Abstract

PURPOSE:To make it possible for conference attendees to listen to the voice of a speaker closely by providing an audio signal input-output circuit which receives external audio signals and outputs the audio signal output of a microphone. CONSTITUTION:When a speaker pushes a speaker push button, switch 30 is closed to let lamp 9 come on, and switch 22 is changed over to the terminal 25 side to send the voice of the speaker to respective units in front of other attendees by way of microphone 2, low-frequency amplifier 21, resistance 24, and external connection terminal 5. The voice of another attendee, on the other hand, is oututted from speaker 13 by way of external connection terminals 4 and 5, resistance 24, low- frequency amplifier 27, etc.
