A Word About Your Receiver's Crossover and the CHT-R Crossover
your Velodyne CHT-R subwoofer is designed to operate using the full range audio signal for input when using
the built-in crossover (controlled by the dial on the back panel). Many home theater processors/receivers (Dolby
Digital®, DTS®, THX®) have a "subwoofer out" jack that performs this same function and are designed to be
used with a powered subwoofer.
In these installations, you may want to bypass the crossover in either the processor or the Velodyne subwoofer.
In some cases, you may want to use BOTH crossovers. To do this, you can use both your processor's crossover
and the one internal to the Velodyne sub. You should stagger the frequencies (i.e., 120 Hz subwoofer, 80 Hz
processor) for best results.
To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another
crossover, simply locate the knob marked "LOW-PASS CROSSOVER" on the rear panel of the subwoofer and
turn it counterclockwise to the "DIReCT" 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. When using a single RCA sub out from the processor, it does not matter
which line level input (L/R) is used.
