MULTI-CHANNEL BROADCASTING SYSTEM CONTROLLABLE INDIVIDUAL SOUND SOURCE OUTPUT

摘要

PURPOSE: A diversification broadcasting system for controlling individual sound source for infinite expansion is provided to minimize volume of a system and to increase output region. CONSTITUTION: A sound source input unit(110) of a system control apparatus converts a sound source received from sound source generators into a sound source necessary for broadcasting. A sound source output unit of a system control device transmits the modulated sound source. A system controller of the system controller controls the sound source input unit and the sound source output unit. An audio bus(120) of the system controller transmits the sound source to the connected sound source output unit.
