摘要： A distributed stereo system includes two (or more) speakers; a source of audio signals; an amplifier in the same room as the speakers that drives the speakers; and a mains-operated electrical power supply to power the amplifier. The amplifier is remote from the signal source and power supply and is connected to the signal source and power supply by means of a category 5, four-pair twisted cable or similar, which provides right and left channel audio signals from the signal source to the amplifier and DC power from the power supply to the amplifier. A distributed intercom system features a bi-directional intercom hub; a mains-operated power supply; and two or more remote modules each having an amplifier and speaker. The modules are connected to the hub via category 5 cable or similar, which carries audio signals between the hub and the modules and power from the supply to the modules.

摘要： This invention concerns a distributed stereo audio system. Distributed stereo audio systems are used to provide stereo sound to several rooms or areas from a single source of signal. The system includes two or more speakers for the broadcast of stereo audio signals; a source of stereo audio signals; a stereo amplifier to amplify stereo audio signals and drive the speakers; and a mains operated electrical power supply to provide power to the amplifier. The amplifier is located in the same room as the speakers, and remote from the signal source and power supply. The amplifier is connected to the signal source and power supply by means of a category 5 four pair twisted cable which provides, in respective twisted pairs, right channel audio signals from the signal source to the amplifier, left channel audio from the signal source to the amplifier, DC power from the power supply to the amplifier, and control signals from the amplifier to the signal source.

摘要： This invention concerns a distributed stereo audio system (1). Distributed stereo audio systems are used to provide stereo sound to several rooms or areas from a single source of signal. The system includes two or more speakers (2, 3) for the broadcast of stereo audio signals; a source of stereo audio signals; a stereo amplifier (4) to amplify stereo audio signals and drive the speakers; and a mains operated electrical power supply (10) to provide power to the amplifier. The amplifier is located in the same room as the speakers, and remote from the signal source and power supply. The amplifier is connected to the signal source and power supply by means of a category 5 four pair twisted cable (11) which provides, in respective twisted pairs, right channel audio signals (12) from the signal source to the amplifier, left channel audio (13) from the signal source to the amplifier, DC power (14) from the power supply to the amplifier, and control signals (20) from the amplifier to the signal source.
