of your amplifier or receiver.
3 LINE INPUT jacks
Connect these jacks to the LINE OUT jacks of the amplifier.
4 VOLUME LEVEL knob
Use this knob to adjust the output level of the subwoofer.
5 Power indicator

R e c e i v e r / P r o c e s s o r S u b w o o f e r O u t p u t s
The Velodyne subwoofer is designed to operate using the full range audio signal for input when
using the built-in crossover. Many home theater processors/receivers (Dolby Digital™, DTS™,
THX™) have a “subwoofer out” jack (sometimes labeled “LFE”) that is internally filtered, settable
at the receiver/processor, and designed to be used with a powered subwoofer.
In some
installations, it may be beneficial to use BOTH the Velodyne crossover and the
receiver/processor crossover, resulting in a steeper ultimate crossover slope. 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 crossover
in either the processor or your VX-11 subwoofer. Or, simply set one crossover to a higher
frequency (such as 120 Hz) will restore maximum performance.

Subwoofer Connection Diagram, pages 7 and 8 for connection diagrams.)
