seamless transition from the subwoofer to the main speakers in
your system. If your main speakers are smaller units with limited
low frequency output, you may wish to choose a higher frequency
(such as 100-120 Hz) than you would with larger speakers which
have greater low frequency output. With larger speakers, you
might start with this control set lower, such as 80 Hz.
Subwoofer Direct
Subwoofer Direct is the leftmost setting on the low-pass
crossover knob and will allow frequencies up to 200 Hz into the
subwoofer. If you are not using an external crossover, we
recommend that you use the one provided within the unit for
optimum performance.
Caution!!!
To avoid damage to your main amplifier, be sure to maintain
correct polarity when making all connections. Red (positive) to
red, and black (negative) to black. Be sure that all connections
are tight, and that there are no loose strands or frayed wires.
Power Switch
The master power switch is located on the lower right half of the
unit. This rocker style switch is the main on/off for the unit. This
switch should be set to position 1 for on (up), 0 for off (down).
A Word About Your Receiver’s Crossover
and the SPL-R Crossover
Your Velodyne SPL-R subwoofer is designed to operate using
the full range audio signal for input when using the built-in
crossover (controlled by the dial on the back panel). Many home
theater processors/receivers (Dolby Digital®, DTS®, THX™)
have a “subwoofer out” jack that performs this same function and
are designed to be used with a powered subwoofer.
In these installations, you may want to bypass the crossover in
either the processor or the Velodyne subwoofer. In some cases,
you may want to use BOTH crossovers. To do this, you can use
both your processor
’
s crossover and the one internal to the
V
elodyne sub.
You should stagger the frequencies, (i.e., 120 Hz
subwoofer
, 80 Hz processor) for best result
