Velodyne SPL-1000R User Manual - And The Spl-R Crossover

seamless transition from the subwoofer to the main speakers in

your system.  If your main speakers are smaller units with limited

low frequency output, you may wish to choose a higher frequency

(such as 100-120 Hz) than you would with larger speakers which

have greater low frequency output.  With larger speakers, you

might start with this control set lower, such as 80 Hz. 

Subwoofer Direct

Subwoofer Direct is the leftmost setting on the low-pass

crossover knob and will allow frequencies up to 200 Hz into the

subwoofer.  If you are not using an external crossover, we

recommend that you use the one provided within the unit for

optimum performance.  

Caution!!!

To avoid damage to your main amplifier, be sure to maintain

correct polarity when making all connections.  Red (positive) to

red, and black (negative) to black.  Be sure that all connections

are tight, and that there are no loose strands or frayed wires. 

Power Switch

The master power switch is located on the lower right half of the

unit.  This rocker style switch is the main on/off for the unit. This

switch should be set to position 1 for on (up), 0 for off (down).

A Word About Your Receiver’s Crossover 

and the SPL-R Crossover

Your Velodyne SPL-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.
