SC-600D Amplifier User’s Manual
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.

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.

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.
