CHAPTER 1

Intr oduction

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 1.3in titanium compression driver coupled to a Constant Directivity*

waveguide. The EVU woofers are developed using FEA (Finite Element An alysis) optimization to provide the highest
sensitivity while achieving the highest level of speech intelligibility.

1

90 x 50 rotatable

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*
Omnimount Inc. An available 60W transformer kit is easily mounted over the input pa nel for use in distributed systems. An
NL-4 cover plate accessory is available to simplify use as a portable system. All of these features give you the flexibility to
address a large range of venues, quickly and precisely supporting customer requirements.

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 add ition, 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.

Once the ECU system

Once the EVU systems is installed in its venue, a DSP (Digital Signal Processor) is used to adjust the in-room frequency
response, based on the specifics of the venue. In addition, the DSP should be used to provide the high-pass filters
recommended to protect the EVU system against overdrive at frequencies below their operating range, failure to do so could
damage the low-frequency drivers if fed high-level signals below the system’s operating range. The recommended high-pass
filter frequencies for infrasonic protection of EVU system is shown in Table 3.

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.

NOTE: The high-frequency waveguide sub assembly is installed at the factory with the 90° wave pattern oriented along

the long axis of the enclosure for all models.

FIGURE 28. High-Frequency Waveguide Sub Assembly Orientation

To change the high-frequency waveguide sub assembly’s orientation, do the following:

Tools: #2 Phillips screwdriver

1. Remove the eight (8) screws (A) from the top and bottom of the grille.

NOTE: The grilles on the single woofer models, EVU-1062 and EVU-1082, use six (6) screws.

2. Remove the grille (B).

3. Remove the eight (8) screws (C) holding the high-frequency waveguide sub assembly.

4. Rotate the high-frequency waveguide sub assembly 90° (D) until the desired pattern (90° or 50°) marking is located

along the long axis of the enclosure.

5. Reinstall the high-frequency waveguide sub assembly (D) with eight (8) screws (C).

6. Reattach the grille (B) to the front of the loudspeaker (E).

16

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.

Troubleshooting

Problem Possible Cause Action

No Sound Amplifier Connect a known working test loudspeaker to the amplifier

outputs. If there is no sound, check that all the electronics are on,
the signal routing is correct, the source is active, the volume is
turned up, and so on. Correct/repair/replace as necessary . If there
is sound, the problem is in the wiring.

Wiring Verify you have connected the correct wire pairs to the amplifier.

Play audio at a low level through the amplifier (for example,
from a CD player or tuner). Connect the test loudspeaker in
parallel with the malfunctioning line. If the sound level has gone
or is very weak, the line has a short in it (possibly a severe scrape,
pinch, or staple puncture). If the sound level is normal, the wire is
open (possibly a cut wire or a missed connection). Observe
proper polarity and use the test loudspeaker to move down the
line and test each connection/junction until you find the problem
and correct it.

Intermittent output such
as crackling or distortion

Constant noise such as
buzzing, hissing or,
humming

If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or Electro-Voice distributor.
See “Contact Information” on page 27.

Faulty Connection Check all connections at amplifier and speakers to ensure they

are all clean and tight. If the problem persists, it may be in the
amplifier or wiring. See Problem 1 above.

Defective amplifiers or
other electronic device

Poor system grounding
or ground loop

If the noise is present but no audio is playing, the likely cause is
the signal chain in the electronics. Evaluate each component as
necessary to isolate the problem.

Check and correct the system grounding, as required.

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.
Electro-Voice chooses to present the structural-load ratings of the EVU loudspeaker systems as the WLL. The WLL rating
represents the maximum load that can be applied to a mechanical component or system.

WARNING: The user should never apply loads that exceed the WLL of any of the rigging components or complete

loudspeaker systems described in the manual.

Factor of Safety

The WLL for the EVU rigging components and complete loudspeaker systems described in this manual are based on a
minimum 8:1 safety factor. The safety factor is defined as the ratio of the ultimate break strength divided by the WLL, where
the ultimate break strength represents the force at which a part fails structurally.

For example, if a part has a WLL of 35lb. (15.8kg.), it would not structurally fail until a force of at least 280lb. (127kg.) was
applied, based on an 8:1 safety factor.

WARNING: The user should never apply a load to that part that exceeds the value listed in this manual for these products.

The safety factor provides a margin of safety above the WLL to accommodate normal dynamic loading and
normal wear.

WARNING: For WLL and Safety Factors, the WLL defined by the manufacturer of any rigging component should never

be exceeded. Electro-Voice bases the WLL of its EVU products on a minimum of an 8:1 safety factor. Other
manufacturers of rigging components may base their WLL on safety factors other than 8:1. For example, 5:1
safety factors are fairly common among rigging manufacturers because many regulatory agencies call for a
minimum safety factor of 5:1.

25

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. In that circumstance, Electro­Voice insists the user maintain the higher safety factor as required by the local regulations throughout the entire EVU
installation. It is the responsibility of all others to make sure any EVU installation meets all applicable local, state or federal
safety regulations.
