Xi-1082
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
Install™ is the ideal choice for small-to-medium array configurations and fixed installations of any size.
Inspired by the most demanded features of
EV's acclaimed X-Array™ touring systems,
the X-Array Install™ series incorporates a
potent combination of very high output, medium- to long-throw "cells," and Ring-Mode
Decoupling (RMD™).
RMD™
Ring-Mode Decoupling is the same advanced
technology built into the X-Array™ touring
series. RMD™ produces substantially 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 issues,
acoustical solutions address acoustical modes
found in all sound reinforcement systems.
The combination of each RMD™ technique
provides improved tonal character and fidelity at increasing drive levels. The result is
clear, even sound quality with vastly improved intelligibility.
Magnetics
Mid-bass and high-frequency drivers in
X-Array Install™ products use ferrite magnetics instead of the neodymium magnetics
used in X-Array™ touring systems. While
neodymium drivers provide unmatched output capabilities, the advanced RMD™ technology used in X-Array Install™ produces
world class sound reinforcement at very high
levels.
Applications
The Xi-1082 loudspeaker system is ideal for
any professional touring or installation application requiring accurate, high-level,
sound reinforcement. Because of the unique
performance capabilities featured in this system, the X-Array Install™ Xi-1082 offers
extremely wide-range music reproduction as
well as accurate vocal coverage and maximized intelligibility. It's single 8-inch woofer
avoids the mid-bane interference nulls of the
dual spaced woofers in "traditional" under
balcony systems.

power tests which push the performance
boundaries of the loudspeakers are also performed for an extra measure of reliability.
The Xi-1082 systems are rated per ANSI/
EIA RS-426-A Loudspeaker Power Rating,
Full Range Test, which uses a shaped-random-noise signal to simulate typical music
to test the mechanical and thermal capabilities of the loudspeakers. Specifically,
the Xi-1082 passes the ANSI/EIA

Suspending the Xi-1082
The Xi-1082 is fitted with several threaded
inserts and can be suspended as follows:
1. Two 3/8-16 threaded inserts are located
on each side of the enclosure to allow
the use of the Mb1082 mounting bracket.
The Mb1082 is a universal U-bracket de
signed to allow the suspension of the Xi1082 at any angle and orientation from

the wall or ceiling. Full instructions are
included with the Mb1082.
2. OmniMount Series 100 support system.
Four 5/16-18 threaded inserts are located
in the rear panel to allow use of the
OmniMount Series 100 support system.

WARNING: It is the responsibility of the
installer to ensure that the mounting surface has sufficient rigidity to support the
Xi-1082 Loudspeaker System
Xi-1082 and that the mounting bracket is
TM
correctly fitted to the surface and to the
Xi-1082. Suspending an object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regu-
X-Array Install
lations of rigging objects overhead. It is
the responsibility of the installer to ensure
the Xi-1082 is safely installed in accordance
with applicable regulations. If the Xi-1082
is suspended, Electro-V oice strongly recommends that the system be inspected at least
once a year . If any sign of weakness or damage is detected, remedial action should be
taken immediately.

Figure 1— Polar Response
The directional response of the system was measured in an anechoic environment at a distance of 6.1 m (22 feet) using 1/3-octave-filtered pink
noise with a full spherical measurement system. The polar response of the loudspeaker system at selected 1/3-octave frequencies is shown.
The selected frequencies are representative of the polar response of the system.

Figure 5— Distortion
Distortion for the system was measured on
axis in the farfield in an anechoic environment with an input signal that would result in
a 10% power rating (17.5 watts). A frequency
spectrum typical of close-miked rock music
was employed. The sound-pressure level was
normalized for an equivalent one-meter distance. Plots of second and third harmonic distortion are shown referenced to the fundamental.
