I have digital recordings on the computer and on flash drives. I want to apply them directly to an amplifier. How can I do this?"
The inputs of common audio amplifiers are analog, requiring analog signals. At the output of computers, except for the output to the earphone or speaker, just like on USB sticks we do not have these signals. In digital media, there are memories that must be read bit by bit by an appropriate program that then converts the information into an audio signal. Thus, to read these media and apply the signal to an amplifier, it is necessary to use a digital reading circuit that converts to analog form.
