hen installing your new Velodyne subwoofer using the line level connections, you should
always use shielded phono cables. There are many high quality cables available today. It is
recommended that you keep the length of cable as short as possible to avoid any potential
noise problems.
When using speaker level connections, use a high quality speaker cable that mates well with
the connectors. Be very careful to avoid any loose strands or frayed wires that may result in a
short, which may damage your equipment. Cables of extremely large size are not required due
to the low current draw of this type of connection. Extremely large gauge wire may not properly
fit in the terminals, resulting in a poor connection and possible short circuits.
Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning
of the surface for appearance purposes is 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.
Your new subwoofer is equipped with circuitr
y to pr
ovide maximum per
for
mance with
gr
eatest reliability.
The unit is protected against:
1) Overheating the amplifier.
2) Excessive dr
op in power line voltage.
If either of the above should happen, you should r
educe the volume setting or shut the unit of
f
until nor
mal operating conditions return. You may also want to plug the unit into a different wall
outlet, as dropping power line voltage will be most noticeable under strenuous conditions and
may result in the unit shutting down intermittently.
