Electro-Voice Xi-1152/64 Instructions Manual

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

Sound-Reinforcement
System
• Ring-Mode Decoupling (RMD™)
• Substantially improved vocal range
performance
• New EVX-155 woofer with 3-dB additional
LF output, increased power handling/
lower distortion
• New DH6 compression driver
• New HF horn (60° x 40°) fully rotatable for
vertical or horizontal suspension
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.

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-
