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.

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.

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
LF 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.

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

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.)
