Caution!!! To avoid damage to your main amplier, 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 quality cables available. We 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 quality speaker wire 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 in turn, damage your
equipment. Extremely large gauge wire may not properly t 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 nish 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/o that will automatically turn on the unit when a signal is present at the
inputs and turn o 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 extended period of time, we recommend that you turn o the master power
switch on the rear panel.
PROTECTION CIRCUITRY
Your new subwoofer is equipped with special protection circuitry to provide maximum performance with greatest
reliability.
The unit is protected against:
1) Overdriving the speaker or amplier
2) Overheating the amplier
3) Excessive drop in power line voltage
The rst type of protection circuitry which prevents overdriving of the speaker or amplier operates constantly
without being audible under most situations. In some extreme situations (sustained high output levels such as
pro sound usage), the unit may shut down momentarily. This indicates the thermal or under-voltage protection
circuitry has engaged. If this should happen, you should reduce the volume setting or shut the unit o until
normal operating conditions return. You may also want to plug the unit into a dierent wall outlet, as dropping
power line voltage will be most noticeable under strenuous conditions and may result in the unit shutting down
intermittently.
