DESIGN O ER IEW

The EVOi.324 has been designed specifically for fixed

installation applications. EVO is intended to be used where

high quality state-of-the-art sound reinforcement is

required, in venues such as performing arts centers,

worship spaces, educational multi-purpose rooms and other

civic venues.

It has been engineered to provide premium performance

with minimal visual impact. EVOi.324 speakers adapt to

internal décor with a paintable surface and to low ceilings

by offering the same performance in a vertical and

horizontal configuration.

Installation and setup are quick and simple to understand.

This is the fundamental principle of the EVO system,

whereby the majority of problems in system installation

and set-up are eliminated because the most complex

elements have already been designed into the loudspeaker.

1 J L Eyebolt System

Located on the top (and bottom) is our standard JBL eyebolt

system to accommodate ceiling attachment (and floor

mounting system, see Foot Kit, page 19), when required.

2 14” LF/MF Transducers

Each 14-inch, LF (Low Frequency) and LF/Mid carbon-

fiber cone transducer features our patented dual-coil, dual-

gap Neodymium Differential Drive (NDD™) technology

for 1/5th the weight of conventional ferrite transducers with

twice the power handling. Moreover, each transducer is

driven by its own 600 watt D-class (digital) amplifier.

Figure 1 - E Oi.324 Front & Top

(Grill removed for clarity)

3 Thermomaster

Vents

Each respective baffle vent, woofer motor, and basket are

all linked via the same thermal transfer path for maximum

heat dissipation. Taking heat away from the voice coil

effectively reduces power compression. The harder the

system works, the better it cools.

4 2430 Compression Driver

The JBL 2430 neodymium large-format compression driver

has a 1.5-inch exit and 3-inch voice coil with 100 watt

power handling. The revolutionary neodymium motor

structure results in an extremely compact and lightweight

HF (High Frequency) transducer, weighing only 2.5 lbs.

The JBL 2430 driver is powered by an internal 100 watt

linear amplifier.

5 Aluminum Waveguide

The aluminum waveguide effectively couples the JBL 2430

driver to the outside world. It works with the LF/MF and

transducers and our Filtered Array Technology (FAT™)

to achieve a constant 80°x 80°horizontal and vertical

coverage pattern.

6 Integrated affle

Our integrated transducer baffle and inertia grounding

straps are designed to lock all the components together,

maximizing acoustic output. The entire baffle area acts as

an open thermal window through which heat is allowed to

escape.

7 SMC Enclosure

The rear enclosure, fabricated from SMC (Sheet Molding

Compound), is in the form of a 2nd-order geometric design

for inherent strength, acoustic architecture, and transparent

aesthetics.

SMC Grille (not shown)

It looks like cloth, but it’s actually an anti-resonant, SMC-

reinforced, expanded steel grill, with an enhanced high

frequency spreading effect.

8 Compact Design

EVOi.324’s design has been dedicated to applications

requiring a permanent sound reinforcement solution. For a

1,300-watt Intelligent Powered Speaker System, it weighs

only 65 pounds (29.5 kg) and stands barely 42” (1.07

meters) tall.

9 D-Class Amplifier

Each EVOi.324 includes two digital amplifiers that are

extremely efficient. The energy from the power supply is

rapidly switched into each loudspeaker. The audio signal is

created as modulated pulses with switching rates many times

faster than the highest audio frequency. Because energy only

flows when needed, losses are substantially reduced as

compared to an equivalent sized conventional amplifier.

10 Handle/Grip

As an aid for setup, the EVOi.324 is equipped with a built-

in carrying handle and grip.

11 XLR Audio / Communication

Input

EVO’s ‘brain’is found in the EVOi.324. All transducer

controls and complex computational system functions take

place on the DSP (Digital Signal Processor) circuit board

within the aluminum housing. Working in tandem with the

optional EVOi.net, each EVOi.324 adapts to its acoustic

environment by generating its own test sequence, including

Auto-EQ and Delay Set settings. With Anti Feedback

Control, it also discriminates between feedback and

program music.

Hook-up is easy – simply use a standard XLR signal cable

to connect from an open EVOi.net Male XLR output (or

output from a mixer – see page 6) to the EVOi.324’s

Female XLR. No other cables are required. An internal

BiDAT™ (Bi-directional Data-over-Audio Transceiver)

communication system ensures that correct instructions are

sent and messages received across the signal cables.

