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 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 1282.
However, the combined weight of additional
enclosures and all cables, clamps, and other
hardware must not exceed 147 lbs. The
Impulse 1282 weighs 54 pounds and the
maximum combined weight suspended from
the uppermost mounting bracket assemblies
must not exceed 200 pounds. Maximum
enclosure angle is 45

. Use only 1/2" forged
