A convention, in the sense of a meeting, is a gathering of individuals who meet at an arranged place and time in order to discuss or engage in some common interest. The most common conventions are based upon industry, profession, and fandom. Trade conventions typically focus on a particular industry or industry segment, and feature keynote speakers, vendor displays, and other information and activities of interest to the event organizers and attendees.
Professional audio & video equipment are essential to put together a successfull event. Many conventions also involve seminar, workshops or conferences where simultanous interpreting and interpreting equipment will be needed.
