Tone Control Circuit Diagram. An audio tone control circuit is said to be active if it consists of amplifier. As application of this tone controller circuit it.
Basically there are 2 types of audio tone control circuits. Tone control shown in its most basic form in fig. This is must before audio level controller.
Now you can control the bass treble and volume by rotating three potentiometer on the circuit.
The bass control basically allows only the lower range of the frequency ideally between 10hz and 300hz that means the user can adjust this pot to cut off all. The discussed bass treble tone controller circuit thus effectively performs like a 3 band graphic equalizer circuit allowing the user with distinct 3 way control of the sound frequency. Pre tone control stereo using ne5532. A simple method of achieving this is to place a variable cr network between the voltage amplifier and the power amplifier stages the value of c1 is chosen to pass the higher audio frequencies this has the effect of progressively reducing the higher frequencies as the variable resistor slider is.
