In these installations, you may want to bypass the crossover in either the processor or the velodyne SC-600D
amplifier as described above. However, in some cases you may want to use BOTH crossovers. If you choose to
do this you should stagger the frequencies, (i.e., 120 Hz subwoofer, 80 Hz processor) for best results.
Note: If not using an external crossover, you should use the subwoofer’s 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.
A WORD ABOUT INTERCONNECT CABLES
When installing your Velodyne SC-600D amplifier using the line-level connections, you should always use high
quality shielded interconnect cables. It is recommended that you keep the length of cable as short as possible
to avoid any potential external interference problems.
When connecting the SC-600D amplifier to your subwoofer, use a quality speaker cable that is at least 14-gauge.
Be very careful to avoid any loose or frayed strands that could result in a short, causing a dangerous condition
and possible damage to your unit. Cables of extremely large size are typically not required. Extremely large
gauge wire may not properly fit in the binding posts, resulting in a poor connection and possible short circuits.
A WORD ABOUT SUBWOOFER PLACEMENT
Subwoofers operate at extremely low frequencies, which are primarily omni-directional. Keep in mind that
frequency response and output level can be drastically influenced by room placement, depending on the
acoustic properties of the listening room. Typically, the optimum location for a subwoofer is in a front corner
of your listening room. This location will usually offer the greatest output levels and optimum low frequency
extension. Typically, a minimum distance of one to two feet from your Tv to the subwoofer will be adequate to
avoid any magnetic interference.
Remember that the built-in 5-band EQ will help to get the most performance out of your subwoofer no matter
where it is placed.
Caution!
This amplifier is an electronic device. Do not place the amplifier next to sources of heat such as furnace
registers, radiators, etc. Likewise, do not place the amplifier near sources of excessive moisture, such
as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not
be walked on, pinched or compressed in any way that could result in damaging the insulation or wire.
