Troubleshooting - Peavey PV 115 D Operating Manual

E. When installing or de-installing the speaker on the stand, it is a good practice to have a helper if possible,
as it can be hard to "thread the needle" and mate the stand cup to the stand pole while holding the PV
speaker system at arm's length. It is also helpful if someone holds the speaker stand and pole down while the
PV 115D is removed from the stand pole- this prevents the PV
®
F. When using stands outdoors, never attach banners or flags to the stands or the PV
as strong winds may cause the speaker to blow over. If there is a possibility of windy conditions, then it may
be prudent to consider weighting or locking down the stand legs to prevent the PV
being blown over.

TROUBLESHOOTING

No Output at All
First, make sure the unit has AC power and is turned ON. Make sure the Power/Clip LED (9) is illuminated Green.
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 fuse (2a). (See the Rear Panel: Fuse section for safety instructions.)
Once assured your unit is getting AC power, check that the PV
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 PV 115D has 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 PV
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 PV 115D is producing a hum or buzz, this can be AC outlet related. Try plugging the PV
®
different AC outlet. Sometimes, if a different AC power circuit (breaker) is used for the mixer and the PV
can cause hum problems.
Ensure that shielded cables have been used to route the signal to the PV
1/4" plugs are used as input cables instead of shielded cables, they will be prone to hum or buzz.
The third wire (ground plug) on the AC plug should NEVER be removed or broken off.
Hum may be ground loop related. It may be helpful to lift the shield ground on a balanced cable at the PV
end only by disconnecting the cable shield at the plug. Check any input changes carefully by first turning down
the level control before plugging and unplugging cables or changing the grounding.
Check to make sure light dimmers are not on the same circuit as the PV
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 PV
Distorted or Fuzzy Sound
First, ensure the mixer (signal source) is not clipping or being overdriven. Make sure the level control (6) on the
PV 115D has not been set too low.
®
Check that the input plugs are fully seated in the input jack (5) on the rear panel of the PV
Ensure that a power amp output has not been plugged into the input jack (5) of the PV
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 PV 115D has a Contour switch (7) to provide boost of the bass and of the treble for low playback levels.
®
If excessive additional bass boost or high frequency boost have been added externally to the PV
the Contour switch is engaged, it could cause premature overload at high SPL. Switch the Contour button OFF,
which is the out position, and reduce the amount of any external (mixer, rack) EQ and see if that clears up the
distortion.
