User manual ELECTRO-VOICE QRX TWIST & SHOUT POSTER

[. . . ] The compression driver shall be mounted on a 75-degree x 50-degree asymmetrical constant directivity horn with a factory delivered position of 15 degrees up/35 degrees down/50 degrees horizontal configuration. The horn shall be constructed of a material and design so as to be capable, structurally, of supporting the HF driver without any internal braces or suspensions, allowing a full 360-degree rotation of the horn. The enclosure shall be included, providing crossover filters for component band passes and nominal system voicing. The input panel shall incorporate two switches, allowing external configuration between biamped or passive operation. [. . . ] Input connections shall be accommodated with two paralleled NL4 female Speakon ® connectors. Loudspeaker system frequency response shall be no less than 52 Hz to 16 kHz (-3 dB) measured on axis. The loudspeaker shall produce a sound pressure level (SPL) of 102 dB on axis at 1 meter with a power input of 1 watt and shall be capable of sustaining a full power, long-term average output of 129 dB on axis at 1 meter (135 dB peaks). The full-range system, with passive network engaged, shall handle 600 watts of amplified power long-term in compliance with AES-EIA standards and have a nominal impedance of 4 ohms. The loudspeaker enclosure shall be constructed of 13-ply voidfree cross-grain-laminated Birch plywood. It shall be finished in black or white acrylic paint or available unfinished. Handles shall be recessed within the sides of the enclosure and of such design to allow safe handling from any direction. The top and bottom of the enclosure shall have L-track rigging installed and the rear shall have a pull-up point. Three single studded ancra fittings rated for overhead use shall be included with each loudspeaker system. +15°/-35° Dimensions Height . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
