User manual ELECTRO-VOICE EVI-12 EDS

[. . . ] The high-frequency complement consists of a 25. 4-mm (1. 0-in. ) exit compression driver utilizing a new small-format Vari Intense® horn. Vari Intense® is a revolutionary patented6 technology that throws a 6-to 10-dB hotter signal to the back of the room. This compensates for the drop in SPL over the longer distance to the back of the room (25 feet for the short throw and about 70 feet for the long throw in a typical room). [. . . ] Power handling shall be 250 watts of pink noise with a 6-dB crest factor for eight hours, band limited from 45 Hz to 20 kHz. 3 Frequency response shall be smooth and uniformly usable from 45 Hz to 20 kHz. Pressure sensitivity shall be 99. 5 dB SPL when measured at one meter on axis with EVI-12 Full-Range Loudspeaker one watt of band-limited pink noise from 45 Hz to 20 kHz. The enclosure shall be constructed of 19-mm (0. 75-in. ) 7-ply birch plywood and shall be heavily braced and lined with sound-absorbent glass wool. The system shall include five 3/8-16 mounting points to accommodate either a three-point rigging system or an optional U-bracket with pull-up point. The finish of the enclosure shall be textured black or white and a removable black or white metal grille shall be provided. The dimensions of the enclosure shall be 554 mm (21. 8 in. ) high by 356 mm (14. 0 in. ) wide by 699 mm (27. 5 in. ) deep. The loudspeaker system shall weigh 22 kg (48 lb). The loudspeaker system shall be the Electro-Voice EVI-12 black or EVI-12 white.

[. . . ] This system rating is patterned after the ANSI/EIA RS-426-A method where the test signal is pink noise with a 6-dB crest factor over the bandwidth of the system, with power calculated using E2/RE x 1. 15, for 8 hours. This measurement made under the same conditions as pressure sensitivity, and takes into account any power-compression effects due to nonlinearities in the system. 5. The distortion at any given frequency may be found by graphically taking the difference between the fundamental and harmonic, and adding the number of decibels which the harmonic has been raised on the graph and apply the formula: percent distortion = 100 x 10 (-difference in dB/20) 6.
