DESCRIPTION: The Impulse 500 is a two-way full-range speaker system engineered to provide ultra-high performance in a portable, compact, weather-resistant package. The enclosure utilizes high-impact polypropylene in an injection-molded plastic trape-

10k 20k 2nd Harmonic 3rd Harmonic Figure 5 HARMONIC DISTORTION Second and third harmonic distortion vs. frequency is plotted in two power levels: one tenth of rated input power and either one one hundredth of rated input power or 1 Watt, whichever is higher. Distortion is read from the graph as the difference between the fundamental signal and the desired harmonic. As an example, distortion that is 40 dB down from the fundamental signal is equivalent to 1% distortion. Harmonic Distortion at 1/10 Rated Power dB SPL (re 20 Pa)

FREQUENCY RESPONSE: This measurement is useful in determining how accurately a given enclosure reproduces an input signal. The frequency response of the Impulse 500 is measured at 1 meter using a 2.82volt, swept-sine input. The selected driver in the Impulse 500 combine to give a smooth frequency response from 62 Hz to 18 kHz. DIRECTIVITY: Beamwidth and directivity factors are derived from the -6 dB points from the polar plots (see figure 3), which are measured in a whole space anechoic environment. These are specifications that provide a reference to the coverage characteristics of the unit. These parameters provide insight for proper placement and installation in the chosen environment. The blending of the components of the Impulseª 500 exhibit a desirable beamwidth and directivity (figures 3 and 4) suitable for sound reinforcement applications.

zoidal shape, along with a coated perforated metal grille to offer a cosmetically elegant yet durable system. The two-way system includes a 15" Black Widow woofer with a Kevlar¨ impregnated cone and a specially treated surround, cone and dust cap for excellent weather resistance. The 22XT compression driver features a 2" titanium diaphragm, 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 bi-amplification are made via a lock-down switch selected mode of operation for the Neutrik connectors, or instant access 1/4" switching jacks. The internal passive crossover features Sound Guard 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 62 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. 20k POWER HANDLING: There are many different approaches to power handling ratings. Peavey rates this speaker systemÕs power handling using a modified form of the AES Standard 2-1984. Utilizing audio band 20 Hz to 20 kHz pink noise with peaks over four times the RMS level, this strenuous test signal assures the user that every portion of this system can withstand todayÕs high technology music. The test signal contains large amounts of very low frequency energy, effectively simulating the frequency content of live music situations. The full measure of high frequencies in the test signal allows for exposure of the speaker to synthesized tones that may extend beyond audibility. This rating is contingent on having minimum 3 dB of amplifier headroom available.

ARCHITECTURAL AND ENGINEERING

SPECIFICATIONS: The loudspeaker system shall have an operating bandwidth of 48 Hz to 18 kHz. The output level shall be 100 dB when measured at a distance of 1 meter with an input of 1 watt. The nominal impedance shall be 8 ohms. The continuous power handling shall be 350 watts, maximum program power of 700 watts, and a peak power handling of 1,400 watts, with a minimum amplifier headroom of 3 dB. The peak SPL with inaudible distortion shall reach 133 dB with music as a source, when measured at a distance of 1 meter and driven to rated power. The system shall utilize a 15" Black Widow woofer and a 22XT compression driver tweeter. The nominal radiation pattern shall be 90 degrees in the horizontal plane and 45 degrees in the vertical plane. The cabinet is to consist of injection-molded polypropylene of 1/4" nominal thickness, with internal reinforcing ribs. A handgrip shall be present on each side of the cabinet next to the woofer and a handle 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 top and bottom for flying use. The outside dimensions shall be 28 9/16" tall by 21 5/16" wide (11 1/2" wide in rear) by 17" deep. The weight shall be 56 lbs. The input connection shall be made available via two 1/4" phone jacks and two 4-pin Neutrik Speakon connectors, all connected in parallel for full range use, and a locking switch to select bi-amp use for the Neutrik connectors and instant access 1/4" switching jacks for bi-amp use with 1/4" phone jacks. The loudspeaker system shall be a Peavey model Impulse 500. Warning! When use of a stand is considered, the Peavey S-1ª stand is recommended. Other stands may not have a base sufficiently wide enough for stability and safety. CAUTION! For permanent outdoor installation, avoid direct cone exposure to sunlight and rain by tilting speaker down and use a splash shield on top. WARNING! Before attempting to suspend this speaker, consult a certified structural engineer. Speaker can fall from improper suspension, resulting in serious injury and property damage. Do not suspend or mount any other product or device from this enclosure! Use only Grade 5 hardware or better. Kevlar¨ is a registered trademark of DuPont Company.
