Description
The new Pe vey ILS 1264V (vertic l)
Loudspe ker System is two-w y,
vented low frequency enclosure using
12" low frequency driver p ired with
60° (horizont l) by 40° (vertic l) high
frequency w veguide. The HF section
employs 1.6 exit/100mm voice coil
compression driver mounted on one of
Pe vey’s revolution ry new Qu dr tic
Thro t w veguides. The ILS 1264 h s
full r nge sensitivity of 96 dB SPL –
(1 w tt/1 meter) nd m ximum output
of 130 dB t 1 meter (full r nge).
The Pe vey ILS 1264 is high
perform nce loudspe ker system for
use in dem nding sound reinforcement
pplic tions. The robust construction of
the ILS 1264 provides power h ndling
c p cities of 700 W continuous, 1.4 kW
progr m nd 2.8 kW pe k (full r nge).
The unit m y be oper ted using the
intern l p ssive crossover or m y be
bi mplified. Twelve 3/8"x16 thre ded
mounting suspension points (three e ch
top nd bottom nd two e ch sides nd
b ck) llow v riety of suspension
configur tions. Multiple units m y be
mounted to form vertic l/horizont l

Frequency Response
This me surement is useful in
determining how ccur tely given
unit reproduces n input sign l. The
frequency response of the ILS 1264 V
is me sured t dist nce of 1-meter
using 1 w tt (into the nomin l
imped nce) swept-sine input sign l.
As shown in figure 1, the selected
drivers in the ILS 1264 V combine to
give smooth frequency response
from 63 Hz - 18.5 kHz.
Directivity
Be mwidth is derived from the -6 dB
points from the pol r plots (see Figure
3) which re me sured in whole
sp ce nechoic environment. Q nd
Directivity Index re plotted for the on-
xis me surement position. These re
specific tions th t provide reference
to the cover ge ch r cteristics of the
unit. These p r meters provide insight
for proper pl cement nd inst ll tion
in the chosen environment. The
blending of the components of the ILS
1264 V exhibit desir ble be mwidth
nd directivity (Figure 3 nd 4)
suit ble for sound reinforcement
pplic tions.
Power Handling
There re m ny different ppro ches
to power h ndling r tings. Pe vey
r tes this loudspe ker system’s power
h ndling using full-r nge form of the
AES St nd rd 2-1984. Using udio
b nd 20 Hz to 20 kHz pink noise with
pe ks of four times the RMS level,
this strenuous test sign l ssures the
user th t every portion of this system
c n withst nd tod y’s high technology
music. This r ting is contingent upon
h ving minimum of 3 dB of mplifier
he droom v il ble.
Harmonic Distortion
Second nd third h rmonic distortions
vs. frequency re plotted in Figures 5
nd 6 for two power levels. Ten
percent (10%) of r ted input power
nd either one percent (1%) of r ted
input power or one w tt, whichever is
gre ter. Distortion is re d from the
gr ph s the difference between the
fund ment l sign l (frequency
response) nd the desired h rmonic.
As n ex mple, distortion curve th t
is down 40 dB from the fund ment l
is equiv lent to 1% distortion.
Mounting
Caution: Before ttempting to
suspend this spe ker, consult
certified structur l engineer. Spe ker
c n f ll from improper suspension,
resulting in serious injury nd property
d m ge. Other enclosures m y be
suspended below one ILS 1264 V.
However, the combined weight of
ddition l enclosures nd ll c bles,
cl mps nd other h rdw re must not
exceed 330 pounds. The ILS 1264 V
weighs 70 pounds nd the m ximum
combined weight suspended from the
uppermost mounting br cket
ssemblies must not exceed 400
pounds. M ximum enclosure ngle
45o. Use only the correct m ting
h rdw re. All ssoci ted rigging is the
responsibility of others.
