Abstract

PURPOSE:To obtain an excellent attendance feeling by mounting a leftward, a rightward, an upward and a rearward microphone units toward one point in a sperical vessel made of metal, individually amplifying the outputs of therespective microphones to record a sound and driving a four channel speaker. CONSTITUTION:In the metal spherical container 1, the four leftward, rightward, upward and rearward microphone unit 2 are mounted so as to be directed to the one point of a center. The outputs of the respective microphone units 2 are individually amplified by a high gain microamplifier 3, to constitute a four channel acoustic signal and record on a tape. At the time of a reproduction, they are adjusted through an equalizer, a preamplifier, an attenuator and a main amplifier for every channel to drive the leftward, rightward, upward and rearward speakers. Thereby, a harmful noise is removed and an excellent sound field is formed.
