Description

The new Peavey ILS 1294V (vertical)

Loudspeaker System is a two-way,

vented low frequency enclosure using

a 12" low frequency driver paired with

a 90° (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 1294 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 1294 is a high

performance loudspeaker system for

use in demanding sound reinforcement

applications. The robust construction of

the ILS 1294 provides power handling

capacities of 750 W continuous, 1.5 kW

program and 3.0 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 (3 each top

and bottom and 2 each sides and back)

allow a variety of suspension

dimensions shall be 27.00 inches high

by 19.38 inches wide by 17.75 inches

deep. The weight shall be 70 pounds.

The loudspeaker system shall be an

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.

Frequency Response

determining how accurately a given

unit reproduces an input signal. The

frequency response of the ILS 1294V

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 1294V combine to

give a smooth frequency response

from 63 Hz — 18.5 kHz.

Mounting

Caution: Before attempting to

suspend this speaker, consult a

certified structural engineer. The

speaker can fall from improper

suspension, resulting in serious injury

and property damage. Other

enclosures may be suspended below

one ILS 1294V. However, the

combined weight of additional

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.

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

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 90^oin the horizontal plane and 40^o
