CAUTIONS
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.
NOTE: This unit is not designed for overhead suspension!
The heat sink on the back plate can become hot to the touch. Do not block or cover the heat sink from
ventilation.
DO NOT connect the inputs of the PV
from a line-level strength signal.
When connecting a microphone to the system, be sure to keep the microphone away from the front of the
speaker while setting the microphone level, or very loud feedback will occur! Damage to the system is likely if
this occurs!
DO NOT remove the protective metal grille.
WARNING: The PV
115D is very efficient and powerful! This sound system can permanently damage hearing!
®
Use extreme care setting the overall maximum loudness!
The apparent sound level of the PV
distortion or obvious distress can make the sound level seem much lower than it actually is. This system is
capable of SPL in excess of 121 dB at 1 meter from the speaker!
Connecting AC Power To The PV
The PV
115D comes with a 6-foot IEC connection AC power cord. If you are using an extension cord or power
®
strip with this powered speaker, make sure it is of good quality and of a sufficient current capacity to maintain
safety and maximize the power output capability of the PV
extension cord that the PV
Connecting a Signal to the PV
There are a variety of ways to input a signal to the PV
input, allowing the use of a 1/4" phone plug, either a standard single-ended (tip-sleeve) plug or a balanced TRS
(ring-tip-sleeve) type plug OR a male XLR plug.
Do not connect cables to the jacks while the unit is ON and the Level is turned up!
While a standard shielded single-ended 1/4" phone plug-equipped cable will work well and the balanced input
circuitry of the input jack (5) will provide some interference rejection, a balanced cable using either the balanced
TRS 1/4" phone plug or the XLR plug will provide superior interference rejection and performance. Sometimes,
with difficult interference problems, it will be helpful to lift the shield ground on a balanced cable at the
PV
115D end. Check any input changes carefully, always turning the volume control down before plugging and
®
unplugging cables or making grounding changes.
Use of high quality, premium cables is recommended for the PV
and materials and will provide greater long-term reliability. It is usually a good idea to leave some slack at the
input to the PV
115D and also to tape the cables down or run them under a cable guard to avoid anyone tripping
®
over them or pulling the PV
Level Control Adjustment
The PV
115D is equipped with a level control (6) to facilitate use in many different applications. With the level
®
control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.650 V RMS for full-rated
output. When driving the PV
turning the level control to the halfway point or even less. The PV

If the mixing board indicates clipping of its output signals, then all of the PV
utilized cleanly. Clipping the signal before it gets to the PV
