Tone Control Schematic. The Resistor R5 10k must sitting after the Bass Controller and not by the Treble Controler. This is a inexpensive high fidelity hi-fi tone control circuit designed just with two low cost transistors as the active components.
In simple language Tone Control Circuit is the circuit using which we can control the output of audio device. This is a inexpensive high fidelity hi-fi tone control circuit designed just with two low cost transistors as the active components. This simple tone control circuit is designed based on the famous Baxendall tone control circuitry.
The frequency response is not as good as with using an opamp but it is still acceptable provided you just want a way to boost bass treble and mid frequencies.
In other words it is able to attenuate or boost bass and treble 2-frequency bands. By the Tone Control Circuit is the Resistor R5 10K at the false position. POT R10 serves as the volume controller while POT R11 can be used to adjust the balance. This Hi-Fi tone control circuit can be operated with wide range supply voltage 12V 24V.
