CHAPTER 1
Introduction
WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a
thorough knowledge of the techniques and regulations of suspending objects overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into account all current national, federal, state, and local laws and regulations. It is the responsibility of the installer to ensure all loudspeakers are safely installed in accordance with all such requirements. When loudspeakers are suspended, Electro-Voice strongly recommends the system be inspected at least once per year or as laws and regulations require. If any sign of weakness or damage is detected, remedial action should be taken immediately. The user is responsible for making sure the wall, ceiling or structure is capable of supporting all objects suspended overhead. any hardware used to suspend a loudspeaker not associated with Electro-Voice is the responsibility of others.
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. The EVU series incorporates the ICT (Install Compact Transducer), a high-output 1.3-inch titanium compression driver coupled to a Constant Directivity* 90 x 50 rotatable waveguide. The EVU woofers are developed using FEA (Finite Element Analysis) optimization to provide the highest sensitivity while achieving the highest level of speech intelligibility.
The crossover designs uses 18dBper octave slopes with equalization for very smooth response in the vocal range, linear off-axis response and a protection circuit for long term reliability. The EVU line is constructed of multi-ply hardwood plywood enclosure with six (6) integral M8 suspension points to support a wide variety of mounting positions.
The EVU system is finished in textured paint available in either white or black. Each EVU system includes a universal U-Bracket to facilitate mounting. The U-Bracket provides for a 330° unobstructed, translation of the loudspeaker. Additional mounting points are located on the back of the enclosure for use with an Omnimount* type bracket, available from Omnimount Inc. An available 60W transformer kit is easily mounted over the input panel for use in distributed systems.

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 6.5 inch woofer in a two-way configuration and a 90° x 50° pattern.
