Nowadays businesses require separate spaces just for conferences and meetings where high ranking executives can discuss and provide direction for the company. For this purpose a big conference room is necessary, as well as a proper audio conference system to allow everyone to communicate and interact with each other through audio conference microphones and speakers. Audio conference systems are comprised of audio conference chairman microphones, audio speaker microphones, all types of loudspeaker systems (loudspeaker enclosures), and amplifiers plus cables required to broadcast in one or several rooms simultaneously. The selection of microphone and speakers depend on the size of the meeting or conference room along with its use by the audience: listening, speaking or both.
