Patent

CA 2150130

An audio distribution system includes a main control unit for distributing audio signals to a plurality of zones using a remote programming unit and a plurality of zone input panels for commanding the types of audio signals to be routed to the various zones. The remote programming unit includes a plurality of input switches, and a command sending circuit responsive to the input switches for sending a command selected by the switches to control the audio in a selected one of the zones. Each of the zone input panels includes a receiver for receiving the commands from the remote programming unit. The receiver is used to couple the received command to the main control unit. The main control unit receives the command from the zone input panel and controls the audio for the selected zone independently from the other zones.

Système de distribution de signaux sonores comprenant une unité de commande principale qui sert à distribuer des signaux sonores dans plusieurs zones, à l'aide d'une unité de programmation éloignée et de plusierus panneaux d'entrée propres aux zones, pour commander les types de signaux sonores à acheminer jusqu'aux diverses zones. L'unité de programmation éloignée comprend plusieurs commutateurs d'entrée et un circuit d'émission de commandes qui réagit aux commutateurs d'entrée pour commander le signal sonore dans une zone sélectionnée. Chaque panneau d'entrée associé à une zone comprend un récepteur qui reçoit les commandes de l'unité de programmation éloignée. Ce récepteur sert à coupler la commande reçue à l'unité de commande principale. Cette dernière reçoit la commande du panneau d'entrée associée à une zone et commande le signal sonore pour la zone sélectionnée indépendamment des autres zones.
