First, make sure the mixer (or signal source) is not clipping or being overdriven. This can sometimes occur when
the Volume control (6) on the Impulse 1015P has been set too low (too far counterclockwise), and it takes a lot of
signal to drive the unit to full power.
Make sure the input plugs are fully seated in the input jacks (5) on the rear panel of the Impulse 1015P.
Check to see that the proper inputs are being used (5) for line-level signals, not the mic input (8). Make sure that
a power amp has not been plugged into the input jacks of the Impulse 1015P.
If an extension cord is being used to provide AC power to the unit, is it of sufficient current capacity and not also
being used to supply power to any other units? See “GETTING AC POWER TO THE IMPULSE 1015P” for details.
The Impulse 1015P has built-in EQ to extend and smooth the natural response of the speakers in the system.
Bass boost and HF EQ have been applied, and the system has a nominally flat response, so it should require
little, if any, additional EQ. If excessive additional bass boost or HF boost have been added externally to the
Impulse 1015P, it may cause premature overload at high SPLs. Try backing off of any external EQ (mixer, rack
equalizer) and see if that clears up any tendency to distort. If the Contour switch (9) has been engaged, defeat it
by making sure it is in the OFF position.
Even though the Impulse 1015P is an extremely powerful and high output unit, it does ultimately have limits, and
it may require additional powered units (or a sub-woofer) to provide enough sound output or coverage. In this
case, try turning the mixer levels down a little to see if that clears things up.
After checking everything listed to check in this manual and anything else you can think of to check safely, if the
system still exhibits problems, carefully note all conditions and check with your Peavey dealer for advice.

Your Impulse 1015P is a sturdy, durable product that will provide years of reliable use if cared for properly. Use
common sense and read the safety warnings to avoid hazardous operating conditions. Tightening the bolts on
the rear panel may require that the front speaker grille be removed, and then the woofer, and reaching in from
the front to restrain the nuts from spinning.
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.

Avoid prolonged exposure to direct sunlight, as this may cause the unit to overheat and thermally shut off.
Excessively hot operating conditions can also cause a thermal shut down.
Do not store in extremely hot or cold conditions or extremely high humidity. Always allow unit to come to room
temperature before use.
