Audio frequency amplifiers intended for instrument amplification, such as those for guitar and bass may have additional requirements imposed due to the subjective nature of music creation. Before the advent of the solid state rectifier, all audio and instrument amplifiers employed vacuum tube type rectifiers within their power supply circuitry.

5.8.3 Audio frequency amplification The demodulated audio signal is applied through an RC coupling circuit to the first audio frequency amplifier. The resistor R is shown as a variable R and is used as a volume control, while the capacitor blocks DC from getting to the first audio stage and also from interfering with the DC biasing of that stage.

Audio Frequency Amplification. Audio-frequency amplifiers are intended to amplify frequencies (corresponding to the number of air pressure variations that occur per second) in the range that the human ear can hear. Frequency is associated directly with musical pitch, i.e. as pitch goes from low to high, so does the frequency.

THE DESIGN OF LOW-NOISE AUDIO-FREQUENCY AMPLIFIERS considering current ratios, without explicitly referring to the magnitudes of the voltages appearing at the amplifier input terminals. A great deal of confusion has arisen over the rela tion between noise figure and input resistance. It should be clear from Fig. 3 that if an amplifier has a
Amplifiers - Learn About Electronics

Audio frequency amplifiers are used to amplify signals in the range of human hearing, approximately 20Hz to 20kHz, although some Hi-Fi audio amplifiers extend this range up to around 100kHz, whilst other audio amplifiers may restrict the high frequency limit to 15kHz or less. Audio voltage amplifiers are used to amplify the low level signals from microphones, tape …

The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.
