PHD.79-089 11.4.80 " ": "Circuit arrangement for eliminating turn-on and turn-off clicks in an amplifier". The circuit arrangement in accordance with the invention comprises an RC-element, to which the same direct voltage is applied as the amplifier. When the direct voltage is switched on or off the capacitor is either charged or discharged, the resulting oppositely directed voltages being applied to the anti-parallel base-emitter junctions of two transistors, whose collectors are interconnected. The collector voltage of said transistors serves for controlling a semiconductor switch included in the audio frequency branch.
