(See the Amplifier Recommendations section.) Power-Handling Capabilities The Xi-2181 systems are rated as per the “ANSI/EIA RS-426-A Loudspeaker Power- Rating, Full-Range Test,” which uses a shaped-random-noise signal to simulate typical music to test the mechanical and thermal capabilities of the loudspeakers. A digital crossover was used to provide the appropriate filtering and equalization. The test parameters are as follows: Low-Frequency Section (Pins 1 and 2 par alleled): PE(MAX): 1,200 watts Test Voltage: 58.7-volts rms 117.4-volts peak RSR (1.15RE): 2.88 ohms Amplifier Recommendations Power amplifiers with the following ratings are recommended for use with the Xi-2181 loudspeaker systems: LF: 800 watts into 8 ohms 91-volts rms short term 130-volts peak Xi-2181 loudspeakers may be paralleled with other Xi-2181 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-Array™ systems. Crossover, Equalization and Signal Delay Controller The Xi-2181 is intended to be used with other X-Array Install™ loudspeaker systems to construct full-range arrays as an active system requiring an active crossover, equalization and signal delay controller. For basic applications, the Merlin ISP100, or the Electro- Voice Dx34A 2-in/4-out controller is recommended. The Klark Teknik DN8000 2in/ 5-out controller is also recommended. Linkwitz-Riley crossover filters with a minimum slope of 24 dB per octave at 125 Hz are recommended, and infrasonic filter pro tection at 32 Hz or higher with a minimum slope of 12-dB/octave is recommended in the low-frequency section. The ISP100 as well as the Dx34A and the DN8000 offer appropriate filtering, equalization and signal delay capabilities to provide optimum performance of the X-Array Install™ loudspeaker systems. Digital parameter settings for all controllers are available upon request. Electrical Connection and System Wiring Two paralleled Neutrik 8-pin Speakon® connectors are used for electrical connection to the Xi-2181 loudspeakers with the following pin assignments: LF1: Pins 1 Paralleled LF2: Pins 2 Paralleled The Xi-2181 wiring diagram is shown in Figure 7. Since the connectors are paralleled, it does not matter which connector is used as the input or output when paralleling Xi-2181 systems. Although Pins 3 and 4 are not used by the Xi-2181 systems, they are paralleled on the input panel. This allows an X-Array Install™ MB/HF box to be paralleled with an Xi-2181, allowing all eight conductors to be used with a single cable run to the amplifiers. Note that, when two Xi-2181 systems are jumped from one to another via the input/output connections, the amplifier home-run cable will have two woofers on Pins 2 (for a 4-ohm load) and two woofers on Pins 1 (for a 4-ohm load). 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-2181 loudspeaker system includes flying hardware, a unique two-point 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 Xi-2181 Bass System Xi-2181 Bass System quickly, and offers such flexibility in the vertical angling of cabinets that pull-up points are usually unnecessary. Furthermore, all of the flying Xi loudspeaker 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 limit(for an 8:1 safety factor) 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 side 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-tobottom and side-to-side metal straps link the rigging track inside the enclosure. CAUTION: The Xi lo...
