Title (EN) POWER AMPLIFIER EQUIPMENT BASED ON DMX PROTOCOL
(FR) ÉQUIPEMENT AMPLIFICATEUR DE PUISSANCE FONDÉ SUR LE PROTOCOLE DMX
(ZH) 一种基于DMX协议的功放设备
Abstract:
(EN) A power amplifier equipment based on DMX protocol includes an audio input interface, a volume control circuit connected to the audio input interface, a power amplifier circuit and an audio output interface connected to the power amplifier circuit. The said volume control circuit includes the DMX signal reception processing circuit and the electronic volume circuit. The said power amplifier equipment supports the DMX protocol, which is controlled by using DMX signals, so that the power amplifier equipment and digital lighting equipment can cooperate under the control of DMX signals to achieve the integrating control of sound and light for performance scene.
(FR) L'invention porte sur un équipement amplificateur de puissance fondé sur le protocole DMX qui comprend une interface d'entrée audio, un circuit de commande de volume connecté à l'interface d'entrée audio, un circuit amplificateur de puissance et une interface de sortie audio connectée au circuit amplificateur de puissance. Ledit circuit de commande de volume comprend le circuit de traitement de réception de signal DMX et le circuit de volume électronique. Ledit équipement amplificateur de puissance supporte le protocole DMX, qui est commandé par utilisation de signaux DMX, de sorte que l'équipement amplificateur de puissance et un équipement d'éclairage numérique peuvent coopérer sous la commande de signaux DMX afin de réaliser la commande intégrée de sons et lumières pour une scène de spectacle.
