Description

Introducing a family of advanced sound

reinforcement products for everyone who

desires the sound quality of Electro-Voice's

X-Array™ touring systems. X-Array In-

stall™ is the ideal choice for small-to-me-

dium array configurations and fixed instal-

lations of any size.

Inspired by the most demanded features

of EV's acclaimed X-Array™ touring sys-

tems, the X-Array Install™ series incorpo-

rates a potent combination of very high

output, medium- to long-throw "cells," and

Ring-Mode Decoupling (RMD™).

RMD™

Ring-Mode Decoupling is the same ad-

vanced technology built into the X-Array™

touring series. RMD™ produces substan-

tially improved tonal character and fidelity

whether operated at low or extremely high

sound pressure levels. RMD™ attacks time

domain "ringing modes" at their sources.

Mechanical solutions resolve mechanical is-

sues, and acoustical solutions address acous-

tical modes found in all sound reinforcement

systems. The combination of each RMD™

technique provides improved tonal charac-

ter and fidelity at increasing drive levels. The

result is clear, even sound quality with vastly

improved intelligibility.

DH6 Large-Format Driver

All multiway systems in the series are

equipped with EV's newly developed DH6

large-format compression driver. The DH6

compression driver incorporates many

RMD™ techniques, including a new tita-

nium diaphragm with increased internal me-

chanical damping that provides clear, intel-

ligible upper vocal performance. The phase

plug placed close to the diaphragm improves

acoustic damping and boosts output in the

10-to 20-kHz range.

Magnetics

Mid-bass and high-frequency drivers in

X-Array Install™ products use ferrite mag-

netics instead of the neodymium magnetics

used in X-Array™ touring systems. While

neodymium drivers provide unmatched out-

put capabilities, the advanced RMD™ tech-

nology used in X-Array Install™ produces

world class sound reinforcement at very high

levels.

Applications

The Xi-1152/64 loudspeaker system is ideal

for any professional touring or installation

application requiring accurate, high-level

Power-Handling Test

Electro-Voice components and systems are

manufactured to exacting standards to en-

sure reliability in continuous use in arduous

real-life conditions.  Besides utilizing indus-

try-standard power tests, extreme in-house

power tests which push the performance

boundaries of the loudspeakers are also

performed for an extra measure of reliability.

The Xi-1152/64 systems are rated per ANSI/

EIA RS-426-A Loudspeaker Power Rating,

Full Range Test, which uses a shaped-ran-

dom-noise signal to simulate typical music

to test the mechanical and thermal capabili-

sound reinforcement.  Because of the unique

performance capabilities featured in this sys-

tem, the Xi-1152/64 offers extremely wide-

range music reproduction as well as accu-

rate vocal coverage and maximized intelli-

gibility.

The Xi-1152/64 is recommended for appli-

cations requiring full bandwidth down to

50 Hz.  Where very high levels of deep bass

are required, maximum performance may be

achieved with the addition of the Xi-1191

(single 18-inch subwoofer). This subwoofer

system features the EVX-180B 18-inch sub-

woofer and is designed to be used with as-

sociated processors.
