CAUTIONS
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicingto qualified service personnel.
The heat sink on the front plate can become hot to the touch. Do not block or cover the heat sink from ventilation. Be sure to keep the microphone away from the front of the speaker after switching the mic sensitivity pad to the OUT position and while setting the microphone level, or very loud feedback will occur! Damage to the system is likely if this occurs!
DO NOT connect the inputs of the PV® 15 PM to the output of a power amplifier. The inputs are meant to be driven from a
DO NOT remove the protective metal grille.
WARNING: The PV® 15 PM 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® 15 PM 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 119 dB at 1 M from the speaker!
Connecting AC Power To The PV® 15PM
The PV® 15 PM comes with an
Connecting a Signal to the PV® 15 PM
There are a variety of ways to input a signal to the PV® 15 PM.
The primary input (5) provides either a balanced mic- or
Do not connect cables to the jacks while the unit is ON and the Volume is turned up!

Use of high quality, premium cables is recommended for the PV® 15 PM, as these usually have better shielding and materials and will provide greater
Volume Control Adjustment
The PV® 15 PM is equipped with a volume control to facilitate use in many different applications. With the volume control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.375 V RMS for
If the mixing board indicates clipping of its output signals, then all of the PV® 15 PM power capability is not being utilized cleanly. Clipping the signal before it gets to the PV® 15 PM is not optimal. Reduce the mixer output level and turn up the volume control on the PV® 15 PM.
The amplifiers in the PV® 15 PM are equipped with DDT™ and an LED indicator to show that DDT™ has engaged. If the sound seems heavily compressed, check this indicator; if it is blinking RED more than occasionally, then the drive level from the mixer (or the volume control on the PV® 15 PM) needs to be reduced.
