X-Array™: Ring-Mode Decoupling (RMD™), for
the best vocals you have ever heard. X-Array™ marks the family of Electro-Voice loudspeaker systems with Ring-Mode Decoupling. RMD provides spectacularly clear vocals and smooth midrange at all output levels. The X-Series™ employs neodymium magnetics and a rigging system designed and especially appropriate for large, world-class touring arrays.
X-Array™ Xi-Series™: High intelligibility in rever-
berant spaces through extended-frequency
directivity control. The Xi-Series™ described in
this brochure adds models particularly appropriate for high-performance fixed installations. Included are twoand three-element line-array configurations, which increase intelligibility and clarity in reverberant spaces through extended-frequency directivity control.
Suspension hardware and magnetics are optimized for permanent installation or portable applications of small-to-medium size. The Xi-Series™ also includes two-way systems in a range of sizes and coverage patterns to augment the performance of the main three-

X-Array™ Xi-Series™ includes special features that set the systems apart.
Twoand three-element line arrays: Extendedfrequency directivity control
Using Merlin® signal processing, “dipole”
and “tripole” configuration of the Xi-1123, Xi-2123, Xi-1153 and Xi-2153 provides vertical coverageangle control to as low as
125 Hz. More of the important vocal range is aimed at the absorptive audience instead of the reflective room surfaces. This helps increase intelligibility in reverberant spaces. Reduced output below the systems suppresses feedback from microphones under the loudspeakers.
Ring-Mode Decoupling (RMD™): Breathtaking vocal quality
Many acoustic
and mechanical delayed reso-
nances color the sound of typical loudspeakers. EV
engineers have systematically exposed these resonances and suppressed them one by one. We call this process Ring-Mode Decoupling, or RMD™. The resonances may not be measurable by conventional means, and are typically many dB below the desired signal. But the human ear/brain combination is extremely sensitive to such signals. RMD™ gives a quality of sound and degree of clarity that audiences find breathtaking.
Ring-Mode Decoupling (RMD™): Level-independent fidelity
In typical speaker systems, as the
overall sound pressure level is increased — such as during a musical performance — the delayed resonances increase proportionally more than the primary signal. This sends the sound operator to the equalizers in an attempt to "fix" the sound. It is an ill-fated attempt since changing the response of the system cannot eliminate the unpleasant resonances. RMD™ suppresses acoustic and mechanical resonances at their source.
DH6 large-format driver: Exceptional HF detail
at all SPL’s
All three-way and virtually every
two-way system in the series use a new largeformat compression driver with RMD™. The titanium diaphragm of the DH6 has
increased internal strength and damping for unprecedented HF clarity and resistance to mechanical fatigue at very high sound levels. The reduced diaphragm-to-phase-plug spacing applies acoustic damping and maintains output in the 10– to 20-kHz range.
Rotatable HF horns: Coverage flexibility
Nearly every Xi-Series™ system
has a rotatable HF horn. It is designed so the intended coverage angle can be maintained for vertical and horizontal box orientations. (The 100° x 60° Xi-2123 and Xi-1123 also have rotatable mid-bass horns.)
Rigging: L-tracks with 8:1 safety factor
Xi-Series™ systems
(with the excep-
tion of the ultracompact Xi-1082 underbalcony) have dual L-tracks top and bottom for two-point suspension and aiming. The L-track extrusions are tied together by internal aluminum bars which take the load entirely away from the 13-ply birch enclosures. As a result, a safe and conservative suspension system is formed, one that can be used with confidence. Even in the largest
vertical arrays recommended, an 8:1 safety factor is maintained. The L-tracks accept a number of singleand double-stud
fittings (see engineering data sheets and Xi-Series™ Flying Manual*).
*The user is responsible for determining the loads on all mechanical components throughout the loudspeaker array and for ensuring that the working-load limits and resulting safety factors are not exceeded.

way systems – for down fill, far throw, delay rings, under balcony and low-frequency enhancement.
Many of the two-way systems also provide superb performance on their own when room acoustics and geometry are appropriate.
When performance demands are high, Xi-Series™, in combination with Merlin® signal processing, will find ideal application in performing arts centers, theaters, auditoriums, houses of worship and regional touring.

Carrying handles on each side of all Xi-Series™ enclosures
Specially designed
multigrip handles
are extremely comfortable and can be gripped from any angle, making lifting much easier. The large sys-
tems feature four handles per side, and the compact two-way systems have two handles
per side. (The
ultracompact Xi-1082 underbalcony system has no handles.)
Power: Unrivaled fidelity at high outputs
Electro-Voice Precision Series™
power amplifiers perfectly complement Xi-Series™ and are on tour with the Rolling Stones and their X-Array™ X-Series™ system. Precision Series™ amplifiers exhibit very high peak output for uncompromised fidelity at
high sound levels (140 volts peak — nearly 2,500 watts into 8 ohms — for the P3000; 110 volts peak — over 1,500 watts
— for the P2000). Dual power supplies allow driving subs and midor high-channels from the same amplifier, without signal degradation.

line
arrays
The “tripole” configuration of the Xi-2153/64 and Xi-2123/106 allows output from the mid-bass horn to join that of the spaced, dual low-frequency sources and provide exceptional vocal clarity in rever-berant spaces and resistance to feedback beneath the loudspeaker. This is accomplished
by extending a precisely controlled radiation pattern to unusually low frequencies.
