If the
PVX™p 10 Bluetooth® has been subjected to direct sunlight or excessive
heat, the built-in thermal protection may have been triggered. If so, turn off the
PVX™p 10 Bluetooth® and let it cool for a sufficient amount of time.
Try doing a system Restore, as described above in the DSP operating section,
this will return the unit to it's Factory Defaults, and reset all the controls to a
nominal setting, allowing the gain and frequency response to return to "normal".
If there is still no output, contact your authorized Peavey dealer or the Peavey
International Service Center.
Hum or Buzz
If the
PVX™p 10 Bluetooth® is producing a hum or buzz, this can be AC outlet
related. Try plugging the
PVX™p 10 Bluetooth® into a different AC outlet.
Sometimes, if a different circuit (breaker) is used for the mixer and for the
PVX™p 10 Bluetooth®, it can cause hum problems. Unless it is not practical, it
is best to use the same wall outlet (breaker) to supply power to both the mixer
and the powered speaker.
Ensure that shielded cables have been used to route the signal to the
PVX™p
10
’s input. If speaker cables with 1/4" plugs are used as input cables instead of
shielded cables, they will be prone to hum or buzz.
Hum may be ground loop related. It may be helpful to lift the shield ground (Pin
#1) on a balanced cable at the
PVX™p 10 Bluetooth® end. Check any input
changes carefully by first turning down the Level control, before plugging and
unplugging cables, or lifting the shield ground at the speaker end.
Check to make sure light dimmers are not on the same circuit as the
PVX™p 10
Bluetooth®, 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
PVX™p 10 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 PV
X™p 10 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 !
