Troubleshooting
CAUTION! SETTING THE CROSSOVER FREQUENCY CONTROL TOO LOW MAY ALLOW THE SAT-
ELLITE SPEAKER TO BE OVERLOADED BY DEEP BASS AT HIGH SPL !
Setting the control lower DOES NOT increase the deep bass output of the PVs 15 Sub, a middle range (9:30 to
2:30 clock face position) setting works best for most speakers.
If the powered full-range speakers are not set on top of the PVs 15 Sub on the pole, then the polarity switch set-
tings may need to be different than what is provided here. The Crossover Frequency Control may need to be set
to a slightly lower point in order for the Subwoofer and the satellites to sum well through the crossover region.
The settings outlined above will work the best when the satellite speaker and the Subwoofer are closer together,
and essentially the same distance from the audience.
Setting the PVs 15 Sub Controls for Use with Other Satellite Speakers
Crossover Frequency Control (11): In general, for smaller full-range speakers to be used as satellites, set the
Crossover Frequency Control (11) to a higher frequency setting. For larger full-range speakers, set the Crossover
Frequency Control (11) to a lower frequency setting. Setting the Crossover Frequency Control very much below
the 10 o’clock position for smaller satellite speakers will not be needed most of the time, as a crossover frequency
below 110 Hz is not going to allow the PVs 15 Sub and the smaller satellite speaker to add together very well in
the crossover region.
Polarity Switch (12): Try changing the Polarity Switch setting back and forth at each selected crossover frequen-
cy, so as to determine which switch position provides the most bass output in the crossover region. When listen-
ing, either have someone else toggle the Polarity switch, and listen back where the audience will be, or toggle the
polarity and then go listen in the audience area. Listening while standing behind the Sub will not allow you to
hear the correct summation of the Sub and the top speaker.
Level Controls (7): Start with the PVs 15 Sub Level control in the straight up position, and adjust the satellite
speaker system to match it’s level. Note that if the Subwoofer can be heard as a distinctly separate sound source,
then it is probably set too high in level.
Disconnecting AC Power to the PVs 15 Sub
We recommend that the Power switch (4) be used to turn the unit off first, and then the AC power cord can be
removed, this minimizes stress to the power amplifiers and the transducers from turn-off transients. The power
switch has an arc suppression capacitor to help during turn-off, and tends to make a clean disconnect from the
AC power, while the power cord IEC connector can make intermittent contact before finally becoming fully dis-
connected, e.g., as when wiggling the cord.
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 (4) 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 work-
ing AC outlet. Finally, check the fuse (3). (See the Rear Panel: Fuse section, for safety instructions.)
Once assured your unit is getting AC power, check that the PVs 15 Sub is getting a signal. Temporarily discon-
nect 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 Gain/Level controls being used have been
turned up to a satisfactory level (one-third to halfway).
If the PVs 15 Sub has been subjected to direct sunlight or excessive heat, the built-in thermal protection may
have been triggered. If so, turn off the PVs 15 Sub 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.
