Ensure that shielded cables have been used to route the signal to the PV 215D's inputs. If speaker cables
®
with 1/4" plugs are used as input cables instead of shielded cables, they will be prone to hum or buzz.
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 215D 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 215D, the mixer or any source
®
devices. If light dimmers are used, then it may be necessary to turn them full ON or full OFF to eliminate or
reduce hum. This is a typical AC wiring/light dimmer interference problem, not a design flaw of the PV 215D.
®
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 215D 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 215D.
®
Ensure that a power amp output has not been plugged into the input jack (4) of the PV 215D.
®
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 215D has a Contour switch (6) to provide boost of the bass and of the treble for low playback levels.
®
If excessive additional bass boost or high frequency boost have been added externally to the PV 215D 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 (mixer, rack) EQ and see if that clears
up the distortion.
Finally, realize that even though the PV 215D is a powerful and high output unit, it does ultimately have
®
limits, and it may need additional powered units (or a subwoofer) to provide enough sound output or
coverage. 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 and anything else you can think of to check safely, the system still
exhibits problems, carefully note all conditions and check with your Peavey dealer for advice.
Care and Maintenance
Your PV 215D 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 215D 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 215D, as they could damage the cabinet. Do not allow ANY fluids to drip inside the PV 215D.
