Audio Amplifier Section | Best Audio Amplifier Circuit. The amplifier section is designed around operational amplifier IC LME49710 (IC 2). Input audio is given to inverting terminal of IC 2 (pin 2) through variable resistor VR 1 and electrolytic capacitor C 4. Variable resistor VR 1 is used to control the level of volume and capacitor C 4 block the DC signal

Amplifier Circuits Introduction to Impedance and Bandwidth Control. Modified Response Curves Previous modules have concentrated on producing a flat frequency response over the required 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
The Simplest Audio Amplifier Circuit Diagram

Connect the circuit diagram as in the one marked with “Amplifier with Gain = 20” and you get 20-fold the signal. If you need exactly 6, you can play a round with the resistance on the input. For splitting the signal, you can use resistors for basic splitting. Google “signal splitter circuit” to see some examples.

The gain of the amplifier is set by these resistors and can be calculated as follows: Gain = (R5/R3) = 22/2.2 kilo ohms = 10 As a result, the high-frequency element of the audio signal is amplified 10 times compared to the input audio signal. The op-amp’s output is drawn from the IC’s pin 6, which is connected to one of the speaker’s wires.