12 Switch-Mode Power Supply

EVOi.324 uses a compact, lightweight, and highly efficient

digital power supply that does not require a large, heavy

toroidal transformer. This low-loss technology utilizes

digital modulation to regulate and supply the voltage

necessary to drive 1,300 watts of power amplification.

Insert the enclosed power cord into the IEC connector to

supply the specified AC power. (See “Hook-up Details” on

page 6 for more information.) The removable fuse protects

internal circuits. When replacing it, be sure to use the same

type as specified.

AUDIO AND AC POWER CONNECTIONS

Power Cycle (Boot-up) Times

EVOi.324’s internal DSP (Digital Signal Processor) circuit

board includes software applications. Like any device

operating software programs, there is a “boot-up” time lag

before EVOi.324 becomes fully operational. The audio

signal will be muted until the loudspeaker is fully

booted up. This should take approximately 20 seconds.

Upon connecting AC mains, the green

power indicator will illuminate. After

approximately 20 seconds there will be a

very quiet click as the system releases the

mute. Upon power disconnection, the

green power indicator will flash several

times, however signal shut-down is

instantaneous. In summary, boot-up time

is approximately 20 seconds and shut-

down time is 0 seconds.

WARNING! When EVOi.324 is on,

the amplifier heatsink will get hot

even when no signal is being passed.

This is normal operation for D-Class

amplifiers.

Maximum Drive Level = +10 dBu * Sensitivity

There are three simple audio hook-up options: all require

the use of high quality balanced signal cable with a Male

XLR connector. EVOi.324 requires a drive level of +10

dBu (sensitivity = +10 dBu assuming no external equaliza-

tion has been applied to the signal) for maximum perfor-

mance. Hooking a microphone directly to the input will

NOT drive it sufficiently. The output of a standard mixer,

EVOi.net or EVOi.sys should provide the optimum drive

level. (See the Sensitivity Chart in the Appendix, page 21)

Power Requirements

IMPORTANT: Each individual EVOi.324 is an extremely

powerful system and is quite capable of drawing peak

currents of up to 18 amps. Please consult a qualified

electrician for correct installation and power connection.

For more information, see AC Requirements on page 21.

CAUTION: to reduce the risk of fire, replace fuse with

same type and rating: ATTENTION: utiliser un fusible de

rechange de meme type de:

APPLICATIONS

INTENDED APPLICATIONS

EVO Loudspeaker Systems have been optimized for small to mid-size venues, where a pair will sufficiently reinforce

sound for an audience of up to five hundred people. They have been designed with specific applications in mind: schools

and sports facilities; places of worship; and performance venues. Typically the program of events are quite varied and high

quality reinforcement is required for speech, live music and recorded music playback. Figures 4-7 below show some typical

type venues and an identifiable area that requires sound reinforcement, we identify this as the listening area. This section

describes how to optimize the placement and position of the EVO Loudspeaker in these typical applications in order that the

entire listening area receives good sound. These are very simple instructions and are for ideal situations.As guidelines, they

are approximate and it may not be possible to follow them in all situations. In the end, final aiming decisions must be based

on what is actually heard when walking the room. Use your ears.

EVO Sound System Design asics

The primary function of a sound reinforcement system is to make sure that all of the listeners in a given audience area are

able to understand the speech and/or lyrics that are being reinforced. The intelligibility of a loudspeaker system is a measure

of how “understandable” its output is. Intelligibility is optimized when the sound radiated from the loudspeaker is primarily

directed to the audience areas and away from microphones and reflective surfaces in the room.

In order to ensure that the radiated sound is directed primarily to the audience areas, great care must be taken in deciding on

loudspeaker placement and aiming. Understanding a loudspeaker’s coverage angles and the proper application of those

coverage angles is the first step towards designing a great sound reinforcement system.

EVOi.324 Coverage Angles

The majority of the sound coming from the EVOi.324 loudspeaker radiates at an angle of 80 degrees in the speaker’s

horizontal (side-to-side) plane and 80 degrees in the speaker’s vertical (top-to-bottom) plane. (Figures 8 and 9.)
