Ronald Reagan Building and International Trade Center, that is. The Washington, D.C., facility has published a brochure on its communication, broadcast, and presentation technologies — not the typical vague promotional copy promising “high-speed connections,” but actual facts. Do you need to know how many triaxial cable lines come into the Atrium Ballroom (five), the amphitheater (seven), the exhibit hall (none)? Do you need to know what kind of mixing console is in the audio command booth (a 40-plus channel Crest)? Or which meeting rooms have a closed circuit television system (all)? Finally, a brochure that doesn't spare us the details. For a copy, call Linda Meyer,director, at (202) 312-1300.
