User manual ELECTRO-VOICE CDP-850T EDS

[. . . ] The 150° horizontal by 110° vertical dispersion pattern is beneficial in many applications requiring a wide coverage pattern. Furthermore, excellent loading is maintained to a low-frequency cutoff of 180 Hz. Architects' and Engineers' Specifications The loudspeaker shall be of the integrated driver and horn style, utilizing two coaxial horns coupled to opposite sides of the driver diaphragm and a larger horn compression molded from fiberglass, a zinc die-cast front horn and phenolic-constructed inner horns.

For horizontal dispersion, (or for mounts where the bracket mounting holes must be vertical), move bracket to the rear mounting position. The horn can be mounted in a variety of horizontal and vertical configurations by using adjustments of the swivel connections (bracket to horn). Frequency Response Figure 3 shows the axial frequency response of the 850T. It was measured at a distance of 1 meter, using a swept sine wave. Transformer A transformer and power selector switch are installed in the rear housing. Power taps for the transformer are listed in Table 1. Polar Response The directional characteristics of the 850T, with driver attached, were measured by running a set of horizontal/vertical polar responses, in a large anechoic chamber, at each one-third-octave center frequency. The test signal was one-third-octave pseudo-random pink noise centered at the indicated frequencies. [. . . ] · www. telex. com © Telex Communications, Inc. 02/2001 Part Number 38109-840 Rev A U. S.
