If the mixing board indicates clipping of its output signals, then all of the PVXp 10 power capability is not
being utilized cleanly. Clipping the signal before it gets to the PVXp 10 is not optimal. Reduce the mixer output
level and turn up the Level control on the PVXp 10. The amplifiers in the PVXp 10 are equipped with DDT
,
™
and the LED indicator will show when DDT has engaged. If the sound seems heavily compressed, check these
indicators; if it is blinking RED more than occasionally, then the drive level from the mixer (or the Level control
on the PVXp 10) needs to be reduced.
When first turning on the sound system, switch on all upstream electronics first, then the PVXp 10 with its Level
control fully counterclockwise (all the way down). Begin checking levels with the mixer output level controls
all the way down, and bring them up slowly with the PVXp 10 Level control set to the desired setting (one-third
recommended to start).
It is not good practice to turn the Level control on the PVXp 10 all the way up and then try to control level only
from the mixer; this approach would tend to pick up excess noise. The best practice would be to run a "hot"
signal from the mixer down the cable to the PVXp 10, and then turn the PVXp 10 Level control up only as much
as necessary to reach the full desired output. With this approach, it is necessary to verify the mixer output is not
clipping.
USING THE PVXP 10 WITH THE PVXP SUB
Recommended settings for use of the PVXp Sub with the PVXp 10 powered speaker.
The ideal location for placement of the powered PVXp 10 speaker is on top of the PVXp Sub pole. In that close
proximity, the following settings will provide the best results in the crossover region, and for tonal balance.
Note that the XLR outputs of the PVXp Sub, have been padded 12 dB to allow the XLR inputs on the PVXp 10 be
used. Normally, these are considered the mic level inputs, but with the PVXp Sub outputs padded, the usage of
the XLR inputs on the PVXp 10 speaker is provided for.
Settings
Phase Switch on PVXp Sub : Normal or IN
PVXp Sub Crossover Frequency Control: From straight up to full CW. This represents a range from approx. 110 Hz
to 160 Hz for the crossover point.
Recommended optimal setting is full CW position.
Level Controls : PVXp Sub Level control at straight up, PVXp 10 Level control at straight up.
CAUTION! SETTING THE CROSSOVER FREQUENCY CONTROL TOO LOW MAY ALLOW THE SATELLITE SPEAKER
TO BE OVERLOADED BY DEEP BASS AT HIGH SPL !
Setting the control lower DOES NOT increase the deep bass output of the PVXp Sub, a middle (straight up) to
higher setting works best for most speakers.
If the PVXp 10 speaker is not set on top of the Subwoofer on the pole, then the polarity switch setting may need
to be different than what is provided here. The Crossover Frequency Control may need to be set to a lower point
in order for the Subwoofer and the PVXp 10 to sum well through the crossover region. The settings outlined
above will work the best when the PVXp 10 speaker and the PVXp Sub are closer together, and essentially the
same distance from the audience.
If there is any question or issue when using the PVXp Sub with the PVXp 10, see the Owner's Manual for the
PVXp Sub for more detailed information.
DISCONNECTING AC POWER TO THE PVXp 10
We recommend that the Power switch (3) 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
disconnected, e.g., as when wiggling the cord.
