FIELD: audio signal reproducing devices. SUBSTANCE: device has high-frequency filter for passing only high- frequency component of reproduction signal. Clipper functions to clip signal between predetermined levels incorporating highest high- frequency noise components. The latter are present in reproduction signal processed by high-frequency filter. In adder clipped signal is superimposed on reproduced signal to separate high-frequency signal. Device may incorporate nonlinear amplifier for amplifying reproduction signal processed by high-frequency filter with preset gain without phase shift between high-frequency filter and clipper. Clipper has at least two diodes. Cathode of first diode and anode of second one are connected to input contact and respective anode and cathode, to output contact. Capacitor and resistor function to connect output contact in series with ground. EFFECT: improved design. 5 cl, 2 dwg
