About the circuit.

Here is the circuit of a stereo preamplifier circuit with built in tone control facility.A very useful circuit using versatile tone control IC TDA 1524 from Phillips.

The circuit is designed as per the data sheet as an effective stereo-tone & volume control for car stereos , TV sets or  any sort of stereo amplifier circuit you want.The circuit  includes provisions like bass control, treble control , volume control with inbuilt contour or linear mode option (can be switched in betwwen) and balance. All these functions provided can be controlled by DC  voltages or by  linear potentiometers.

Tips .

  1. R1 ,R2 ,R3 andR4  can be used for controlling volume,balance ,treble and bass respectively.
  2. If SPDT  switch S1 is in position 1 ,the circuit works in contour mode and  in position 2 the circuit works in linear mode.
  3. The circuit can be powered from 7.5  to 12 V DC supply.  Do not give more than12V.
