user that every portion of this system can withstand today’s 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 allow for exposure of the speaker system to synthe- size tones that may extend beyond audibility. This rating is contingent on having a minimum 3 dB of amplifier headroom available.

HARMONIC DISTORTION

Second and third harmonic distortion vs. frequency are plotted in Figures 5 and 6 for two power levels, one-tenth rated input power and one-hundredth rated input power. 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.

MOUNTING:

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. Other enclosures may be suspended below one Impulse 1582. However, the combined weight of additional enclosures and all cables, clamps, and other hardware must not exceed 117 lbs. The Impulse 1582 weighs 108 pounds and the maximum combined weight suspended from the uppermost mounting bracket assemblies must not exceed 225 pounds. Maximum enclosure angle is 45°. Use only 1/2" forged shoulder machinery eyebolt, mil spec. MS51937-5, Peavey part number 00332250. All associated rigging is the responsibility of others.
