Electro-Voice Xi-1152/94 Quick Start Manual

Xi-1152/94

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, 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.

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-1152/94 loudspeaker system is ideal
for any professional touring or installation
application requiring accurate, high-level

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.

Electrical Connection and System
Wiring

Electrical connections to the Xi-1152/94 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-1152/94 systems. The Neutrik

The Xi-1152/64 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. The Dx34 digital
electronic unit was used to provide the
necessary crossover filters and equaliza­tion during power testing. Specifically, the

Crossover, Equalization and Time-Delay
Controller

The Xi-1152/94 speaker system and variants
are 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-1152/94
speaker system can only be assured when
using the above referenced controllers.

All controllers used with the Xi-1152/94
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-1152/94.

HF: 125-250 watts continuous into 8 ohms

Xi-1152/94 speakers may be paralleled only

with other Xi-1152/94 speakers if the am-

plifier is capable of delivering full power at

the lower impedances. The use of amplifi-

ers 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-1152/94 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 appropri-

ate settings.

Flying the X-Array Install™ Systems

A manual entitled the X-Array Install™ Fly-

ing Manual is available from Electro-Voice,

and is included with each flying Xi loud-

speaker system. A brief introductory over-

®

NL4MPR is used for both connec-

Pin 1+: LF(+)
Pin 1-: LF(–)

Pin 2+: HF(+)
Pin 2-: HF(–)

view 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 L­track-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 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
NH32101-2S double-stud fitting, and 113 kg
(250 lb) when used with the New Haven
NH8192-2 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 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 updates notices.

Field Replacement

The Xi-1152/94 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. 815-3075
HF: Diaphragm kit; EV Part No. 84233-XX
