Electro-Voice X1-212/90, Руководство по установке

Introduction
The X1 and X2 loudspeaker system line-array elements by Electro-Voice represent an
important step in line-array technology for small- to large-scale fixed-installation and live
sound reinforcement. The various models are designed to significantly simplify the physical
assembly of a line array. Also, X1 in passive mode may be designed so that up to three
elements are powered from one (1) amplifier channel, the necessary crossover and EQ
functions accomplished with sophisticated internal passive networks. X2 is designed to
operate in Bi-amp mode only. The individual loudspeaker drivers, Hydra planar-wave
generators, acoustic waveguides, enclosures and rigging hardware were all designed
specifically for the X1 and X2 product line to not only achieve the highest acoustic output with
the highest fidelity, but also produce a precise wave front from each element to achieve state-
of-the-art line-array performance. The X12 subwoofer elements are designed to compliment
the performance of X1 and X2 full-range elements in applications where additional low-
frequency output is desired.
Although the X1 and X2 full-range elements are not physically symmetrical, their acoustic polar
responses are substantially symmetrical. Thus, stereo left and right arrays or left-center-right
arrays may be constructed with the elements in their normal right-side-up orientation.
