User manual ELECTRO-VOICE XI-SERIES

[. . . ] TM TM Delivering the best possible sound to every seat in the house R X-ArrayTM: Ring-Mode Decoupling (RMDTM), for the best vocals you have ever heard. X-ArrayTM 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-SeriesTM employs neodymium magnetics and a rigging system designed and especially appropriate for large, world-class touring arrays. [. . . ] As a result, vocal intelligibility and musical clarity suffer. (The typical compact 60° x 40° horn, about 12 inches high, begins to expand beyond its rated 40° vertical coverage angle at about 2, 000 Hz, well above a major portion of the vocal range. ) The mid-bass horn in the Xi-2153/64F is large enough (about 19 inches square) to control its 60° x 40° coverage to about 800 Hz, but ElectroVoice engineers wished to do The Xi-2153/64F may be crossed over traditionally at 125 Hz and 1, 760 Hz, with reduced vertical directivity control below 800 Hz. When the 48-inch height of the Xi-2153/64F is excessive, consider the 36-inch Xi1153/64F (one 15-inch woofer) in dipole configuration. A DL-type 12-inch mid-bass driver features RMDTM and is coupled to the 19-inch mid-bass horn. Dual EVX-155 15-inch woofers offer performance to 45 Hz, appropriate for numerous systems without lowfrequency enhancement. The DH6 large-format compression driver with RMDTM provides superior and level-stable upperfrequency detail. It loads into a rotatable 60° x 40° HF horn. Providing more RMDTM, the horn is coaxially but asymmetrically positioned within the mid-bass horn to suppress unwanted acoustic resonances and is fully shrouded to preserve mid-bass wave-front detail. Xi-2123/106F: Three-way, dual-12-inch 100° x 60° full-range system, tripole configurable The Xi-2123/106F has a wide, 100° x 60° coverage pattern for down-fill and distributed applications. The 60° vertical angle is particularly appropriate when mounting height is too low for the more conventional 40° angle. The Xi-2123/106F may be used in tripole configuration with Merlin® ISP-100 processing, where overlap in the 250- to 550-Hz range of the MB horn and the dual, flanking woofers extends vertical pattern control to 160 Hz. Such wide-band control of directivity increases voice "F" suffix indicates flying configuration. Systems shown without grille. Xi-1183/64F and Xi-2183/64F: Three-way, 18-inch 60° x 40° full-range systems for conventional crossover and increased LF output In situations where acoustic conditions are sufficiently ideal and/or the feedback potential PAGE 4 Xi-1183/64F Two- ways with special protection option intelligibility and musical clarity in reverberant spaces and reduces the possibility of feedback beneath the systems. The Xi-2123/106F may also be conventionally crossed over, without LF/MB overlap, with decreased vertical directivity control. The dual DL12-type woofers, modified for increased excursion and overall output, extend bass response of the Xi-2123/64 to 60 Hz. The rotatable, 14-inch square mid-bass horn loads a DL-type 10-inch cone transducer. A DH6 large-format compression driver drives the rotatable HF horn. Compact, two-way full-range systems for stand-alone use in small- to medium-sized installations and to complement the performance of the large Xi-SeriesTM systems. Optional Merlin® ISP-100 processing provides unusually effective protection against component failure, for maximum output from two-way direct-radiating systems. Merlin® ISP-100: Excursionsmart, look-ahead limiting For the biamp-only Xi-SeriesTM two-way systems (Xi-1122 and Xi-1152), the optional Merlin® ISP-100 provides the ultimate in sonically unobtrusive yet ultraeffective protection against driver destruction. Merlin® extracts maximum output from these ultracompact, directradiating Xi-SeriesTM systems. Integral carrying handles and stand-mount adapter, in addition to the L-track top and bottom rigging, facilitate a wide range of portable and fixed applications. Xi-1123/106F: Three-way, 12-inch 100° x 60° fullrange system, dipole configurable When extended-frequency vertical directivity control is desired but vertical clearance is limited, the Xi-1123/106F should be considered. At 32 inches rather than 40 inches high, the Xi-1123/106F has one DL-type 12-inch woofer adjacent to the MB horn. With the Merlin® ISP-100 providing MB/LF overlap in the 250­ to 550-Hz range, vertical directivity is controlled to 250 Hz. [. . . ] For the Xi-SeriesTM family of loudspeakers, typical configurations include: · 2 x 4 (two in/four out) for a stereo two-way system · 2 x 6 for a stereo three-way system · 2 x 8 for a stereo three-way system with dual low-frequency enhancement outputs. Additional Merlin® ISP-100's can be used to augment loudspeaker management with signal routing to fit many performing arts, church and other applications. The power and versatility of Merlin® are best displayed when applied to the management of Xi-SeriesTM speaker systems: · Two-element (dipole) and three-element (tripole) linearray configurations extend vertical coverage control to as low as 125 Hz. (See pages 4 and 5 for full explanations and the models that apply. ) · Excursion-smart protection against mechanical overdrive of system components. [. . . ]
