Xi-1152/94 X-Array Install
Two-Way, Full-Range, Sound-Reinforcement System
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-levelsound 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.

Used Electro-Voice
Electro-Voice (commonly referred to as EV) is an American manufacturer of audio equipment, including microphones, amplifiers, and loudspeakers, focused on pro audio applications such as sound reinforcement.
As a subdivision of Telex Communications Inc. since February 1998, Electro-Voice markets products for use by consumers as well as small or large concert venues, broadcasting, houses of worship, and in retail situations.The company merged with Telex Communications in 1998.
Prior to the merger, EV was owned by Mark IV Industries, Inc. through its subsidiary, Gulton Industries, Inc., and had manufacturing plants in Buchanan, Michigan, Newport, Tennessee, Sevierville, Tennessee and Gananoque, Ontario. Electro-Voice's headquarters were in Buchanan, Michigan until the merger with Telex Communications.
In June 2006, EV, along with all of Telex Communications, became part of Bosch Security Systems division.Today EV manufactures widely used broadcast microphones as well as loudspeakers and various other professional audio equipment.

Active: Powered. An active crossover is electrically powered and divides the line-level signal prior to amplification. An active speaker includes an active crossover and built-in amplifier.
Actuality: Audio from an announcer speaking.
Amplifier: A component that increases the gain or level of an audio signal.
Balanced Input: A connection with three conductors: two identical signal conductors that are 180 degrees out of phase with each other, and one ground. This type of connection is very resistant to line noise.
Bandpass: A two-part filter that cuts both higher and lower frequencies around a center band. A bandpass enclosure cuts high frequencies by acoustic cancellation and low frequencies by natural physical limitations on bass response.
Bandwidth: In audio, the range of frequencies a device operates within. In video, the range of frequencies passed from the input to the output. Bandwidth can also refer to the transmission capacity of an electronic communications device or system the speed of data transfer,is very important when planning a meeting for the attendees to stay connected.
Bass: Low frequencies those below approximately 200 Hz.
Bi-Wiring: A method of connecting an amplifier or receiver to a speaker in which separate wires are run between the amp and the woofer and the amp and the tweeter.
Boost: To increase, make louder or brighter opposite of attenuate.
Bridging: Combining two channels of an amplifier to make one channel that more powerful. One channel amplifies the positive portion of an audio signal and the other channel amplifies the negative portion, which are then combined at the output.
CD: Compact Disc. Ubiquitous digital audio format. Uses 16-bit/44.1-kHz sampling rate PCM digital signal to encode roughly 74 or 80 minutes of two- channel, full-range audio onto a 5-inch disc.
CD-R: Recordable Compact Disc.
CD-RW: Rewritable Compact Disc.
Channel: In components and systems, a channel is a separate signal path. A four-channel amplifier has at least four separate inputs and four separate outputs.
Coloration: Any change in the character of sound (such as an overemphasis on certain tones) that reduces naturalness.
Crossover: A component that divides an audio signal into two or more ranges by frequency, sending, for example, low frequencies to one output and high frequencies to another. An active crossover is powered and divides the line-level audio signal prior to amplification. A passive crossover uses no external power supply and may be used either at line level or, more commonly, at speaker level to divide the signal after amplification and send the low frequencies to the woofer and the high frequencies to the tweeter.
Crossover Frequency: The frequency at which an audio signal is divided. 80 Hz is a typical subwoofer crossover point and is the recommended crossover point in theatrical and home THX systems. Frequencies below 80 Hz are sent to the subwoofer signals above 80 Hz are sent to the main speakers.
Cut: To reduce, lower opposite of boost.
Decibel (dB): A logarithmic measurement unit that describes a sound`s relative loudness, though it can also be used to describe the relative difference between two power levels. A decibel is one tenth of a Bel. In sound, decibels generally measure a scale from 0 (the threshold of hearing) to 120-140 dB (the threshold of pain). A 3dB difference equates to a doubling of power. A 10dB difference is required to double the subjective volume. A 1dB difference over a broad frequency range is noticeable to most people, while a 0.2dB difference can affect the subjective impression of a sound.
