The Impulse 1015P comes with an 8' IEC connection AC power cord. It is likely that some sort of extension cord
will be used with this powered speaker system, so make sure the extension cord is no longer than necessary and
of a sufficient current capacity to maintain safety. Extension cords no longer than necessary and of the largest
current capacity available will maximize the power output capability of the Impulse 1015P's internal amplifiers.
For best results, do not power anything else from the extension cord used to power the Impulse 1015P. Using a
separate extension cord for this unit will minimize the voltage drop that all extension cords cause. Running just
one extension cord back to the wall plug for the entire sound system is not the way to maximize sound system
performance.
The third wire ground plug on the AC plug should NEVER be removed or broken off, as this seriously
compromises safety.

The built-in pole adapter allows use with the Peavey Q-Wave 118 subwoofer, 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".

The Impulse 1015P has a variety of options for inputting a signal to the system.
Microphone input usage is covered in a specific section below. The balanced line level input/s allow the use of a
1/4" phone plug; either a standard single-ended (tip-sleeve) plug or a balanced TRS (tip-ring-sleeve) type plug;
OR either a male or female XLR plug. Do not connect cables to the jacks while the units are ON and the Volume is
turned up!
While the standard, single-ended 1/4" phone plug will work well and its balanced input circuitry 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. To correct difficult interference problems, it can be
helpful to lift the shield ground on a balanced cable at the Impulse 1015P end only. Check any input changes
carefully, always turning the Volume control down before plugging or unplugging cables.
Use of high quality, premium cables is recommended for the Impulse 1015P, 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 Impulse 1015P's input and to tape down the cables or run them under a cable guard to avoid anyone
tripping over them or pulling the Impulse 1015P over when stand-mounted.

The Impulse 1015P 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 0.5 V RMS for full-rated
output. When driving the Impulse 1015P from a mixer, it may be advantageous to reduce the input sensitivity by
turning the Volume control to the halfway point. The Impulse 1015P will now more closely match a typical power
amp input.
If the mixer board indicates output signal clipping, then the Impulse 1015P's power capability is not being
utilized cleanly. Clipping the signal before it gets to the unit is not optimal. Instead, reduce the mixer output
level and turn up the volume control on the Impulse 1015P.
