User manual PEAVEY IMPACT 1

[. . . ] Refer servicing to qualified service personnel. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. Este símbolo tiene el propósito, de alertar al usuario de la presencia de "(voltaje) peligroso" sin aislamiento dentro de la caja del producto y que puede tener una magnitud suficiente como para constituir riesgo de descarga eléctrica. Este símbolo tiene el propósito de alertar al usario de la presencia de instruccones importantes sobre la operación y mantenimiento en la información que viene con el producto. [. . . ] (note to structural engineer) For the Impulse® 100P the thread insertion depth of the end of the mounting bolt should not be more than 5/16" past the surface of the cabinet. If these thread insertion depths are exceeded, then the inserts may be damaged or unseated from the cabinet, severely compromising the mounting integrity of the cabinet!The correct mounting bolt diameter and threads per inch are: 1/4" x 20. Use of a grade five bolt is recommended. GETTING AC POWER TO THE IMPACT 1 The Impulse 100P comes with an 8 foot 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 that the extension cord is no longer than necessary, and is 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 100P's internal amplifiers. For best results, do not power anything else from the extension cord used to power the Impulse 100P, in order to 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; this seriously compromises safety. USE OF IMPACT 1 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. If so, it may have triggered the thermal protection. Turn off the unit, and cool as best as the situation allows (DO NOT use liquids for this purpose!) If there is still no output, it may help to read the owner's manual completely. Hum or Buzz This can be AC outlet related. Try plugging the Impulse 100P into a different AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and the Impulse 100P, it can cause hum problems. Check to make sure that shielded cables have been used to get the signal to the Impulse 100P's inputs. Speaker cables with 1/4" or XLR plugs will be very prone to hum. Check to make sure light dimmers are not on the same circuit as the Impulse 100P or the mixer (or any source devices). If light dimmers are in use, then it may be necessary to turn them full on or fully off to eliminate or reduce hum to tolerable levels. This is an AC wiring/light dimmer interference problem, and not the fault of the Impulse 100P. The third wire ground plug on the AC plug should NEVER be removed or broken off, this seriously compromises safety. [. . . ] Also has a ??" phone jack based loop-thru that allows other Impulse 100P units to be linked to a single unit for signal source and volume control. Enclosure materials and finish: Injection-molded high-impact polypropylene of a nominal thickness of 1/4" with internal ribbing and bracing, and with textured finish. Mounting: Subwoofer stand mounting via molded-in mount, flying via VersamountTM 35 (top or bottom of cabinet) and four rubber feet for floor use.
