O V E R V I E W
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.

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 BiDATTM (Bi-directional Data-over-Audio Transceiver) communication system ensures that correct instructions are sent and messages received across the signal cables.

Switch-Mode Power Supply
Figure 2 - EVOi.324 Rear
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.

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.

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.

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 equalization has been applied to the signal) for maximum performance. 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: 115V~ T6.3A/250V~ 230V~ T3.15A/250V~

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 shutdown 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.

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.

LOUDSPEAKER BASICS
EVO Sound System Design Basics
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.)

EVOi.324 Coverage Angles
Placing this 80° x 80° speaker up in the air and pointing it towards an audience area will result in a defined area of coverage.
Figure 10 - Area of Coverage
Out of Coverage
The Throw Ratio Based on its area of coverage performance, the EVOi.324 has a height-to-depth Throw Ratio of 1:3. This Throw Ratio can be used to optimally position the loudspeaker. For example, if the EVOi.324 is installed at a height of 10', it will "throw" to a distance of 30' away from the loudspeaker and hence provide optimized coverage up to 30' away. Refer to Table 1 and Figure 11 below to identify either: i. The throw (optimized coverage distance), for a given fixed (pre-determined) height above the floor. ii. The installation height necessary to provide the desired throw (optimized coverage distance).

Note that this area of coverage actually includes three different areas: an area of "optimized coverage" (black); an area of "reduced loudness" (gray); and an area "out of coverage" (white). Understanding the optimum performance of the EVO Loudspeaker through the use of a simple Throw Ratio and Aiming guide line will help you achieve optimized coverage over your defined listening area.

Aiming EVO
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. For example, if the EVOi.324 is installed at a height of 10', it will "throw" to a distance 30' away provided it is aimed to a point 20' away. Refer to Table 1 and Figure 11 on page 9. Maximum Performance Guideline You may have noted from Table 1 that the guide does not provide figures above a 40' installation height. Above a height of 40' the useful throw and optimized coverage area will not grow, in fact it will probably start to deteriorate depending on the natural acoustics of the room. The guidelines below can be used to determine the maximum performance achievable for a given loudspeaker height above the listening area. Program Requirement Speech only Speech + acoustic music Amplified live music Loud, playback music Maximum Height 40' 40' 20' 20' Maximum Throw 120' 120' 60' 60'
Using More Than One Speaker
Stereo and Arrays So far we have discussed the simplest sound reinforcement system configuration, a single EVO loudspeaker. Most applications will require the use of more than one EVOi.324, either because a stereo Left Right effect is required (see Figure 12)...

When to use Delay Speakers
The use of more than one EVOi.324 may be necessary in venues with extremely long listening areas. For example if the listening area is 120' in depth and the required performance is for "Loud Playback Music" the Maximum Performance Guideline on page 10 indicates a maximum 20' installation height. This will provide 60' of throw. To cover the remaining 60' of listening area, a second auxiliary/delay speaker is required (see Figure 15). Note that the sound from the delay speaker must be "in sync" with the sound from the main speaker. This is achieved by appropriately delaying the audio signal arriving at the delay speaker and also by reducing its overall output level. While these adjustments typically require the use of complex measurement equipment, expensive delay devices and years of audio experience, they can be made automatically through the use of the optional EVOi.net controller.

As a guide this section provides some typical configurations for EVOi.324 installations, the approximate locations of each EVOi.324 and the aiming position in the room. Please note that when the installation requires the additional support of an auxiliary (Delay) EVOi.324s to cover larger listening areas, the use of EVOi.net is highly recommended as this will access the automated "delay-set" feature.
EVOi.324s IN RECTANGULAR ROOMS
Small Rectangular Room: 1 Main (Mono)
This is the simplest configuration. In this example, figure 16, one EVOi.324 will cover the entire listening area. Stereo is not required, as this system is predominantly used to reinforce speech only. The EVOi.324 is positioned 20' above the floor and aimed to a point 40' away on the central axis of the room. Optimum coverage will be provided up to 60 feet away.

For a wider room or where a stereo program is required each EVOi.324 should be aimed according to the 1:3 "throw ratio" described in the previous section (page 8 & 9). In this example, the EVOi.324s are positioned 20' high and aimed 40' away. They will provide optimum coverage up to 60' away. In addition, they should both be aimed at a single point 40' away, the central axis of the room, as seen in Figure 18.

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.
2. Prepare all surfaces by wiping off dust and cleaning with a damp cloth. It may be necessary to use a mild household cleaner to remove grease. 3. Carefully mask the aluminum electronics enclosure on the back of the speaker. IT SHOULD NOT BE PAINTED. Removal of the electronics enclosure should only be done by qualified service personnel. 4. Carefully mask the baffle area. Avoid getting paint on the loudspeaker cones or in the waveguide. It's not a good thing. 5. Apply as many coats of paint as is required. Standard household or industrial paints (i. e. waterbased latex or enamel) will provide the best results. Spraying many thin coats will provide the best results. 6. Assemble the EVOi.324 in reverse order as described in Step One.
Instructions for Painting:
1. It is strongly recommended that EVOi.324 be partially disassembled to obtain optimum results. This requires removing the grill, the handle bar, and suspension point placeholder screws. A. Remove the grill screw covers by gently prying off. B. Remove six grill retain screws. C. Remove four allen head screws from the grill frame. D. Remove the grill taking care to keep the grill and grill supports together. E. Remove all six suspension placeholder screws. F. Remove the four allen screws retaining the handle bar and remove the bar.

