Description

The new Peavey ILS 1264H

(horizontal) Loudspeaker System is a

two-way, vented low frequency

enclosure using a 12" low frequency

driver paired with a 60° (horizontal) by

40° (vertical) high frequency

waveguide. The HF section employs a

1.6 exit/100 mm voice coil compression

driver mounted on one of Peavey’s

revolutionary new Quadratic Throat

waveguides. The ILS 1264 has a full

range sensitivity of 96 dB SPL –

(1 Watt/1 meter) and a maximum output

of 130 dB at 1 meter (full range).

The Peavey ILS 1264 is a high

performance loudspeaker system for

use in demanding sound reinforcement

applications. The robust construction of

the ILS 1264 provides power handling

capacities of 700 W continuous, 1.4 kW

program and 2.8 kW peak (full range).

The unit may be operated using the

internal passive crossover or may be

biamplified. Twelve 3/8" x 16 threaded

mounting suspension points (2 each

top, bottom and back and 3 each sides)

allow a variety of suspension

configurations. Multiple units may be

mounted to form a vertical/horizontal

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.

today’s high technology music. This

rating is contingent upon having a

minimum of 3 dB of amplifier

headroom available.

Frequency Response

Architectural and Engineering

Specifications

This measurement is useful in

determining how accurately a given

unit reproduces an input signal. The

frequency response of the ILS 1264H

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 1264H combine to

give a smooth frequency response

from 63 Hz - 18.5 kHz.

The loudspeaker system shall

have an operating bandwidth of 63 Hz

- 18.5 kHz. The nominal output level

shall be 96.0 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

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 60 degrees in the horizontal plane

and 40 degrees in the vertical plane.

The outside dimensions shall be

17.50 inches high by 30.75 inches

wide by 17.50 inches deep. The

weight shall be 80 pounds. The

loudspeaker system shall be an

Architectural Acoustics model ILS

1264H.

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.

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 1264H

exhibit a desirable beamwidth and

directivity (figure 3 and 4) suitable for

sound reinforcement applications.

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 1264H.

However, the combined weight of

additional enclosures and all cables,

clamps and other hardware must not

exceed 320 pounds. The ILS 1264H

weighs 80 pounds and the maximum

combined weight suspended from the

uppermost mounting bracket

WARRANTY

warranty statement. Copies of

Mississippi 39301-2898.

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

assemblies must not exceed 400

pounds. Maximum enclosure angle is

45^o. Use only the correct mating

hardware. All associated rigging is the

responsibility of others.
