ABSTRACT:
A device for increasing the power output of a low-tension operated amplifier which is connected to a standard impedance loudspeaker and is powered at a voltage level which, in the presence of an audio signal, consists of the DC operating voltage for the set and an overlapping variable voltage which is proportional to the audio signal input to the amplifier.
Thus, a high dynamic range is afforded for the output signal from the amplifer directed to the loudspeaker.
