If the PVXp™ 15 DSP has been subjected to direct sunlight or excessive heat, the built-in thermal protection may
have been triggered. If so, turn off the PVXp™ 15 DSP 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™ 15 DSP is producing a hum or buzz, this can be AC outlet related. Try plugging the PVXp™ 15 DSP
into a different AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and for the PVXp™ 15
DSP, it can cause hum problems. Unless it is not practical, it is best to use the same wall outlet (breaker) to sup-
ply power to both the mixer and the powered speaker.
Ensure that shielded cables have been used to route the signal to the PVXp™ 15 DSP'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™ 15 DSP 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™ 15 DSP, 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 PVXp™ 15
DSP.
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™ 15 DSP 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™ 15 DSP. Ensure that a power amp has not been plugged into the input jack of the PVXp™ 15
DSP. 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 PVXp™ 15 DSP has built-in EQ to smooth and extend the natural response of the speakers. If excessive addi-
tional bass boost or HF boost have been added externally to the PVXp™ 15 DSP, it could cause premature over-
load 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 PVXp™ 15 DSP 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 cover-
age. 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 PVXp™ 15 DSP 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.
