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 PVX™p 12 Bluetooth®.
The third wire (ground plug) on the AC plug should NEVER be removed or
broken off, as this is a potential safety hazard.
Distorted or Fuzzy Sound
First, ensure the mixer (signal source) is not clipping or being overdriven. Make
sure the Level (6) control on the PVX™p 12 Bluetooth® has not been set too
low.
Make sure that the MIC/LINE Switch (6), is not in the mic position when driving
the system with a line level signal. The analog input circuitry and the DSP
system will overload and cause severe distortion that can not be removed by
turning down the Level control !
Check that the input plug is fully seated in the input jack on the rear panel of the
PVX™p 12 Bluetooth®.
Ensure that a power amp has not been plugged into the input jack of the PVX™p
12 Bluetooth®.
If an extension cord is being used to provide the AC power to the unit, insure that
it is of sufficient current capacity and that it is not also being used to supply
power to any other device.
The PVX™p 12 Bluetooth® has built-in EQ to extend and smooth the natural
response of the speakers in the system. If excessive additional bass boost or
HF boost have been added externally to the PVX™p 12 Bluetooth®, it could
cause premature overload at high SPL. Reduce the amount of any external
(mixer, rack) EQ and see if that clears up the distortion.
Finally, realize that even though the PVX™p 12 Bluetooth® 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 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 PVX™p 12 Bluetooth® 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.
