VMS User’s Manual

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 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 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. 

Before seeking service for your amplifier or subwoofer, please re-check all systems. 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 binding posts are tightened.

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. Normal
operation should return upon cooling, but you may be required to turn the power off and then
on again to reset the unit.

The following conditions require service by a qualified technician: 

1.  The power cord has become 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 chassis or circuitry is physically damaged
