Peavey PV 2015 D Manuel D'utilisation page 22

The third wire (ground plug) on the AC plug should NEVER be removed or broken off.
Hum may be ground loop related. It may be helpful to lift the shield ground on a balanced cable at the PV
®
2015D end only, by disconnecting the cable shield at the plug. Check any input changes carefully by first turning
down the level control before plugging and unplugging cables, or changing the grounding.
Check to make sure light dimmers are not on the same circuit as the PV 2015D, the mixer or any source devices.
If light dimmers are used, then it may be necessary to turn them fully ON or fully OFF to eliminate or reduce
hum. This is a typical AC wiring/light dimmer interference problem, not a design flaw of the PV 2015D.
Distorted or Fuzzy Sound
First, ensure the mixer (signal source) is not clipping or being overdriven. Make sure the level control (5) on
the PV 2015D has not been set too low. Check that the input plugs are fully seated in the input jack (4) on the
rear panel of the PV 2015D. Ensure that a power amp output has not been plugged into the input jack (4) of the
PV 2015D. If an extension cord is being used to provide the AC power to the unit, ensure that it is of sufficient
current capacity and that it is not also being used to supply power to any other device.
The PV 2015D has a Contour switch (6) to provide boost of the bass and treble for low playback levels. If
excessive additional bass boost or high-frequency boost have been added externally to the PV 2015D while the
Contour switch is engaged, it could cause premature overload at high SPL. Switch the Contour button OFF, which
is the "out" position, and reduce the amount of any external EQ and see if that clears up the distortion.
Finally, realize that even though the PV 2015D is a powerful and high output unit, it does ultimately have limits,
and you may need additional powered units (or a subwoofer) to provide enough sound output or coverage for
your application. In this case, try turning the mixer levels down a little to see if that clears things up.
If, after checking all the things listed to check and anything else you can think of to check safely, and the system
still exhibits problems, carefully note all conditions and check with your Peavey dealer for advice.
Care and Maintenance
Your PV 2015D is a sturdy and durable product and will provide years of reliable use if properly cared for. Use
common sense and read the safety warnings to avoid hazardous operating conditions.
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.
Sunlight/Heat
Avoid prolonged exposure to direct sunlight, as this may cause the unit to overheat and thermally shut off.
Excessively hot operating conditions can also cause a thermal shutdown.
Do not store in extremely hot or cold conditions or extremely high humidity. Always allow unit to come to room
temperature before use.
Cleaning
Never clean the PV 2015D while plugged in or turned ON! When the unit has been fully disconnected from AC
power sources, use a dry cloth or a plastic bristle brush to remove soil or other dirt. Never use strong solvents
on the PV 2015D, as they could damage the cabinet. Do not allow ANY fluids to drip inside the PV 2015D.
