Harmonic Distortion

Second and third harmonic distortions vs. frequency are plotted in Figures 5 and 6 for two power levels. Ten percent (10%) of rated input power and either one percent (1%) of rated input power or one watt, whichever is greater. 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.

vide ultra-high performance in a portable, 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 15" Black Widow® woofer with a Kevlar® impregnated cone and a specially treated surround, cone and dust cap for excellent weather resistance. The RX22 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 Neutrick switching jack. The internal passive crossover features Sound Guardto 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 60 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 1015 is measured at a distance of 1-meter using a 1 watt (into the nominal impedance) sweptsine input signal. As shown in figure 1, the selected drivers in the Impulse 1015 8 ohm combine to give a smooth frequency response from 60Hz - 18 kHz.

DIRECTIVITY:

Beamwidth is derived from the -6 dB points from the polar plots (Figure 3) which are measured in a whole space anechoic environment. Q and Directivity Index are plotted for the on-axis measurement position. 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 Impulse 1015 8 ohm exhibit a desirable beamwidth and directivity (Figure 3 and 4) suitable for sound reinforcement applications.

POWER HANDLING:

There are many different approaches to power handling ratings. Peavey rates this loudspeaker system's power handling using a full-range form of the AES Standard 2-1984. Using audio band 20 Hz to 20 kHz pink noise with peaks of four times the RMS level, this strenuous test signal assures the user that every portion of this system can withstand today's high technology music. This rating is contingent upon having a minimum of 3 dB of amplifier headroom available.

ARCHITECTURAL AND ENGINEERING SPECIFICATIONS:

The 4 ohm loudspeaker system shall have an operating bandwidth of 58 Hz - 18 kHz. The nominal output level shall be 99 dB when measured at a distance of one meter with an input of one watt. 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 95

degrees in the horizontal plane and 70 degrees in the vertical plane. The outside dimensions shall be 28.56 inches high by 21.31 inches wide by 17.00 inches deep. The weight shall be 56 pounds. The loudspeaker system shall be a Peavey model Impulse 1015 4 ohm.

The 8 ohm loudspeaker system shall have an operating bandwidth of 60 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. The nominal radiation geometry shall be 95 degrees in the horizontal plane and 45 degrees in the vertical plane. The outside dimensions shall be 28.56 inches high by 21.31 inches wide by 17.00 inches deep. The weight shall be 56 pounds. The loudspeaker system shall be a Peavey model Impulse 1015 8 ohm.

CAUTION: 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 product or device from this enclosure! Maximum enclosure angle 45o. Use only the correct mating hardware. All associated rigging is the responsibility

of others.
