CROSSOVERS
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™, 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
DEQ-R subwoofer, or simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum
performance.
