Use of the PVXp™ 15 DSP with a Speaker Stand
The PVXp™ 15 DSP has a stand mount cup molded-in so that the system can be stand mounted on a standard 1
3/8” (36mm) diameter stand pole.
When using stands or poles, be sure to follow these precautions:
A.
Check the stand or pole specs to make sure that it can support the weight of the PVXp™ 15 DSP (51
lbs./23.2 kg), and observe all safety precautions stated by the stand manufacturer, including the maximum height
the stand is rated for.
B.
Always place the stand on a flat, level and stable surface, and be sure to fully extend the stand legs as per
the stand manufacturer’s instructions.
C.
Try to make sure that the stand legs are oriented for the least danger of tripping to those in the vicinity of
the stand. Never block a doorway or hallway with the legs of a stand.
D.
Try to route cables so that people will not trip over them, or tip the speaker over. Use of duct tape, cable
channels or guards, or other appropriate tie-down/cover –up devices should be carefully considered and imple-
mented.
E.
When installing or de-installing the speaker on the stand, it is a good practice to have a helper if possible,
it can be hard to “thread the needle” and mate the stand cup to the stand pole while holding the PVXp™ 15 DSP
speaker system at arm’s length. It is also helpful if someone holds the speaker stand and pole down while the
PVXp™ 15 DSP is removed from the stand pole, this prevents the PVXp™ 15 DSP from pulling the pole up with it.
F.
When using stands outdoors, never attach banners or flags to the stands or the PVXp™ 15 DSP speaker
system, 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 PVXp™ 15 DSP speaker
system from being blown over.
Connecting a Signal to the PVXp™ 15 DSP
There are a variety of ways to input a signal to the PVXp™ 15 DSP.
The input (4) provides either a balanced mic- or line-level input, allowing the use of a 1/4" TRS (tip-ring-sleeve)
type phone plug or a male XLR plug.
Do not connect cables to the jacks while the unit is ON and the Level knob is turned up! While a standard
single-ended 1/4" phone plug-equipped cable will work well and the balanced input circuitry will provide some
interference rejection, a balanced cable using either the balanced TRS 1/4" phone plug or the XLR plug will pro-
vide superior interference rejection and performance.
Sometimes, with difficult interference problems, it will be helpful to lift the shield ground ( Pin #1 of an XLR) of
a balanced cable at the PVXp™ 15 DSP end. Check any input changes carefully, always turning the Level control
down before plugging and unplugging cables, or lifting the ground.
Use of high quality, premium cables is recommended for the PVXp™ 15 DSP, as these usually have better shield-
ing and materials and will provide greater long-term reliability. The best option is a shielded balanced cable no
longer than necessary to reach the PVXp™ 15 DSP. It is usually a good idea to leave some slack at the input to the
PVXp™ 15 DSP and also to tape the cables down or run them under a cable guard to avoid anyone tripping over
them or pulling the PVXp™ 15 DSP over when stand mounted..
Level Control Adjustment
The PVXp™ 15 DSP is equipped with a Level control (6) on the input to facilitate use in many different applica-
tions. With the Level control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.48 V
RMS for full-rated output with the line level position of the Mic/Line Switch (7). When driving the PVXp™ 15
DSP from a mixer, it may be advantageous to reduce the input sensitivity by turning the Level control to the half-
way point. The PVXp™ 15 DSP™ will now more closely match a typical power amp.
