Connecting AC Power to the PR15D

CONNECTING AC POWER TO THE PR®15D

The PR 15D comes with an 8-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 PR 15D. Do not connect any other device to the same extension cord that the PR 15D is connected to.

SPECIAL NOTE FOR PERMANENT INSTALLATION

When installing the PR 15D, 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 PR 15D WITH A SUBWOOFER

The built-in pole adapter allows use with the Peavey SP Subcompact 18X and the accessory pole that it is designed to use, Peavey part #00326540.

The pole used is 36-3/16" long and has a nominal diameter of 1-3/8".

CONNECTING A SIGNAL TO THE PR 15D

There are a variety of ways to input a signal to the PR 15D.

The primary input (5) provides either a balanced mic- or 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. Then there are two line-level unbalanced 1/4" phone jacks that can be mixed in with the primary input.

Do not connect cables to the jacks while the unit is ON and the Volume is turned up!

While a standard single-ended 1/4" phone plug-equipped cable will work well and the balanced input circuitry of the primary input (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 PR 15D end only by using the ground lift switch (4). Check any input changes carefully, always turning the volume control down before plugging and unplugging cables.

Use of high quality, premium cables is recommended for the PR 15D, 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 PR 15D and also to tape the cables down or run them under a cable guard to avoid anyone tripping over them or pulling the PR 15D over when stand mounted.

VOLUME CONTROL ADJUSTMENT

The PR 15D 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 full-rated output. When driving the PR 15D from a mixer, it may be advantageous to reduce the input sensitivity by turning the volume control to the halfway point. The PR 15D will now more closely match a typical power amp.

If the mixing board indicates clipping of its output signals, then all of the PR 15P power capability is not being utilized cleanly. Clipping the signal before it gets to the PR 15D is not optimal. Reduce the mixer output level and turn up the volume control on the PR 15D.

The amplifiers in the PR 15D 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 15D) needs to be reduced.

When first turning on the sound system, switch on all upstream electronics first, then the PR® 15P with its volume control fully counterclockwise (all the way down). Begin checking levels with the mixer output
