array [see limitations under mounting
instructions]. Both versions of the ILS
1264 are solidly constructed of 3/4"
void free poplar plywood and finished
with an exterior grade hardened black
paint.
Frequency Response
This measurement is useful in
determining how accurately a given
unit reproduces an input signal. The
frequency response of the ILS 1264 V
is measured at a distance of 1-meter
using a 1 watt (into the nominal
impedance) swept-sine input signal.
As shown in figure 1, the selected
drivers in the ILS 1264 V combine to
give a smooth frequency response
from 63 Hz - 18.5 kHz.
Directivity
Beamwidth is derived from the -6 dB
points from the polar plots (see 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 ILS
1264 V 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.
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.
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 ILS 1264 V.
However, the combined weight of
additional enclosures and all cables,
clamps and other hardware must not
exceed 330 pounds. The ILS 1264 V
weighs 70 pounds and the maximum
combined weight suspended from the
uppermost mounting bracket
assemblies must not exceed 400
pounds. Maximum enclosure angle
45
o . Use only the correct mating
hardware. All associated rigging is the
responsibility of others.
