During installation of your Velodyne Acoustics MicroVee X subwoofer using the line level connections, you should always
use shielded RCA 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 careful to
avoid any loose strands or frayed wires that may result in a short, which could damage your equipment. Be aware that cables
of extremely large size are not required due to the low current draw of this type of connection. Please note that extremely
large gauge wire may not properly fit in the terminals, resulting in a poor connection and possible short circuits.
In regards to care of your Velodyne Acoustics subwoofer, 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. The finish on the
cabinet may become damaged with the use of abrasives, detergents, or cleaning solutions. We highly recommend using only
a damp cloth to clean the cabinet.
Under normal conditions, your subwoofer may be left on continuously without any problems. The unit is equipped with a
signal-sensing on/off circuit 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 Velodyne Acoustics subwoofer is equipped with circuitry to provide maximum performance with greatest reliability.
The unit is protected against:
1) Overheating the amplifier.
2) Excessive drop in power line voltage.
If either of the above should happen, you should reduce the volume setting or shut the unit off until normal operating con-
ditions 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.
Please re-check all systems and verify your connections and settings before contacting an authorized service center.
Following is a simple troubleshooting guide to assist you.
1. Verify that the unit is plugged in and power outlet used is active.
2. Is the power switch on?
3. Is the unit receiving an input signal from your source?
4. Have all controls (volume, crossover, phase, etc.) been properly set?
5. If the unit has been running at high levels, one of the protection circuits may be engaged.
Has the amplifier overheated?
6. Make sure the speaker wires are fully inserted into the spring clip connectors and that no wires are touching from
one terminal to another.
If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal. Under more
serious conditions, the unit may shut off completely. Upon cooling, normal operation should return. However, you may be
required to turn the power off and then on again to reset the unit before it will operate normally again.
The following conditions require service by a qualified technician:
1. The power cord has become damaged or appears damaged.
2. The unit does not appear to operate normally or exhibits a marked change in performance.
3. The unit has been exposed to water.
4. Some part of the cabinet or circuitry is physically damaged.
