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 80/100Hz
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.
THX Ultra 2 Operation:
On the back panel of the subwoofer select the THX Subwoofer volume level and the
Subsonic, X-Over, and High-Pass Crossover THX settings.

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
X-over, OUT - IN on the rear panel of the subwoofer and set to the OUT 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.
