If so, it may have. Turn off the unit, and cool as best as the situation allows. DO NOT use cold liquids for this purpose! Sometimes, if a different circuit breaker is used for the mixer and the Impulse P, it can cause hum problems. Check to make sure light dimmers are not on the same circuit as the Impulse P or the mixer or any source devices. If light dimmers are in use, then it may be necessary to turn them full on or full off to eliminate or reduce hum to tolerable levels.
First, make sure the mixer or signal source is not clipping or being overdriven. This can sometimes occur when the level control 6 on the Impulse P Subwoofer has been set too low too far CCW , 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 P Subwoofer.
Check to see that the proper inputs are being used 5 , and not the high pass filter output 7 , for line level input signals. Make sure that a power amp has not been plugged into the input jacks of the Impulse P Subwoofer.
If an extension cord is being used to provide the AC power to the unit, is it of sufficient current capacity and not also being used to supply power to any other units? The Impulse P Subwoofer has built-in EQ to extend and smooth the natural response of the speaker in the system. Bass boost and infrasonic roll off have been applied, and the system has a nominally flat response, and should require little, if any, additional EQ.
Try backing off of any external mixer, rack Equalizer EQ and see if that clears up any tendency to distort. Finally, realize that even though the Impulse P Subwoofer is an extremely powerful and high output unit, it does ultimately have limits, and it may need additional powered units 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, after checking all the listed things to check, and anything else you can think of to check safely, and the system still exhibits problems, carefully note all conditions and check with your Peavey dealer for advice. Your Impulse P Subwoofer is a sturdy and durable product, which will provide years of reliable use if properly cared for.
Use common sense and read the safety warnings to avoid hazardous operating conditions. 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. Never clean the Impulse P Subwoofer while plugged in or turned on! When the unit has been fully disconnected from AC power sources, a slightly damp cloth can remove soil or other dirt. Never use strong solvents on the Impulse P Subwoofer, as they could attack the polymer that the cabinet is made from.
If the Impulse P Subwoofer cabinet should become scratched or abraded, it can be touched up using a black permanent marker. First, if the area to be touched up is larger than a short scratch, rub it lightly with an soapless plastic scrub pad.
Wipe the scratched or abraded area a little at a time with the black permanent marker, and immediately wipe away the surplus with a lint-free cloth. Notice that the cabinet will be slippery after these treatments.
Rub them down vigorously with a dry lint-free cloth to minimize this. After a long period of use, check the hardware of the Impulse P Subwoofer 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 be less than tight with continued use. The Peavey Impulse P Subwoofer is a powered subwoofer engineered to provide the highest levels of performance in a compact powered loudspeaker.
The enclosure utilizes high-impact polypropylene in an injection-molded plastic trapezoidal form, with a coated perforated metal grille to offer a cosmetically elegant yet durable powered subwoofer. The power amplifier providing the amplification is a low-distortion unit providing W RMS into the nominal 8 ohm load of the woofer. The amplifier was selected for its reliability and superb bass punch.
Internal electronic two-way crossover with active bass boost and subsonic filtering. The powered loudspeaker system shall have a frequency response from 45 Hz to Hz. The peak SPL with inaudible distortion shall reach dB with music as a source, when measured at a distance of 1M and driven to full output capacity.
A volume control will be located next to the input jack group. The input signal shall be electronically divided into high frequencies and low frequencies by a staggered pole third order slope line level crossover at Hz. The low frequencies shall be processed to provide bass boost, subsonic filtering and overall response shaping, and the high frequencies shall be made available via an external output. A handgrip shall be molded in on each side of the woofer and on the top rear edge.
A vinyl coated perforated metal grille shall be provided for woofer protection. The cabinet shall incorporate four tall sturdy rubber feet for floor standing use, and four mounting point inserts on the top and bottom each for flying use. The loudspeaker system shall be called a Peavey Impulse P Subwoofer. Welcome to ManualMachine. We have sent a verification link to to complete your registration.
