Electro-Voice X-Array Install Xi-2123/106 User manual

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 In-
stall™ is the ideal choice for small-to-me-
dium array configurations and fixed instal-
lations of any size.
Inspired by the most demanded features
of EV's acclaimed X-Array™ touring sys-
tems, the X-Array Install™ series incorpo-
rates a potent combination of very high
output, medium- to long-throw "cells," and
Ring-Mode Decoupling (RMD™). The Xi-
2123/106 is the first in a series of compact,
low- to medium-throw enclosures with op-
timized directivity for a wide range of ap-
plications.
Ring-Mode Decoupling (RMD™)
RMD™ (Ring-Mode Decoupling) is the
same advanced technology built into the
X-Array™ touring series. RMD™ pro-
duces substantially improved tonal char-
acter and fidelity whether operated at low
or extremely high sound pressure levels.
RMD™ attacks time domain "ringing
modes" at their sources. Mechanical solu-
tions resolve mechanical issues, and
acoustical solutions address acoustical
modes found in all sound reinforcement
systems. The combination of each RMD™
technique provides improved tonal char-
acter and fidelity at increasing drive lev-
els. The result is clear, even sound quality
with vastly improved intelligibility.
Xi-2123/106 and Three-Element Line Array
These triamp-ready, three-way systems in
a unique three-element-line-array configu-
ration are designed for use in reverberant
spaces. Dual spaced woofers flank and work
with the central mid-bass horn to form the
line array, extending vertical directivity con-
trol to below 160 Hz. Such wide-bandwidth
control and the low-Q (100° x 60°) pattern
provides superior direct-to-reflected SPL
ratios and improved system intelligibility,
and suppress feedback below arrays.
When optimum directivity control is re-
quired, the Xi-2123/106 with dual 12-inch
woofers should be used. The 10-inch mid-
bass driver features RMD™ and is coupled
to a rotatable 100° x 60° vertical horn.
The high-frequency system uses a DH6
large-format compression driver with a ro-
tatable 100° x 60° horn. It is mounted within
the upper woofer manifold to provide a
compact vertical size. For extended-bass/
subbass, the Xi-2123/106 may be used with
the Xi-1191 or Xi-2181 subwoofers.
Applications
The Xi-2123/106 is ideally suited for high-
level, high-fidelity applications. The sys-
tem is particularly suited where extended
vertical polar control is necessary. The
extended capabilities of the system, par-
ticularly the low-frequency capability, al-
low the system to be used in many appli-
cations without a subwoofer. For applica-
tions requiring very high low-frequency
sound pressure levels as well as very accu-
ratevocalreproduction,theXi-2123/106may
be coupled with the Electro-Voice Xi-
1191 or Xi-2181. The combined system
should be run with a conventional
subwoofer crosssover implementation
(sub crossover to Xi-2123/106 at 80 Hz).
Power-Handling Test
Electro-Voice components and systems are
manufactured to exacting standards to en-
sure reliability in continuous use in arduous
real-life conditions. Besides utilizing indus-
try-standard power tests, extreme in-house

