Peavey PV 1015 D Manuel D'utilisation page 23

E. When installing or un-installing the speaker on the stand, it is a good practice to have a helper if possible.
It requires concentration to "thread the needle" and mate the stand cup to the stand pole while holding the
®
PV 1015D speaker system at arm's length. It is also helpful if someone holds the speaker stand and pole down
while the PV 1015D is removed from the stand pole, this prevents the PV 1015D from pulling the pole up with it.
®
F. When using stands outdoors, never attach banners or flags to the stands or the PV 1015D speaker system,
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 1015D speaker system from
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 1015D 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 Volume controls being used have been
turned up to a satisfactory level (one-third to halfway).
If the PV 1015D 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 1015D 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 PV 1015D is producing a hum or buzz, this can be AC outlet related. Try plugging the PV 1015D into a
®
different AC outlet. Sometimes, if a different AC power circuit (breaker) is used for the mixer and the PV 1015D,
it can cause hum problems.
Ensure that shielded cables have been used to route the signal to the PV 1015D enclosure's inputs. If speaker
cables with 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 1015D
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 1015D, the mixer or any source devices.
If light dimmers are used, then it may be necessary to turn them full, 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 PV 1015D.
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 1015D 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 1015D. Ensure that a power amp output has not been plugged into the input jack (5) of
the PV 1015D. 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 1015D has a Contour switch (7) to provide boost of the bass and treble for low playback levels. If
®
excessive additional bass boost or high-frequency boost have been added externally to the PV 1015D while 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 EQ and see if that clears up the distortion.
Finally, realize that even though the PV 1015D is a powerful and high output unit, it does ultimately have limits,
and you may need additional powered units (or a subwoofer) to provide enough sound output or coverage for
your application. 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.
