User manual ELECTRO-VOICE XI-1082 EDS

[. . . ] RMDTM Ring-Mode Decoupling is the same advanced technology built into the X-ArrayTM touring series. RMDTM produces substantially improved tonal character and fidelity whether operated at low or extremely high sound pressure levels. Mechanical solutions resolve mechanical issues, acoustical solutions address acoustical modes found in all sound reinforcement systems. [. . . ] It is the responsibility of the installer to ensure the Xi-1082 is safely installed in accordance with applicable regulations. If the Xi-1082 is suspended, Electro-Voice strongly recommends that the system be inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately. Architects' And Engineers' Specifications The loudspeaker system shall be a two-way, vented type, consisting of a 203-mm (8. 0 in. ) direct-radiating driver with a compression driver with a 25. 4-mm (1. 0 in. ) exit mounted on a 90° x 40° constant-directivity horn. Power handling shall be 175 watts of pink noise with a 6-dB crest factor for eight hours (as per ANSI/EIA RS-426-A 1980 standard). Frequency response shall be smooth and usable at high SPL levels from 50 Hz to 20 kHz with pressure sensitivity of 91 dB for 1 watt at 1 meter. The system shall have a distribution pattern with 90° nominal horizontally from 3 kHz to 16 kHz and 40° nominal vertically from 3 kHz to 20 kHz. The loudspeaker enclosure shall be constructed of 18-mm thick plywood, trapezoidal in shape, internally lined with sound-absorbing material. The finish of the enclosure 2 X-Array InstallTM Xi-1082 Loudspeaker System shall be textured black.
