Xi-1152/64
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-1152/64 loudspeaker system is ideal
for any professional touring or installation
application requiring accurate, high-level
X-Array Install
™
Two-Way, Full-Range,
Sound-Reinforcement
System
• Ring-Mode Decoupling (RMD™)
• Substantially improved vocal range
performance
• New EVX-155 woofer with 3-dB additional
LF output, increased power handling/
lower distortion
• New DH6 compression driver
• New HF horn (60° x 40°) fully rotatable for
vertical or horizontal suspension
sound reinforcement. Because of the unique
performance capabilities featured in this system, the Xi-1152/64 offers extremely widerange music reproduction as well as accurate vocal coverage and maximized intelligibility.
The Xi-1152/64 is recommended for applications requiring full bandwidth down to
50 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 subwoofer 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-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 capabili-
X- Array Install™ Xi-1152/64 Loudspeaker System
ties of the loudspeakers. The Dx34 digital
electronic unit was used to provide the
necessary crossover filters and equalization during power testing. Specifically, the
Xi- 1152/64 passes the ANSI/EIA RS-426A power test with the follwing test parameters:
Low-Frequency Section:

Crossover, Equalization and Time-Delay
Controller
X-Array Install™-1152/64 Loudspeaker System
The Xi-1152/64 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-T eknik DN8000.
Optimal performance of the Xi-1152/64
speaker system can only be assured when
using the above referenced controllers.
All controllers used with the Xi-1152/64 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-1152/64.
Electrical Connection and System
Wiring
Electrical connections to the Xi-1152/64 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-1152/64 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 im-
2
pedance is shown in Figure 6.
Amplifier Requirements
Power amplfiers with the following ratings
are recommended for use with the
Xi-1152/64 speaker systems:
LF: 600-1,200 watts continuous into 8 ohms
HF: 125-250 watts continuous into 8 ohms
Xi-1152/64 speakers may be paralleled only
with other Xi-1152/64 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 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-1152/64 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 offers 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 X-Array Install™ loudspeaker system should be suspended overhead only in accordance with the procedures and limitations specified in the
X-Array Install™ Flying Manual and
manual update notices.
Field Replacement
The Xi-1152/64 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
