FIELD: electroacoustics. SUBSTANCE: stereophonic device for sound reconstruction has two-channel source of stereophonic LF signal with two outputs, each of them being connected to proper diffusion loudspeaker through channel terminal amplifier. Each terminal amplifier is manufactured on base on integrated microcircuit mounted with the aid of threaded elements on interwindow jumper of diffuser holder of loudspeaker. Heat sink in the form of package of plates which ends are bent at different angles to diffuser holder is installed between diffuser holder and integrated microcircuit. EFFECT: facilitated manufacture, enhanced reliability. 2 cl, 3 dwg
