CONNECTING AC POWER TO THE PR®12D
The PR 12D comes with an
SPECIAL NOTE FOR PERMANENT INSTALLATION
When installing the PR 12D, AC power runs will be used and a certified electrician should be consulted to be sure that all AC wiring complies with local codes and regulations. It is also advisable to use a cable clip properly affixed to the cabinet to strain relief the IEC power cord connected to the amplifier module at (2) so the power cord cannot be pulled out or vibrate loose.

Use of high quality, premium cables is recommended for the PR 12D, as these usually have better shielding and materials and will provide greater
VOLUME CONTROL ADJUSTMENT
The PR 12D 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 PR 12P power capability is not being utilized cleanly. Clipping the signal before it gets to the PR 12D is not optimal. Reduce the mixer output level and turn up the volume control on the PR 12D.
The amplifiers in the PR 12D 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 PR 12D) needs to be reduced.
When first turning on the sound system, switch on all upstream electronics first, then the PR® 12P with its volume control fully counterclockwise (all the way down). Begin checking levels with the mixer output
