EV CINEMA SYSTEMS

CINEMA. For a medium generally thought of as being visual,
the quality of a theater's sound system often determines the
"cinema experience" for the paying customer. For years
Electro-Voice

®

has supplied loudspeaker systems, amplifiers
and controllers to the cinema industry which have met or
exceeded the standards set by THX or Dolby Laboratories.
Every summer, with release of the latest blockbuster action
film, new benchmarks for acoustic performance are set — and
Electro-V oice continues to meet these demands with the most
innovative products in the industry. Products that meet the
demands of digital sound.

At Electro-Voice we offer the engineering knowledge and
expertise to design and manufacture products "from the
ground up". Electro-Voice loudspeakers, amplifiers and
controllers are conceived from the component level and
integrated into high-performance audio systems, consisting of
screen channels, surround and subwoofer systems. We are
committed to developing new technologies and achieving new
levels of performance for complete cinema speaker systems.

EV Asymmetric Directed
CoverageTechnology
in VARIPLEX™ II

Electro-Voice pioneered Ring Mode Decoupling®(RMD®)
as a result of experience gained through years of
high-level system design. The goal of that basic research is
to bring those new technologies into all aspects of the
sound reinforcement industry, including EV’s commitment
to Cinema.

All loudspeaker components display unwanted vibrational
modes — or resonances — that produce both frequency
and time-domain distortions. A time-domain distortion is
most often described by loudspeaker users as a “ringing”
in the system. This ringing is usually most audible through
the vocal fundamental range, and users commonly
attempt to “cure” the ringing mode through equalization.
Unfortunately such attempts remove not only the time­domain distortion, or ringing, but also parts of the musical
signal as well. The net result is that musical information
and intelligibility is lost. RMD

®

is a series of techniques
developed by Electro-Voice engineers to deal with the
time-domain distortion at its source. The basic problem is
mechanical in nature. As a result, the only really effective
solution is also mechanical. When acoustic resonances are
encountered, the only effective solution is an acoustic
remedy. The same applies to electrical resonances:
The solution must be electrical.

RMD

®

treatment produces an acoustic signal that is less
affected by mechanical and acoustical ringing modes. The
result is a level of fidelity — particularly through the critical
vocal range — that is more coherent. Another benefit of
RMD

®

technology is a much higher degree of level

independence. RMD

®

greatly minimizes the changes in
system voicing that occur with level changes. Systems
with RMD

®

, therefore, display a high degree of level­independent fidelity and a very audible improvement in
vocal clarity as well.

SPEAKER TECHNOLOGIES

Electro-Voice´s unique Asymmetric Directed Coverage
technology provides an effectively rectangular coverage
pattern. It provides advantages for most applications in

traditional and stadium seating
rooms. The unique throat and flare
structure of the Waveguide delivers a
6-10 dB signal increase to the rear of
the room. The resulting even front­to-back SPL eliminates ear-strain at
the back of the sitting area and
painful levels at the front. Aimed
horizontally, the ADC Waveguide
delivers sound only to the audience
area, providing uniform direct-field

SPL and significantly reducing the
amount of sound reflections off the ceiling. This provides an
increase in mid- to high-frequency intelligibility of 6 dB in
most applications. The ADC Waveguide also provides lower
distortion and very smooth uniform frequency response.

EV Theater Guide

EV developed an intuitive software tool to assist designing the best system for a theater . It guides the selection
of the correct screen channel speaker, subwoofer, surround speaker, and power amplifier. Simply enter the
dimensions of the room and screen, and the program will suggest the model, location, and aiming information
of the screen channel speakers, surround speakers, and subwoofers. It also provides amplifier information.
EV’s Theater Speaker Guide (TSG) is available at no cost on www.electrovoice.com.
