the Impulse
®
12D. If an extension cord is being used to provide the AC power to the unit, ensure that it is of
sufficient current capacity and that it is not also being used to supply power to any other device.
The Impulse
®
12D has built-in EQ to extend and smooth the natural response of the speakers in the system.
Bass boost and HF EQ give the system 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
®
12D, it could cause
premature overload at high SPL. Reduce the amount of any external (mixer, rack) EQ and see if that clears up the
distortion.
Finally, realize that even though the Impulse
®
12D is a powerful and high output unit, it does ultimately have
limits, and it may need additional powered units (or a subwoofer) 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.
If the system still exhibits problems after checking everything listed here, carefully note all conditions and check
with your Peavey dealer for advice.
CARE AND MAINTENANCE
Your Impulse
®
12D is a sturdy and durable product and will provide years of reliable use if properly cared for.
Use common sense and read the safety warnings to avoid hazardous operating conditions.
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.
SUNLIGHT/HEAT
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 shutdown.
Do not store in extremely hot or cold conditions or extremely high humidity. Always allow unit to come to room
temperature before use.
CLEANING
Never clean the Impulse
®
12D while plugged in or turned ON! When the unit has been fully disconnected from
AC power sources, use a dry cloth to remove soil or other dirt. Never use strong solvents on the Impulse
®
12D,
as they could damage the cabinet. Do not allow ANY fluids to drip inside the Impulse
®
12D.
TOUCHUP
For an overall finish enhancement and protective coating, use gloves to apply a plastic finish protector, such as
Armor-All
®
protectant or a similar product, to the surface of the plastic cabinet only. Note that the cabinet will be
slippery after these treatments; rub them down vigorously with a dry, lint-free cloth to minimize this.
CHECK FOR SECURE HARDWARE
After the first few months of use and periodically thereafter, check the hardware of the Impulse
®
12D for
tightness, including the rear panel screws and the screws that hold the baffle and rear cabinet together. The unit
is subject to a great deal of vibration, and this could cause them to loosen with use.
