TROUBLESHOOTING
No Output at All
First, make sure the unit has AC power and is turned ON. Make sure the LED on the power amp module is
illuminated.
If not, make certain the ON/OFF switch (3) is in the ON position and check the IEC power cord connection (2)
by ensuring it is fully engaged and seated. Make certain the AC line cord is plugged into a working AC outlet.
Finally, check the breaker (1). (See the Rear Panel: Breaker section, for safety instructions.)
Once assured your unit is getting AC power, check that the PVXp 10 is getting a signal. Temporarily disconnect
the cable running to its inputs and connect it to some other device capable of reproducing the signal (i.e., a
power amp and speaker). If this produces a signal, make sure that all Level controls being used have been
turned up to a satisfactory level (one-third to halfway).
If the PVXp 10 has been subjected to direct sunlight or excessive heat, the built-in thermal protection may have
been triggered. If so, turn off the PVXp 10 and let it cool for a sufficient amount of time.
If there is still no output, contact your authorized Peavey
dealer or the Peavey International Service Center.

Hum or Buzz
If the PVXp 10 is producing a hum or buzz, this can be AC outlet related. Try plugging the PVXp 10 into a different
AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and for the PVXp 10, 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 PVXp 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
PVXp 10 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 PVXp 12, 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 PVXp 10.
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
PVXp 10 has not been set too low. Check that the input plug is fully seated in the input jack on the rear panel of
the PVXp 10. Ensure that a power amp has not been plugged into the input jack of the PVXp 10. 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 PVXp 10 has a built-in Contour EQ button to extend and smooth the natural response of the speakers in the
system. When the Contour button is engaged, some Bass boost and HF EQ have been applied and the system
then has a nominally balanced response for background music, so it should require little, if any, additional
EQ. If excessive additional bass boost or HF boost have been added externally to the PVXp 10, 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.
Check to make sure that a line level signal is not being input through the XLR jack, this has 13 dB more gain
than the 1/4" TRS jack, and could be overloading with high mixer output levels.
Finally, realize that even though the PVXp 10 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.
