Wilshire Blvd. , Suite 362 Oklahoma City, Oklahoma 73116 www. altecpro. com INSTALLATION AND WIRING Although the SLC408-16T can be mounted into a sheetrock or plaster ceiling, the following installation procedure is intended for suspended tile ceilings. Note: We recommend that you order the mounting ring (SLC-RING), not included, when installing the SLC408-16T into a sheetrock or plaster ceiling. Place ceiling tile, finished side facing up, over the flat, 12 in. (559 mm) diameter opening of a container such as a Rubbermaid® 32 gallon Brute® model 2632. Locate the approximate center of the mounting hole that is to be cut, and mark this spot on the ceiling tile. This transformer shall have an insertion loss of < 0. 6 dB. The loudspeaker component, switch and transformer shall be assembled into a moisture resistant black-painted steel enclosure with internal damping material. The enclosure diameter shall be 9. 31 in. (236 mm), the enclosure's baffle diameter shall be 11. 75 in. (298 mm), and the enclosure's depth shall be 7. 85 in. The loudspeaker system shall include a 12. 75 in. (324 mm) diameter, one-piece, snap-on, off-white-painted steel grille; and a 23. 75 in. (356 mm) wide, 20 gauge galvanized steel tile bridge. The loudspeaker system shall be the Altec Lansing Professional model SLC408-16T. Frequency Response 110 100 dB SPL (ref: 20 Pa) 90 80 70 SPECIFICATION NOTES 1 60 20 50 100 200 500 1k 2k 5k 10 k 20 k Frequency (Hz) 2 3 4 5 6 7 The frequency response of the loudspeaker system is measured at a distance of no less than 3 meters to obtain full range data. The level is then corrected to be equivalent to a 2. 83 V 1 m measurement. A near field measurement of the system is performed for frequencies below 500 Hz. [. . . ] The data is measured and level corrected in a manner consistent with note 1. The power handling capacity of the loudspeaker system is tested using a full range form of AES Standard 2-1984. The test stimulus is band limited (40 Hz ­ 16 kHz) pink noise with a 6 dB crest factor. The applied RMS voltage is determined using the minimum impedance of the system. [. . . ]
