Simply put, the purpose of an audio amplifier is to convert a low-power audio signal into a high-power audio signal. The high-power signal is large enough to drive a speaker sufficiently loud. In order to do that, an amp uses one or more elements which are controlled by the low-power signal to generate a large-power signal.

audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency dependent. This can be achieved by modifying either the response of one or more of the amplifier stages, or the response of a negative feedback path.

10. R6/R5 defines the ac gain of the amplifier 11. C4 enables DC gain = 1 (full negative DC feedback from output to "input": T1 emitter ac voltage ≈ T1 basis ac voltage). 12. 1/(2πR5C4) creates one of the lower -3dB frequency limits (48Hz) of the amplifier gain. 1/(2πR LS *C2) establishes one more lower frequency limit (4.5Hz)

Amplifiers are used to increase the amplitude of a voltage or current, or to increase the amount of power available usually from an AC signal. Whatever the task, there are three categories of amplifier that relate to the properties of their output; 1. Voltage amplifiers. 2. Current amplifiers. 3. Power amplifiers.
