User manual PEAVEY IMPULSE 200P

[. . . ] The high pass filter/line output of the Sub provides a line level output to an external full range sound system. The 600 watt peak dynamic internal amplifier internal amplifier belts out frequencies as low as 45 Hz ­ incredible for such a compact cabinet. Balanced input and chaining jacks allow for low noise signal transfer even at high levels. (1) FUSE The unit is AC power line fuse protected from overloads and fault conditions with an ABC-type fast-blow five amp fuse. [. . . ] If the bass sound seems heavily compressed, then the Impulse 500P Subwoofer is heavily into DDTTM compression, and the drive level from the mixer (or the volume control on the Impulse 500P Subwoofer) needs to be reduced. When first turning on the sound system, turn on all upstream electronics first, then the Impulse 500P Subwoofer with its volume control fully CCW (all the way down). If sending a signal to a full range powered system, such as the Impulse 500P, turn it on last, with its volume control fully CCW. Begin checking levels with the mixer output level controls all the way down, and bring them up slowly with the Impulse 500P Subwoofer volume control set to the desired setting (1/2 way up recommended to start). HIGH PASS FILTERED OUTPUTS These are low impedance filtered outputs that are provided to send the high frequencies to a powered speaker enclosure such as the Impulse® 500P full range system, or to a conventional power amp and speaker system. The output level is not affected by the volume control on the Impulse 500P Subwoofer. The nominal polarity of these outputs is positive, and can be run directly into the Impulse 500P® for a nearly perfect mesh of the subwoofer with the full range unit. The polarity should also mesh with just about any other powered speaker or amplifier and speaker pair, as long as they observe industry standard polarities. In the event they do not, the balanced output can have pins two and three reversed with the use of an XLR or 1/4" phone cable that swaps these two pins at one end. This will reverse the polarity of the highs coming out of the high pass filtered output, and allow it to be used with equipment that might have polarity reversals. USE OF MULTIPLE IMPULSE 200P SUBWOOFER'S (or other Impulse® series powered products) The provision of multiple parallel high-impedance inputs allows the inputs of the Impulse 500P Subwoofer to be "daisy-chained" from one to the other. 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. This is an AC wiring/light dimmer interference problem, and not the fault of the Impulse 500P Subwoofer. Distorted or Fuzzy Sound: First, make sure the mixer (or signal source) is not clipping or being overdriven. Cleaning Never clean the Impulse 500P 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 500P Subwoofer, as they could attack the polymer that the cabinet is made from. Touchup If the Impulse 500P 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. For an overall finish enhancement and protective coating, use gloves to apply either WD-40® or Armour All® protectant to the surface of the plastic cabinet only. Insert Points (maximum depth of insertion) The insert points on the top and bottom of the cabinet must only be engaged to a depth of 3/8" or less to prevent air leaks if the mounts/bolts are removed later. [. . . ] It should not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. When the provided plug does not fit into your inlet, consult an electrician for replacement of the obsolete outlet. [. . . ]
