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-me- dium 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, mediumto 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, 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-1122/85 loudspeaker system is ideal for any professional touring or installation application requiring accurate, high-level
sound reinforcement. Because of the unique performance capabilities featured in this system, the X-Array Install™ Xi-1122/85 offers extremely wide-range music reproduction as well as accurate vocal coverage and maximized intelligibility.
The Xi-1122/85 and associated controller combinations are recommended for applications requiring full bandwidth down to 60 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 woofer 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 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 reliability. The Xi-1122/85 systems are rated per ANSI/ EIA RS-426-A Loudspeaker Power Rating, Full Range Test, which uses a shaped-ran-

dom-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 Xi-1122/85 passes the ANSI/EIA RS-426-A power test with the follwing test parameters:
Low-Frequency Section:

Crossover, Equalization and Time-Delay
Controller
The Xi-1122/85 speaker system (and variants) is 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-1122/85 speaker system can only be assured when using the above-referenced controllers. All controllers used with the Xi-1122/85 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-1122/85.
Electrical Connection and System
Wiring
Electrical connections to the Xi-1122/85 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-1122/85 systems. The Neutrik Speakon® NL4MPR is used for both connections. 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 impedance is shown in Figure 6.
Amplifier Requirements
Power amplfiers with the following ratings are recommended for use with the Xi-1122/85 speaker systems:
LF: 300-600 watts continuous into 8 ohms. HF: 125-250 watts continuous into 8 ohms.
Xi-1122/85 speakers may be paralleled only with other Xi-1122/85 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-1122/85 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 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 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 NH32101-2 double-stud fitting, and 113 kg (250 lb) when used with the New Haven NH8192-2S or Ancra 42546-10 single-stud fittings with locking pins. The working-load (for an 8:1 safety factor) limit 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™ Flying Manual and manual update notices.
Field Replacement
The Xi-1122/85 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. 812-3073 HF: Diaphragm kit: EV Part No. 84233-XX
