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 and that the mounting bracket is

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.
