Illuminates GREEN when the electronics receive power (when the Power switch (3) is ON). Illuminates RED
when amplifier clipping is occurring.
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 1015D to the output of a power amplifier. The inputs are meant to be
driven 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 1015D 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 1015D can be deceiving due to its clear, clean sound output. The lack of
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 1015D
The PV 1015D 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 1015D. Do not connect any other device to the same
extension cord that the PV 1015D is connected to.
Connecting a Signal to the PV 1015D
There are a variety of ways to input a signal to the PV 1015D.
The input jack (5) provides a balanced line-level 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 1015D 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 1015D, as these usually have better shielding
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 1015D and also to tape down the cables or run them under a cable guard to avoid anyone
tripping over them or pulling the PV 1015D over when stand mounted.
Level Control Adjustment
The PV 1015D 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 1015D from a mixer, it may be advantageous to reduce the input sensitivity by
turning the level control to the one-third point or even less. The PV 1015D will now more closely match the
sensitivity of a typical power amp.
If the mixing board indicates clipping of its output signals, then all of the PV 1015D power capability is not being
utilized cleanly. Clipping the signal before it gets to the PV 1015D is not optimal. Reduce the mixer output level
and turn up the level control on the PV 1015D.
