User manual ELECTRO-VOICE A-N683 DATASHEET

[. . . ] This combination results in substantially improved vocal clarity and presence with a smooth response throughout the vocal range up to 20, 000 Hz. The horn and driver are nested inside the midbass phase plug assembly to minimize interference in the mid-bass band. The mid-bass driver in the Xcn is the ND12A, which is a 30. 5-mm (12-in. ) midbass driver that features a powerful new neodymium motor structure that was optimized for maximum horn-loaded efficiency and reduced power compression. A new Kevlar ®-reinforced cone assembly provides a smooth response with reduced cone break up. [. . . ] The test parameters are as follows: High-Frequency Section PE(MAX): Test Voltage: RSR (1. 15 RE): 75 watts 30. 1-volts rms 60. 2-volts peak 12. 1 ohms Mid-Bass-Frequency Section PE(MAX): Test Voltage: RSR (1. 15 RE): 300 watts 45. 5-volts rms 91. 0-volts peak 6. 90 ohms Amplifier Recommendations Power amplifiers with the following ratings are recommended for use with the Xcn loudspeaker systems: HF: 800 watts per channel into 8 ohms Xcn T wo-W MB/HF System ay 93-volts rms short term 132-volts peak MB: 800 watts per channel into 8 ohms 93-volts rms short term 132-volts peak Xcn loudspeakers may be paralleled with other Xcn systems as long as the amplifiers can drive the lower impedances. To maintain a sufficient damping factor with long cable runs, amplifier loads of four ohms per channel are recommended. The Electro-Voice P3000 amplifiers are ideal for powering the X-ArrayTM systems. Crossover, Equalization and Signal Delay Controller The Xcn is a two-way active loudspeaker system requiring an active crossover, equalization and signal delay controller. For basic applications, the Electro-Voice Dx38 2-in/4-out controller is recommended. For more sophisticated applications, the Klark Teknik DN8000 2-in/ 5-out controller is recommended. Linkwitz-Riley crossover filters with a minimum slope of 24-dB per octave at 125 Hz and 1, 760 Hz are recommended. Both the Dx38 and the DN8000 offer appropriate filtering, equalization and signal delay capabilities to provide optimum performance of the X-ArrayTM loudspeaker systems. Digital parameter settings for both controllers are available upon request. Electrical Connection and System Wiring Two paralleled Neutrik 8-pin Speakon® connectors are used for electrical connection to the Xcn loudspeakers with the following pin assignments: HF: MB: Pins 4 Paralleled Pins 3 Paralleled which use Pins 1 and 2, but not Pins 3 and 4) to be paralleled with an Xcn, allowing all eight conductors to be used with a single cable run to the amplifiers. Note that when four Xcn systems are jumped from one to another, the amplifier home-run cable will have four high-frequency drivers on Pins 4 (for a 4-ohm load) and four mid-bass drivers on Pins 3 (for a 4-ohm load). ElectroVoice, 600 Cecil St. , Buchanan, MI 49107 USA, 616/695-6831 or 800/234-6831 Xrhp Pickup Hinge: Two Xrhp pickup rigging hinges are used to create custom rigging assemblies to attach to the rear of the top enclosure in a column when an ATM grid is not used. Each hinge consists of one precision-machined steel rigging-track fitting with an alloy-steel chain. Electro-Voice, 600 Cecil St. , Buchanan, MI 49107 USA, 616/695-6831 or 800/234-6831 Xrhl Linking Hinge: Two Xrhl linking rigging hinges are used to link two enclosures together at the rear. Each hinge consists of two precision-machined steel rigging-track fittings connected by a heavyduty steel hinge. Electro-Voice, 600 Cecil St. , Buchanan, MI 49107 USA, 616/695-6831 or 800/234-6831 Xrsl Long Rigging Steel Straps: Two Xrsl long rigging straps are used at the front of two enclosures to adjust their relative vertical angles. The Xrsl may also be used to attach the front of the top enclosure to the ATM grid when upward angles are not required. Each all-steel strap consists of two New Haven NH32102-2 double-stud fittings connected by black plastic-coated wire rope.

Wilmington Ave. , Carson, CA 90810 USA, 310/834-5914 Xrss Short Rigging Steel Straps: Two Xrss short rigging straps are used to attach the front of the top enclosure to the ATM grid. The Xrss may also be used at the front of two enclosures when a limited range of vertical angles are required. The all-steel Xrss utilizes the same construction as the Xrsl.
