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™

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, and 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.

Xi-1153/64 and Two-Element Line Array

These triamp-ready, three-way systems in a
unique two-element-line-array configuration
are designed for use in reverberant spaces.
One woofer flanks and works with the mid­bass horn to form the line array, extending
vertical directivity control to below 200 Hz.
Such wide-bandwidth control and the me­dium-Q (60° x 40°) pattern provide superior
direct-to-reflected SPL ratios and improved
system intelligibility, and suppress feedback
below arrays.

When optimum directivity control is re­quired, the Xi-1153/64 with a single 15-inch
woofer (EVX-155), should be used. The
12-inch mid-bass driver features RMD™
coupled with a 60° x 40° vertical horn.

The high-frequency system uses a DH6 large­format compression driver with a rotatable
60° x 40° horn. It is coaxially mounted, asym­metrically positioned and fully "shrouded" to
preserve mid-bass wave-front detail. For
extended-bass/subbass, the Xi-1153/64 may
be used with the Xi-1191 subwoofer.

Applications

The Xi-1153/64 is ideally suited for high­level, high-fidelity applications. The ex­tended capabilities, of the system, particu­larly the low-frequency capability and verti­cal polar control allow the system to be used
very successfully without the need of a sub­woofer. For application of low-frequency
sound pressure levels coupled with very ac­curate vocal reproduction, the Xi-1153/64 may
be coupled with the Electro-Voice Xi-1191
subwoofer.

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
bounadries of the loudspeakers are also per­formed for an extra measure of reliability.
The Xi-1153/64 systems are rated per ANSI/
EIA RS426-A 1980 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.

Crossover, Equalization And Time­Delay Controller

The Xi-1153/64 speaker system and variants
are designed as an integrated package that
utilizes the Merlin ISP100, Klark Teknik
DN8000 or Electro-Voice Dx34A digital
crossover system. Optimal performance of
the Xi-1153/64 speaker system can only be
assured when using the above controllers.
For the three-way, non-overlap crossover
configuration, either the merlin ISP-100,
DN8000 or Dx34A may be used. For the
two-element-line-array configuration, how­ever, only the Merlin ISP-100 may be used.

Electrical Connection And System
Wiring

Electrical connections to the Xi-1153/64 are
made on the back of the enclosure via a
8-pin connector. There are two connectors
on the input panel to allow paralleling of
other Xi-1153/64 systems. The Neutrik
Speakon

®

NL8MPR is used for both connec-

tions. The pin assignments are as follows:

HF: Pin 4 In / Pins 4 Out
MB: Pin 3 In / Pins 3 Out

LF: Pin 1 In / Pins 2 Out

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

Amplifier Recommendations

Power amplfiers with the following rat­ings are recommended for use with the
Xi-1153/64 speaker systems:

LF: 600-800 watts continous into 8 ohms.
MB: 300-600 watts continous into 8 ohms.
HF: 125-250 watts continous into 8 ohms.
Xi-1153/64 speakers may be paralleled only

with other Xi-1153/64 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 to 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 is possible in the system.

Flying the Xi 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 breif 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 loudspeaker
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 loud-

speaker 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) at any angle when used with the New
Haven NH8192-2S or Ancra 42546-10
single-stud fittings with locking pins. The
working-load limit (for an 8:1 safety fac­tor) for the overall enclosure is 453 kg
(1,000 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.
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 updates notices.

Field Replacment

Normal service for the Xi requires only a #2
Phillips screwdriver and a 3/16-inch hex-key
wrench. The drivers may be accessed as fol­lows:

HF: First remove the grille, the remove the
screws securing the front flange of the high­frequency horn. Peel the hook and loop
fastner strips from the four corners of the
foam shroud and remove the four sides of
the shroud. Lift the horn and driver out of
the wood assembly. In the event of failure,
the diaphragm assembly can be replaced with
the driver attached to the horn.

MB: Remove the screws securing the hatch
on the back of the enclosure and lift the hatch
out. Remove the screws securing the 12-inch
woofer and lift the driver out of the enclo­sure. In the event of failure, the entire woofer
must be replaced.

LF: First remove the grille, the remove the
screws securing the hatch on the front of the
enclosure. Remove the screws securing the
15-inch woofer and lift the driver out of the

enclosure. In the event of failure, the entire
woofer must be replaced.

The following replacement parts are avail­able from Electro-Voice Service in Bucha­nan, Michigan:
