DEVICE FOR INCREASING THE OUTPUT POWER OF A LOW VOLTAGE POWERED RADIO APPARATUS, FOR EXAMPLE OF THE AUTORADIO TYPE

摘要

P THIS DEVICE IS INTENDED TO INCREASE THE OUTPUT POWER OF A LOW VOLTAGE POWERED A2 AMPLIFIER AND CONNECTED TO A STANDARD IMPEDANCE RL SPEAKER AND POWERED WITH A VB VOLTAGE WHICH, IN THE PRESENCE OF A SIGNAL AUDIO, IS COMPOSED OF THE CONTINUOUS VS VOLTAGE OF THE APPLIANCE AND A SUPERIORED VARIABLE VOLTAGE, PROPORTIONAL TO THE AUDIO SIGNAL THAT ENTERS THE AMPLIFIER A2. In this way, we obtain a great dynamic of the signal coming out of the amplifier A2 and sent to the loudspeaker RL. / P
