PURPOSE:To attain mixing by converting a sound signal into an optical signal, transmitting it and mixing it optically so as to transmit the signal while keeping the quality of the sound signal without being affected with electromagnetic induction fault. CONSTITUTION:In outputting a sound analog signal from sound signal generating sources 1a-1d, it is subjected to analog intensity modulation by electrooptic signal converters 2a-2d and converted into an optical signal. The optical signal is transmitted through optical fibers 3a-3d, mixed optically by an optical mixing device 4 and outputted. The output is fed to a speaker 6 via an amplifier 5. |
