User manual PEAVEY IMPACT 2

[. . . ] Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion. compact, weather-resistant package. The enclosure utilizes high-impact polypropylene in an injection-molded plastic trapezoidal shape, along with a coated perforated metal grille to offer a cosmetically elegant yet durable system. The two-way system includes a 12" Black Widow® woofer with a Kevlar® impregnated cone and a specially treated surround, cone and dust cap for excellent weather resistance. [. . . ] The RXTM22 compression driver features a 2" titanium diaphragm, a patented phase plug (U. S. Patent 6, 064, 745), and is coupled to an extremely smooth and well controlled constant directivity horn, with a coverage pattern of 90 degrees by 45 degrees that is molded into the enclosure. Input connection to the system is made via 1/4" phone jacks (2) or 4-pin Neutrik® Speakon® connectors. Provisions for biamplification are made through a 4-pin Neutrik® switching jack. The internal passive crossover features Sound GuardTM to protect the tweeter, and utilizes high performance components and an advanced topology crossover to provide high power handling and a smooth yet clear response. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from 75 Hz to 18 kHz. The free-flow vented cabinet offers mounting point inserts top and bottom as well as a molded-in stand adapter for maximum utility and ease of use. FREQUENCY RESPONSE: This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the Impulse 1012 (8 ohm) is measured at a distance of 1-meter using a 1 watt (into the nominal impedance) swept-sine input signal. The nominal impedance shall be 4. 0 ohms. The maximum continuous power handling shall be 700 watts, maximum program power of 1, 400 watts and a peak power input of at least 2, 800 watts, with a minimum amplifier headroom of 3 dB. The nominal radiation geometry shall be 90 degrees in the horizontal plane and 45 degrees in the vertical plane. The outside dimensions shall be 23. 69 inches high by 17. 81 inches wide by 13. 75 inches deep. The loudspeaker system shall be a Peavey model Impulse 1012 (8 ohm). The 8 ohm loudspeaker system shall have an operating bandwidth of 75 Hz 18 kHz. The nominal output level shall be 100. 0 dB when measured at a distance of one meter with an input of one watt. The nominal impedance shall be 8. 0 ohms. The maximum continuous power handling shall be 500 watts, maximum program power of 1, 000 watts and a peak power input of at least 2, 000 watts, with a minimum amplifier headroom of 3 dB.
