master power switch should
be turned off.
Subwoofer Outputs
The Velodyne subwoofer is designed to operate using the full range
audio signal for input when using the built-in crossover. Some
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
120 Hz) will restore maximum performance. To bypass the subwoofer’s
internal crossover when the unit is being fed a low pass signal from
another crossover, simply locate the switch marked
INTERNAL
X-OVER/SUBWOOFER DIRECT
on the rear panel of the subwoofer
and set to the
SUBWOOFER DIRECT
position. This will eliminate the
internal crossover from the signal path.
NOTE: If not using an external crossover, you should use the built-
in crossover for optimal performance.
LINE-LEVEL CONNECTION - OPTION A
Figure 1 shows connection from your home theater receiver to the LFE
input on the back of your subwoofer. When the subwoofer is installed in
this fashion, all of the low frequency information from your “LFE Out” or
“Subwoofer Out” on the back of your receiver will pass into your
Velodyne subwoofer. This connection is the most common connection
method when using your subwoofer with a 5.1 receiver. (Cable needed:
1 mono RCA cable.)
