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.
