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 amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the TEA2025 datasheet for more information on that) On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both the left and right channels on one potentiometer.

An integral voltage-controlled amplifier (VCA) provides up to 60 dB of gain in the signal path with approximately 30 kHz bandwidth. Additional gain if required is provided by an input buffer/ microphone input op amp circuit that can be set anywhere from 0dB to 20 dB, for a total signal path gain of up to 80 dB.
5 Simple Preamplifier Circuits Explained - Homemade ...

The circuit is a simple two transistor pre-amplifier using a feedback loop for enhancing the amplification. Any music as we know is in the form of a consistently varying frequency, therefore when such a varying input is applied across the indicated C1 end terminals, the same is delivered across the base T1 and ground.
