Abstract
In an acoustic device for custom installation in which one can listen to music in a zone which is different from a zone where an acoustic device main unit, e.g., an audio amplifier or a CD player, is located, turning on or off of loudspeakers is remote-controlled in one zone. An remote control signal from a remote-controller is received by a remote controller signal receiver in that zone and transmitted to a switch control section (microcomputer). The switch control section identifies the particular zone in which the remote control signal has been produced and switches a transmission on/off switch to turn on or off the loudspeakers in that zone. The acoustic device also includes independent signal paths, selective mixed signal supply paths which selectively combines the remote control signals provided from the plural zones and supplies the selective combined remote control signal and all mixed signal supply path which combines all the remote control signals and supplies the combined remote control signal and a remote control signal can be supplied via one these signal paths depending upon the situation of use of acoustic devices whereby some acoustic devices can be controlled only …
