mance you should bypass the internal crossover in your Velodyne
subwoofer, the Subwoofer Direct feature.
To bypass the crossover within the subwoofer, simply locate the
switch marked "out / in" on the back panel of the subwoofer and set
to the "out" position. This will eliminate the internal crossover
function.
Note
If not using an external crossover, you should use the built-in
crossover for optimal performance.

Processor
From the low pass output of your signal processor Install into right
or left RCA line in connector in the back of the subwoofer or use a
"Y" connector adapter into both right and left RCA line in connectors
in the back of the subwoofer, and switch the crossover switch to
"out".
Speaker-level connection
Figure 2 shows an easy way to connect your VA-907.2 subwoofer
directly to your receiver or integrated amplifier.
When connected in this fashion, your satellite speakers will be
crossed over at 85 Hz, which removes the lower bass from your
speakers thus, enabling them to do a better job reproducing high
frequencies.
You may also connect your satellites directly to your receiver or
amplifier along with the subwoofer if you wish to bypass the internal
high-pass crossover.
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.

Line-level connection
Figure 1 shows connection 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 85Hz which removes the lower bass from your
amplifier and speakers, enabling them to do a better job reproduc-
ing 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 outputs
The Velodyne subwoofer is designed to operate using the full range
audio signal for input when using the built-in crossover. Some
surround sound processors/receivers, including the Dolby AC3
system with their .1 channel output, have a "subwoofer out" jack that

is already crossed over and designed to be used with a conventional
amplifier and speaker. Combining both an external crossover and
the one internal to the subwoofer may result in low output and
increased noise. In these cases, to optimize your subwoofer perfor-