power tests which push the performance
boundaries of the loudspeakers are also
performed for an extra measure of reliabil-
ity. The Xi-2123/106 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.
The DN8000 digital electronic unit was
used to provide the necessary crossover
filters and equalization during power test-
ing. Specifically, the Xi-2123/106 passes the
ANSI/EIA RS426-A power test with the
following test parameters:
Low-FrequencySection:
PE(MAX): 600 watts
Test Voltages: 47.0 volts rms
94.0 volts peak
RSR(1.15RE): 3.68 ohms
Mid-bass Section:
PE(MAX): 300 watts
Test Voltages: 45.5 volts rms
91 volts peak
RSR(1.15RE): 6.9 ohms
High-Frequency Section:
PE(MAX): 75 watts
Test Voltages: 30.1 volts rms
60.2 volts peak
RSR(1.15RE): 12.1 ohms
Biamplifying, Crossover, Equalization
And Time-Delay Controller
The Xi-2123/106 speaker system and vari-
ants are designed as an integrated pack-
age that utilizes the Merlin ISP-100, Klark
TeknikDN8000orElectro-VoiceDx34Adigi-
tal crossover system. Optimal performance
of the Xi-2123/106 speaker system can only
be assured when using the above control-
lers. The systems may be biamplified by
removing the input panel and switching a
6-pin molex connector. Separate presets
are available for the biamplified mode.
Electrical Connection And System
Wiring
Electrical connections to the Xi-2123/106
are made on the back of the enclosure via
an 8-pin connector. There are two connec-
tors on the input panel to allow paralleling
of other Xi-2123/106 systems. The Neutrik
Speakon® NL8MPR is used for both con-
nections. The pin assignments are as fol-
lows:
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 sys-
tem is shown in figure 7. The electrical im-
pedance is shown in Figure 6.
AmplifierRecommendations
Power amplifiers with the following rat-
ings are recommended for use with the
Xi-2123/106 speaker systems:
LF: 600 watts per channel into 8 ohms.
MB: 600 watts per channel into 8 ohms.
HF: 600 watts per channel into 8 ohms.
Xi-2123/106 speakers may be paralleled
only with other Xi-2123/106 speakers if the
amplifier is capable of delivering full power
at the lower impedances. The use of am-
plifiers with lower power ratings is accept-
able; 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 dy-
namic range and fidelity, but care must be
utilized for longer duration signals as me-
chanical 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 brief introductory
overview is included here. The X-Array In-
stall™ Flying Manual should be con-
sulted for complete structural specifications
and detailed information on safely sus-
pending and using the Xi systems.
The Xi systems incorporate a unique two-
pointflying system thatpermits a widerange
ofvertical angle adjustment, andoffersmaxi-
mumflexibility in arraydesign for bothtour-
ing sound and permanent installations. The
quick-release, aircraft-rated heavy-duty L-
track-type hardware design allows arrays of
loudspeakers to be assembled (and disas-
sembled) very quickly, and offers such flex-
ibility in the vertical angling of cabinets
that pull-up points are usually unneces-
sary. 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 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 fac-
tor) for the overall enclosure is 340 kg
(750 lb). (Consult the X-Array Install™
Flying Manual for specific structural rat-
ings 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 rig-
ging is the responsibility of others.
CAUTION: The Xi loudspeaker system
should be suspended overhead only in ac-
cordance with the procedures and limita-
tionsspecifiedin the X-ArrayInstall™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 hexkey
wrench. The drivers may be accessed as fol-
lows:
HF: First remove the grille, then remove
the nine screws securing the front flange
of the high-frequency horn. Lift the horn
and driver out of the wood assembly. In
the event of failure, the diaphragm assem-
bly can be replaced with the driver attached
to the horn.
MB: First remove the grille, then remove
the sixteen screws securing the front flange
of the midbass horn and lift the horn out.
Remove the four screws securing the phase

plug baffle and lift the baffle assembly out
of the enclosure. Remove the remaining
four screws securing the 10-inch midbass
and lift the driver out of the enclosure. In
the event of failure, the entire woofer must
be replaced.
LF: First remove the grille, then remove the
screws securing the hatch on the front of
the enclosure. In both the upper and lower
woofer hatches, four screws pass through
the midbass horn and must be removed.
The hatches and woofers may both be re-
moved without removing the midbass horn.
To remove the hatch under the high-fre-
quency horn, the HF horn must be removed
first. Remove the four screws securing the
12-inch woofer and lift the driver out of the
enclosure. In the event of failure, the en-
tire woofer must be replaced.

Figure 1—Polar Response
The directional response of the system was measured in an anechoic environment at a distance of 6.1 m (22.0 feet) using 1/3-octave-filtered pink noise
with a full spherical measurement system. The Merlin ISP-100 digital electronic unit was used to provide the necessary three-element-line-array
crossover filters, equalization and time delay. 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.The horizontal polar is from the perspective of looking down on the top of the
loudspeaker, where 270° is to the left and 90° is to the right. The vertical polar is from the perspective of looking at the side of the loudspeaker, where
90° is to the top and 270° is to the bottom. 0° is directly on axis of the loudspeaker both horizontally and vertically.

Figure 4—Directivity
The directivity index, Di, and directivity fac-
tor, Rθ , of the system were measured with a
full spherical measurement system as de-
scribed for the Polar Response.
Figure 3—Beamwidth
The beamwidth of the system, (i.e., the in-
cluded horizontal and vertical coverage
angles at the -6-dB points) was measured
with a full spherical measurement system as
described in Polar Response.
Figure 5—Distortion
Distortion for the system was measured
on axis in the farfield in an anechoic envi-
ronment with an input signal that would
result in a sound-pressure level of 115 dB
at one meter. The ISP-100 digital electronic
unit was used to provide the necessary
three-element-line-array crossover filters,
equalization and time delay. A frequency
spectrum typical of close-miked rock mu-
sic was employed. The sound-pressure
level was normalized for an equivalent one-
meter distance. Plots of second and third
harmonic distortion are shown referenced
to the fundamental.
Figure 2—Frequency Response
The frequency response of the system was
measured on axis in the farfield in an
anechoic environment using a swept sine-
wave signal. The ISP-100 digital electronic
unit was used to provide the necessary
three-element-line-array crossover filters,
equalization and time delay. One-half watt
of power (2.83 volts rms at 1000 Hz) was
applied to the midband of the midbass sec-
tion. The sound-pressure level was nor-
malized for an equivalent one-meter dis-
tance.
