Electro-Voice X-Array XCN Manuals

Description The X-Array™ product line represents im- portant advancements in concert-sound- reinforcement technology. The design goals called for the highest acoustic out- put capability with the highest fidelity in lightweight, compact enclosures that were easy to array. The development began with a clean sheet of paper and took an inte- grated approach. The individual loud- speaker drivers, horns, enclosures, rigging hardware and system configurations were designed from the ground up specifically for this high-performance application. The Xcn is an active near-field, two-way, MB/HF loudspeaker system with a rotat- able 60° x 40° coverage pattern. The high- frequency and mid-bass sections are horn loaded with one driver in each frequency band, and the HF horn/driver combination is mounted coaxially inside the mid-bass horn. The mid-bass and high-frequency sections are identical to that of the full- size Xn X-Array™ system. The horns and drivers were designed as part of the Xcn development and represent a step forward in state-of-the-art loudspeaker design in terms of high acoustic output with low distortion and low power compression. Electro-Voice engineers developed a new technology dubbed Ring-Mode Decoupling (RMD™) to substantially im- prove clarity and intelligibility by reduc- ing both linear and nonlinear resonance modes that color the sound. The high-frequency driver in the Xcn is the ND5, which is a 3.56-mm (1.4-in.) exit high-frequency compression driver that features a powerful neodymium motor structure that was optimized for maximum efficiency and reduced power compression. A new 76.2-mm (3.0-in.)-diameter titanium diaphragm assembly provides increased in- stantaneous peak output capability and reduced dome breakup. The ND5 is mounted on a 60° x 40° rotatable constant- directivity horn. This combination results in substantially improved vocal clarity and presence with a smooth response through- out the vocal range up to 20,000 Hz. The horn and driver are nested inside the mid- bass phase plug assembly to minimize in- terference in the mid-bass band. The mid-bass driver in the Xcn is the ND12A, which is a 30.5-mm (12-in.) mid- bass driver that features a powerful new neodymium motor structure that was opti- mized for maximum horn-loaded efficiency and reduced power compression. A new Kevlar®-reinforced cone assembly pro- vides a smooth response with reduced cone break up. The ND12A is mounted on a mid-bass horn that has a coverage pat- tern that transitions smoothly into the ro- tatable 60° x 40° high-frequency pattern. The mid-bass phase plug provides opti- mal loading for the ND12A driver, deliver- ing smooth response and extended effi- ciency up to 2,000 Hz. This combination results in improved vocal intelligibility and clarity with a smooth response from the lower-to-mid vocal range. Ring-Mode Decoupling, (RMD™) is a technique utilized and named by Electro- Voice to describe a process used to im- prove sound quality in loudspeaker sys- tems. RMD™ offers a solution to a very fundamental problem. It has long been rec- ognized that two different loudspeaker systems can sound different even though they both may be equalized to have the same frequency response. This difference is due to a variety of resonances, or ring modes, that color the sound. Although this ringing may be very low in level compared to the program material, it is still audible. The source of these resonances may be mechanical or acoustical in nature or a com- bination of both. In addition, they may be linear or nonlinear, resulting in their char- acter changing with level. Furthermore, these ring modes may be aggravated when multiple loudspeaker enclosures are as- sembled into arrays. The result is a colora- tion that decreases intelligibility and clar- Xcn X-Array™ Two-Way, MB/HF System • MB and HF sections are identi- cal to Xn • Ring-Mode Decoupling (RMD™) provides accurate transient detail • Near-field 60° x 40° rotatable coverage pattern • Neodymium ND5 HF and ND12A MB drivers • Unique rear-hinge rigging • Enclosure shell and rigging identical to all of the half-size X-Array™ systems
