Summary: | PROBLEM TO BE SOLVED: To easily connect a commercial ungenuine head unit having an abundant sound source to a genuine power amplifier of a super live sound system irrespective of the presence or absence of a remote terminal and to remove noise from a speaker at the time of connection. SOLUTION: A micro computer 22 senses connection of an ACC power source and transmits an instruction for supplying the power of a power amplifier 31 to a microcomputer 32. A microcomputer 23 simultaneously senses connection of the ACC power source and transmits an instruction for operating the muting circuit of the power amplifier 31 to a microcomputer 33. The microcomputer 22 thus senses disconnection of the ACC power source and transmits an instruction for cutting off power of the power amplifier 31 to a microcomputer 32. COPYRIGHT: (C)2004,JPO |
