Speaker-level Connection
Figures 2 shows an easy way to connect your Velodyne subwoofer
directly to your receiver or integrated amplifier, if it lacks line-level outputs.
You may also connect your satellites directly to your receiver or amplifier
along with the subwoofer. Your receiver or amplifier will not notice the
additional load of the suboofer due to the high input impedance.
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.
Interconnect Cables
When installing your new Velodyne subwoofer using the line level
connections, you should always use shielded phono cables. There are
many decent cables available today, most any of which will work perfectly
well. We do recommend that you keep the length of cable as short as
possible to avoid any potential noise problems.
When using speaker level connections, use a decent quality speaker cable
that mates well with the connectors. Be very careful to avoid any loose
strands or frayed wires which may result in a short, which may damage your
equipment. 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.
Care of Your Subwoofer
Your Velodyne subwoofer does not require any regular maintenance.
Normal dusting or cleaning of the surface for appearance purposes are all
that is required. We suggest you avoid any harsh detergents or chemicals
when cleaning the cabinet. Abrasives, detergents, or cleaning solutions
may damage the finish on the cabinet. We recommend using only a damp
cloth to clean the cabinet.
During normal conditions, your new subwoofer may be left on continuously
without any problems. The unit is equipped with a signal-sensing turn on/
off that will automatically turn on the unit when a signal is present at the
inputs and turn off the unit after several minutes when there is no longer
any signal at the inputs. If you plan to leave the subwoofer unused for an
