In these installations, you may want to bypass the crossover in either the processor or the Velodyne SC-602 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 connecting the Velodyne SC-602 amplifier to your subwoofer using the speaker level connections, use a high quality speaker cable. 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-602 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 where the greatest output levels and optimum low frequency extension can be found. 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.
