Title:
【発明の名称】制御可能音量オーバライドを有するオーディオ分配システム
Document Type and Number:
Japanese Patent JPH08505034
Kind Code:
A
Abstract:
A signal distribution and communication arrangement includes a main control unit remotely located and electrically coupled to a volume control panel. The volume control panel is located near a speaker, and the main control unit sends substantially continuous audio signals or an interrupting audio signal to the volume control panel for playing via the speaker. These signals can be sent on the same conductor or separate conductors. When the interrupting audio signal is present, a voltage or current source provides a level from the main control unit to the volume control panel to indicate that a volume override circuit should be engaged. Upon engagement of the volume override circuit, the interrupting audio signal is passed through to the speaker at a prescribed signal level, regardless of the volume control setting on the volume control panel.
