Once assured your unit is getting AC power, check that the PVDJ 112P or 115P are 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 Volume controls being used have
been turned up to a satisfactory level (one-third to halfway).
If the PVDJ 112P or 115P have been subjected to direct sunlight or excessive heat, the built-in thermal
protection may have been triggered. The power/clip LED will be illuminated RED if this is the case. If so, turn off
the PVDJ 112P or 115P 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.

If the PVDJ 112P or 115P is producing a hum or buzz, this can be AC outlet related. Try plugging the PVDJ
112P or 115P into a different AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and
the PVDJ 112P or 115P, it can cause hum problems.
Ensure that shielded cables have been used to route the signal to the input of the PVDJ 112P or 115P. If
speaker cables with 1/4" plugs are used as an input cables instead of shielded cables, it will be prone to
hum or buzz.
Hum may be ground loop related. Try lifting the ground connection at the speaker end of the signal cable if
it is a balanced signal cable. Check any input changes carefully by first turning down the volume control,
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 PVDJ 112P or 115P, 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, and not a design
flaw of the PVDJ 112P or 115P. The third wire (ground plug) on the AC plug should NEVER be removed or
broken off.

First, ensure the mixer (signal source) is not clipping or being overdriven. Make sure the volume control/s
(7) and (9) on the PVDJ 112P or 115P have not been set too low.
Check that the input plugs are fully seated in the input jacks (5) and (8) on the rear panel of the PVDJ 112P
or 115P. Ensure that the proper MIC/LINE PAD setting is being used (6) for line-level signals, or that a
power amp has not been plugged into one of the input jacks of the PVDJ 112P or 115P.
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 PVDJ 112P and 115P have built-in EQ to extend and smooth the natural response of the speakers in the
system. Bass boost and HF EQ have been applied and the system has a nominally flat response, so it
should require little, if any, additional EQ. If excessive additional bass boost or HF boost have been added
externally to the PVDJ 112P or 115P, 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 PVDJ 112P and 115P are powerful and high output units, they do
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 PVDJ dealer for advice.
