Description

The new Peavey ILS 1564V (vertical)

and ILS 1564H (horizontal) Loud-

speaker Systems are two-way, vented

low frequency enclosures using a 15

inch 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. In the ILS 1564H

unit, the waveguide is rotated to provide

a corresponding beamwidth which may

be employed in low ceiling type

applications. Both versions of the ILS

1564 have a full range sensitivity of

95 dB SPL – (1 watt/1 meter) and a

maximum output of 130 dB at 1 meter

(full range).

The Peavey ILS 1564 is a high

performance loudspeaker system for

use in demanding sound reinforcement

applications. The robust construction of

the ILS 1564 provides power handling

capacities of 750 w continuous, 1.5 kW

program and 3 kW peak (full range).

The unit may be operated using the

internal 1,600 Hz passive crossover or

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.

ILS 1564 are solidly constructed of

3/4 inch void free poplar plywood and

finished with an exterior grade

Architectural and Engineering

Specifications

The loudspeaker system shall have

an operating bandwidth of 47 Hz -

18.5 kHz. The nominal output level

shall be 95.0 dB when measured at a

distance of one meter with an input of

one watt. The nominal impedance

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 1564

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 1564 combine to

give a smooth frequency response

from 47 Hz - 18.5 kHz.

Harmonic Distortion

Second and third harmonic distortions shall be 8.0 ohms. The maximum

vs. frequency are plotted in Figures 5

and 6 for two power levels. Ten

continuous power handling shall be

750 watts, maximum program power

of 1,500 watts and a peak power input

of at least 3,000 watts, with a

minimum amplifier headroom of 3 dB.

The nominal radiation geometry shall

be 70 degrees in the horizontal plane

and 65 degrees in the vertical plane.

The outside dimensions shall be

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.

ILS 1564.

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

1564 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 1564.

However, the combined weight of

additional enclosures and all cables,

clamps and other hardware must not

exceed 304 pounds. The ILS 1564

weighs 96 pounds and the maximum

combined weight suspended from the

uppermost mounting bracket
