8Compact 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.

10 Handle/Grip

As an aid for setup, the EVOi.324 is equipped with a built- in carrying handle and grip.

11XLR 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.

12Switch-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.

9D-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.