Delay: The time difference between a sonic event and its perception at the listening position (sound traveling through space is delayed according to the distance it travels). People perceive spaciousness by the delay between the arrival of direct and reflected sound (larger spaces cause longer delays.
Diaphragm: The part of a dynamic loudspeaker attached to the voice coil that produces sound. It usually has the shape of a cone or dome.
Diffusion: In audio, the scattering of sound waves, reducing the sense of localization. In video, the scattering of light waves, reducing hot spotting, as in a diffusion screen.
Digital Audio Server: Essentially a hard drive, a digital audio server stores compressed audio files (like MP3 or WMA). Most include the processing to make the files, and all have the ability to play them back.
Direct-Stream Digital: A format for encoding high-resolution audio signals. It uses a 1-bit encoder with a sampling rate of 2,822,400 samples per second (verses 44,100 for CD). Used to encode six high-resolution channels on SACD.
Dispersion: The spread of sound over a wide area.
Distortion: Any undesired change in an audio signal between input and the output.
DNR: Dynamic Noise Reduction. A signal-processing circuit that attempts to reduce the level of high-frequency noise. Unlike Dolby NR, DNR doesn't require preprocessing during recording.
Dolby B: A noise-reduction system that increases the level of high frequencies during recording and decreases them during playback.
Dolby C: An improvement on Dolby B that provides about twice as much noise reduction.
Dolby Digital: An encoding system that digitally compresses up to 5.1 discrete channels of audio (left front, center, right front, left surround, right surround, and LFE) into a single bitstream, which can be recorded onto a DVD, HDTV broadcast, or other form of digital media. When RF-modulated, it was included on some laser discs, which requires an RF-demodulator before the signal can be decoded. Five channels are full-range the .1 channel is a band-limited LFE track. A Dolby Digital processor (found in most new receivers, preamps, and some DVD players) can decode this signal back into the 5.1 separate channels. Most films since 1992`s Batman Returns have been recorded in a 5.1 digital format, though a number of films before that had 6-channel analog tracks that have been remastered into 5.1.
Dolby EX: An enhancement to Dolby Digital that adds a surround back channel to 5.1 soundtracks. The sixth channel is matrixed from the left and right surround channels. Often referred to as 6.1. Sometimes referred to as 7.1 if the system uses two surround back speakers, even though both speakers reproduce the same signal. Software is backwards-compatible with 5.1 systems, but requires an EX or 6.1 processor to obtain additional benefit.
Dolby Pro Logic: An enhancement of the Dolby Surround decoding process. Pro Logic decoders derive left, center, right, and a mono surround channel from two-channel Dolby Surround encoded material via matrix techniques.
Dolby Pro Logic II: An enhanced version of Pro Logic. Adds improved decoding for two-channel, non-encoded soundtracks and music.
Driver: A speaker without an enclosure also refers to the active element of a speaker system that creates compressions and rarefactions in the air.
DSP: Digital Signal Processing. Manipulating an audio signal digitally to create various possible effects at the output. Often refers to artificially generated surround effects derived from and applied to two-channel sources.
DTS: Digital Theater Systems. A digital sound recording format, originally developed for theatrical film soundtracks, starting with Jurassic Park. Records 5.1 discrete channels of audio onto a handful of laser discs, CDs, and DVDs. Requires a player with DTS output connected to a DTS processor.
DTS ES: An enhanced version of the 5.1 DTS system. Like Dolby's Surround EX, a sixth channel is added. In some cases (DTS ES Discrete), the sixth channel is discrete. Software is backwards-compatible with 5.1 systems, but requires an ES or 6.1 processor to obtain additional benefit. Neo: 6 is a subset of DTS ES that creates 6.1 from material with fewer original channels.
Dynamic Range: The difference between the lowest and the highest levels in audio, it&'s often expressed in decibels. In video, it's listed as the contrast ratio.