Overview
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. Always consult a qualified person.
For Example: Maximum Load Rating divided by EVOi.324 Net Weight = The number of speakers in a vertical array. 142.8 lb (67.8 Kg) / 65 lb (29.5 Kg) = 2.1 Therefore only two EVOi.324s may be used in a vertical array if they are suspended from the points located on the top of the enclosure in either recommendations 1 and 2 stated above.
Suspension
WARNING !! Suspending this system should be done by qualified persons following safe rigging standards. For more information, please refer to the JBL Technical Note Volume 1, Number 14 Basic Principles for Suspending Loudspeaker Systems. Before suspending an EVOi.324, be sure to inspect all components for cracks, deformations, corrosion, and/or missing or damaged parts that could reduce the strength and safety of the installation. Perform all calculations to ensure that all components are used within their rated work load before suspending an EVOi.324. Remember the weakest component determines the size and safety of the entire installation. There are 3 suspension points on the top and bottom of EVOi.324, two toward the front of the enclosure and one to the rear. Pull tests at a certified test facility have documented non-catastrophic failure at 450 550 pounds for each individual front suspension point and 1000 pounds for the rear suspension point. It is recommended that EVOi.324 be either suspended: 1. Equally from both of the front suspension points together, or 2. From the rear suspension point, with the addition of a safety cable to another suspension point. For both recommendations, assuming a 7:1 safety factor, the load on the suspension points should NEVER be greater than 142.8 pounds (67.8 Kg).

Foot 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. Parts Included: 2 x Small Rubber Feet 1 x Large Rubber Foot, threaded with nut 1 x Washer Installing Feet: i. Remove suspension insert screws from the bottom of the enclosure.
iv. Screw the large rubber foot into the suspension position for the required aiming angle. For example, screw it all the way in and EVOi.324 will aim up slightly. Unscrewing it will begin to tilt EVOi.324 down. v. Important: Once the large rubber foot is positioned correctly tighten the nut onto the washer. This will ensure the weight is transferred to the enclosure and not the suspension insert.

ii. Using two of the removed suspension placeholder screws attach the small rubber feet to the front suspension positions. Please note that there is an orientation to the small rubber feet which compensates for the angle of the enclosure surface. iii. Place the large washer over the rear suspension position. Make sure the nut is threaded onto the large rubber foot. Then insert the threaded portion through the washer and into the rear suspension position.

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. Application of the AC Mains power will result in the EVOi.324 starting up and initializing (boot process takes about 20 seconds). There is a slight power draw even when EVOi.324 is not passing audio (approximately equivalent to a 100W light bulb (see AC Power requirements page 21). It may be desirable to place a switch on its circuit. This switch should be appropriately rated and installed by a competent electrician in full compliance with all applicable national and local electrical codes. 1. EVOi.324 doesn't power up: i. Is it plugged in? ii. Is the AC Mains circuit adequate for system and energized? Due to the highly efficient nature of the electronics, there will be a direct correlation between signal level and current draw. While it may be possible to start multiple systems on one AC circuit, continued high level operation may result in occasional brown-outs (see AC Power Requirements on page 21).
3. EVOi.324 powers up, the LED on rear panel lights up, but doesn't pass audio: i. Less than 20 seconds have passed. Wait for a couple of moments as EVOi.324 Boots-up. ii. Check that there is audio signal present: - Is there a signal cable connected? If so, check that it is not defective. - Is there signal coming out of the mixer? - Is EVOi.net attached? (See EVOi.net manual.) iii. If none of the above then immediately contact your Dealer.
4. The system doesn't get any louder no matter how much the input signal is turned up: i. Is it really loud already? Built-in limiters are specially calibrated to prevent damaging levels to the individual speakers in EVOi.324. These limiters are designed to be as transparent as possible while still providing necessary protection functionality. It doesn't get any louder because it is working, protecting itself!
2. The Power LED is Flashing: i. The AC Main voltage is inadequate or out of the rated range (see AC Power requirements page 21). ii. The AC Mains is not appropriate for the model (i.e. 120V model for 120V service). Check the voltage stated on the rear input label and return to the Dealer if incorrect. iii. The fuse may have blown. CAUTION: to reduce the risk of fire, replace the fuse with the same type and rating. iv. If none of the above then immediately contact your Dealer.
5. The sound system is making a terrible noise: i. If a microphone is being used in the system you may be hearing feedback. Turning down the level of the microphone and/or repositioning it may help. Using EVOi.net you can start the Anti Feedback control built into EVOi.324. ii. Is tape deck playback level up? Electrical feedback may be present. Try lowering the tape deck playback level. Check that the tape deck is not connected to the record outputs.

AC Power Requirements
In the United States, the EVOi.324 is supplied with an Edison type plug. For other countries, the correct plug must be used in accordance with the local requirements. For Europe and the rest of the world the correct AC supply lead will be supplied. Voltage Requirements EVOi.324 will operate continuously provided the AC Voltage falls within the following ranges: Standard AC Voltage 120v 230v Voltage Range +/- 10% +/- 10% Frequency 50/60Hz 50/60Hz
Current Requirements EVOi.324 will not draw a continuous current. Acting as a dynamic load on the AC supply, the current drawn will vary dependant on the operating level, e.g. quiet levels and loud levels in the program. Understanding the amount of current drawn is essential when using EVOi.324. The EVOi.324 is capable of drawing peak currents of up to 18 Amps. Any cabling used should be of a suitable gauge to reflect this. Inadequate cabling can cause large voltage drops over distance and potentially cause `brown-out'.
ALWAYS CONSULT A QUALIFIED ELECTRICIAN Brown-out Conditions If the voltage falls below this range, the EVOi.324 will `brown-out'. During `brown-out' the audio signal will momentarily mute during very high level program. Should the supply voltage permanently remain below this supply voltage, then the EVOi.324 will shut down. When the AC supply falls within the above stated ranges, EVOi.324 will switch on again, and operate normally. To avoid `brown-out' EVOi.324 should be operated with an AC supply that adequately falls within the above stated ranges.
