EVOi.324 2 INTRODUCTION WELCOME Thank you for purchasing an EVOi.324 Intelligent Powered Loudspeaker . Not only is this the most compact 1300 watt powered loudspeaker , it is also the world’ s first loudspeaker with built-in intelligence.
EVOi.324 3 DESIGN OVER VIEW 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.

EVOi.324 10 LOUDSPEAKER BASICS Aiming EV O Once the optimum height of the EVO loudspeaker has been identified it needs to be aimed to achieve the desired coverage area. The point at which to aim is derived from a simple height-to-depth aiming ratio of 1:2.
EVOi.324 11 APPLICA TIONS LOUDSPEAKER BASICS W hen to use Delay Speak er s The use of more than one EVOi.324 may be necessary in venues with extremely long listening areas.
EVOi.324 12 APPLICA TIONS EVOi.324s IN RECT ANGULAR ROOMS Small Rectangular R oom: Longer R ectangular Room: 1 Main (Mono) + 1 Delay (Mono) For a longer room additional coverage will be required to cover the back rows of the listening area. This can be achieved using an additional auxiliary (Delay) EVOi.
EVOi.324 13 APPLICA TIONS EVOi.324s IN RECT ANGULAR ROOMS Longer/W ider Rectangular R oom: 2 Main (Stereo) + 2 Delay (Ster eo) For additional coverage in a longer room, two more auxiliary (Delay) EVOi.324s can be used, positioned and aimed as shown in Figure 19.
EVOi.324 14 APPLICA TIONS EVOi.324s IN RECT ANGULAR ROOMS Lar ger/W ider R ectangular Rooms: 2 Main (Mono Ar r ay) + 2 Delay (Mono Ar ray) In a wide room where a stereo program is not necessary the Main and Delay EVOi.324s can be configured into Arrays for broader coverage and supplied with a mono signal.
EVOi.324 15 APPLICA TIONS EVOi.324s IN FAN SHAPED ROOMS Small Fan Shaped R oom: 1 Main (Mono) Like the small rectangular room, a simple configuration of one EVOi.324 will provide enough coverage for the entire listening area. Stereo is not required, as this system is predominantly used to reinforce speech only .
EVOi.324 16 APPLICA TIONS EVOi.324s IN FAN SHAPED ROOMS Lar ge F an Shaped Room: 2 Main (Mono Ar r ay) + 2 Delay (Mono) A larger version of the previous example, Figure 23, illustrates the positioning of two Delay EVOi.324s to cover the listening area that falls outside the optimum coverage of the Main EVOi.
EVOi.324 17 P AINTING EVOi.324 is readily paintable. The SMC (Sheet Molded Compound) provides a lightly textured surface that any standard household or industrial paint readily adheres to. The result is a sound reinforcement system that is able to blend unobtrusively into the decor of its environment.
EVOi.324 18 INST ALLA TION Ov er view EVOi.324 has been designed to be permanently installed. An eyebolt kit has been provided to facilitate suspension from above: a ceiling, a beam or overhang. EVOi.324 weighs 65 pounds (29.5 Kg) and attaching this loudspeaker to a surface is a task that should not be taken lightly .
EVOi.324 19 INST ALLA TION F oot Kit The Foot Kit must be utilized if EVOi.324 is to be used “ Free Standing ” . It provides a much more stable base and also a mechanism that compensates for the shape and angle of the bottom of the enclosure.
EVOi.324 20 The EVOi.324 loudspeaker system has been precision engineered for optimum performance with a minimum of maintenance and outside intervention. AC Power The EVOi.324 speaker contains a high-powered amplifier system. Due to the remote locations likely for install, there is no power switch.
