Electro-Voice Xi-1122-85 User Manual

Xi-1122/85

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.

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 tita­nium diaphragm with increased internal me­chanical damping that provides clear, intel­ligible 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 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-1122/85 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-1122/85 of­fers extremely wide-range music reproduc­tion as well as accurate vocal coverage and
maximized intelligibility.
The Xi-1122/85 and associated controller
combinations are recommended for applica­tions requiring full bandwidth down to
60 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
woofer and is designed to be used with as­sociated processors.

Power Handling Test

Electro-Voice components and systems are
manufactured to exacting standards to en­sure reliability in continuous use in arduous
real-life conditions. Besides utilizing indus­try-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-1122/85 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 capabili­ties of the loudspeakers. The Dx34 digital
electronic unit was used to provide the
necessary crossover filters and equaliza­tion during power testing. Specifically,
the Xi-1122/85 passes the ANSI/EIA
RS-426-A power test with the follwing test

Controller

The Xi-1122/85 speaker system (and vari­ants) is designed as an integrated package
that utilizes any of the following controllers;
Merlin ISP100, Electro-Voice Dx34 digital
crossover system or Klark Teknik DN8000.
Optimal performance of the Xi-1122/85
speaker system can only be assured when
using the above-referenced controllers. All
controllers used with the Xi-1122/85 feature
a 1,480-Hz crossover frequency utilizing
24-dB-per-octave Linkwitz-Riley filters. All
contain fixed time-delay and equalization for
optimum performance of the Xi-1122/85.

Electrical Connection and System
Wiring

Electrical connections to the Xi-1122/85 are
made on the back of the enclosure via a
4-pin conncector. There are two connectors
on the input panel to allow paralleling of
other Xi-1122/85 systems. The Neutrik
Speakon

®

NL4MPR is used for both connec-

tions. The pin assignments are as follows:

Pin 1+: LF(+)
Pin 1-: LF(–)
Pin 2+: HF(+)
Pin 2-: HF(–)

The wiring diagram of the loudspeaker sys­tem is shown in Figure 7. The electrical im­pedance is shown in Figure 6.

Amplifier Requirements

Power amplfiers with the following ratings
are recommended for use with the
Xi-1122/85 speaker systems:

LF: 300-600 watts continuous into 8 ohms.

HF: 125-250 watts continuous into 8 ohms.
Xi-1122/85 speakers may be paralleled only
with other Xi-1122/85 speakers if the am­plifier is capable of delivering full power at
the lower impedances. The use of amplifi­ers with lower power ratings is acceptable;
however, the full-power capabilities of the
Xi speakers will not be realized. The use of
amplifiers with significantly higher power
ratings will generate maximum dynamic
range and fidelity, but care must be utilized
for longer duration signals as mechanical and
thermal damage are possible in the system.
Under certain circumstances, higher rated
amplifiers are acceptable. It is acceptable to
drive the Xi-1122/85 speakers with a stereo
power amp utilizing one channel to drive the
low frequencies and the other channel to
drive the high frequencies. See owner's
manuals on various controllers for appropri­ate settings.

Flying The X-Array Install™ Systems

A manual entitled the X-Array Install™ Fly­ing Manual is available from Electro-Voice,

and is included with each flying Xi loud­speaker system. A brief introductory over­view is included here. The X-Array Install™
Flying Manual should be consulted for com­plete structural specifications and detailed in­formation on safely suspending and using the
Xi systems.
The Xi systems incorporate a unique, two­point flying system that permits a wide range
of vertical angle adjustment, and offers maxi­mum flexibility in array design for both tour­ing sound and permanent installations. The
quick-release, aircraft-rated, heavy-duty,
L-track-type hardware design allows arrays
of loudspeakers to be assembled (and disas­sembled) very quickly, and of fers such flex­ibility in the vertical angling of cabinets that
pull-up points are usually unnecessary.
Furthermore, all of the flying Xi loud-

speaker models include the same rigging
hardware, allowing different models to be
mixed as necessary throughout an array.
The working-load limit (for an 8:1 safety
factor) for each rigging point on the Xi loud­speaker enclosure is 227 kg (500 lb) for a 0°
pull angle and 170 kg (375 lb) for a 90° pull
angle when used with the New Haven
NH32101-2 double-stud fitting, and 113 kg
(250 lb) when used with the New Haven
NH8192-2S or Ancra 42546-10 single-stud
fittings with locking pins. The working-load
(for an 8:1 safety factor) limit for the overall
enclosure is 340 kg (750 lb). (Consult the
X-Array Install™ Flying Manual for specific
structural ratings and limitations.) The en­closures may be oriented with the rigging
track on the sides of the enclosure, or on the
top and bottom, and may be daisy-chained
together as long as the safety factor is 8:1 or
greater, and local regulations are met. For
fire safety and additional structural strength
in both flying orientations, top-to-bottom and
side-to-side metal straps link the rigging
track inside the enclosure. Electro-Voice
offers a line of flying-hardware accessories
for use with the Xi loudspeaker systems.
All associated rigging is the responsibility
of others.

CAUTION: The Xi loudspeaker system
should be suspended overhead only in ac­cordance with the procedures and limita­tions specified in the X-Array Install™ Fly-
ing Manual and manual update notices.

Field Replacement

The Xi-1122/85 was designed for expedient
field service. Removing the woofer bolts
allows the woofer to be easily removed.
Removing the horn-mounting screws allows
access to the compression driver, both
through the horn and woofer baffle cutouts.
A woofer failure will require replacement of
the entire driver. In the case of a compres­sion driver failure, a diaphragm assembly
replacement kit with instructions is available.
If desired, the complete driver may be
returned for service.
The following replacement parts are avail­able from Electro-Voice Service in
Buchanan, Michigan:
LF: Complete woofer: EV Part No. 812-3073
HF: Diaphragm kit: EV Part No. 84233-XX
