Crossovers
Speaker-level Connections
When installed in this fashion the satellite speakers will be crossed
over at 80 Hz. This 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.
Receiver/Processor Subwoofer Outputs
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
"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 VRP subwoofer, or simply setting one crossover
to a higher frequency (such as 120 Hz) will restore maximum
performance.
