CHAPTER 1 Introduction Introduction The Electro-Voice EVU series is a compact high power 2-way loudspeaker system used in a variety of applications where high-quality sound reinforcement is required in an ultra compact light-weight enclosure. The enclosure design utilizes asymmetrical angles to maintain tight clearances to wall and ceilings while providing optimal coverage patterns making it ideal to blend into surroundings. This design is optimized for wall, stage lip and under balcony applications.
EVU Technical Manual Electro-Voice Model Number Notation The Electro-Voice Model Number notation indicates the loudspeaker series, woofer quantity, woofer diameter, quantity of band passes in the system, and following a forward slash, the coverage pattern. An example using the EVU-1062/95 is shown in Table 2. The EVU-1062/95 uses a single ICT series 6.5in. woofer in a two-way configuration and a 90° x 50° pattern. TABLE 2.

Introduction Parts List The EVU loudspeaker shipment includes the following: • • • • • • • • FIGURE 27.
EVU Technical Manual Tool List The tools required to prepare the EVU system for installation are as follows: 3/16in. flat blade screwdriver Phillips #2 screwdriver NOTE: 14 This screwdriver is also required to install the optional transformer kit or NL4 cover plate. For more information, see “Optional Accessories” on page 9.
CHAPTER 2 Installation Digital Signal Processing For full-range passive systems, the internal crossover/equalizer network sends low frequencies to the woofer and high frequencies to the compression-driver/waveguide combination. In addition, the network tailors the frequency response and levels of each individual driver so the overall frequency response of the loudspeaker is essentially flat over its design operating range.
EVU Technical Manual Preparing the EVU for Installation Rotation of the High-Frequency Waveguide Sub Assembly All high-frequency waveguide sub assemblies have their horizontal and vertical patterns molded on the front of the waveguide for easy identification of orientation. The high-frequency waveguide sub assembly can be rotated to change the high frequency pattern.
Installation Connecting the Loudspeaker to the Signal Wires To connect the signal wires to the connector on the back of the loudspeaker, do the following: NOTE: This procedure is not illustrated. Tools: 3/16in.flat blade screwdriver 1. Loosen the + and - screws. 2. Attach the signal wires to the appropriate + and - terminal positions on the connector. NOTE: Attach only one (1) signal wire per terminal. 3. Tighten the + and - screws until the signal wire is secure.
EVU Technical Manual EVU Rigging All EVU loudspeaker systems incorporate heavy-duty M8 threaded accessory attachment points inside each enclosure. These attachment points allow the user to install single systems in horizontal and vertical configurations. The universal U-Bracket allows for installation in horizontal or vertical configurations with the ability to position the loudspeaker at any angle up to 330° of total rotation with the transformer kit accessory.
Installation FIGURE 29. WARNING: Universal U-Bracket Assembly The Universal U-Bracket is designed to hold the weight of one (1) loudspeaker. Never attempt to mount multiple loudspeakers to a single u-bracket.
EVU Technical Manual To install the assembled U-Bracket to the enclosure, do the following: NOTE: All EVU systems are assembled in the following manner: Tools: #2 Phillips screwdriver 1. Remove two (2) M8 flat head screws (C) from each end of the loudspeaker enclosure (A). 2. Position the loudspeaker enclosure inside the universal u-bracket (B). 3. Place one (1) M8 rubber washer (D) between the enclosure’s screw hole and the universal u-bracket on each side of the enclosure.
Installation Mounting the Universal U-Bracket to the Wall The Universal U-Bracket is mounted to a wall using the holes provided in bottom rail. See Figure 31 for hole locations. WARNING: NOTE: FIGURE 31. Never under any circumstances mount the loudspeaker to a wall using wall anchors in drywall. Mounting to the structure is the responsibility of all others. For mounting to a wall, use two (2) 5/16in fasteners (recommended) or use two (2) 1/4in fasteners (minimum requirement) including two (2) washers.
EVU Technical Manual Optional Omnimount Bracket The Optional Omnimount Bracket, available from Omnimount, is used to facilitate mounting. The back panel of any of the EVU loudspeaker systems includes four (4) heavy-duty T-nut mounting points for an Omnimount style bracket. Four (4) M8 pan head Phillips screws are included in the EVU series hardware kit for mounting to an Omnimount bracket.
Installation To install the optional Omnimount bracket to the enclosure, do the following: NOTE: This procedure is not illustrated. Tools: #2 Phillips screwdriver. 1. Remove four (4) M8 flat head screws from the back of the loudspeaker enclosure. 2. Position the optional Omnimount bracket over the bolt holes on the back of the enclosure. 3. Apply thread locker (not included) to the four (4) M8 Pan head screws. 4.
EVU Technical Manual IMPORTANT: Eyebolts must be fully seated and oriented in the plane of pull as shown in Figure 34. Always use washers to distribute suspension loads. FIGURE 34.
CHAPTER 3 Working Load Limits and Safety Notices Working Load Limit and Safety-Factor Definitions Electro-Voice WLL The structural ratings for all of the EVU rigging components and complete loudspeaker systems are based on test results in which parts were stressed to failure (optional methods of rigging have not been tested by our facility). Manufacturers typically present the structural-strength ratings of mechanical components or systems as either the WLL or the ultimate-break strength.
EVU Technical Manual IMPORTANT: When an EVU loudspeaker system is installed where local regulations only require a safety factor of 5:1, Electro-Voice insists that the WLL of the EVU rigging never be exceeded and that an 8:1 safety factor be maintained for the EVU loudspeakers. The user is cautioned that some local regulations may require safety factors higher than 8:1.
