LM1036 Stereo Tone ( Bass, Treble, Volume, Loudness, Balance ) Controller Circuit

The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems.

This stereo tone controller circuit uses mono controller to controlling tone.


  • Wide supply voltage range, 9V to 16V
  • Large volume control range, 75 dB typical
  • Tone control, ±15 dB typical
  • Channel separation, 75 dB typical
  • Low distortion, 0.06% typical for an input level of 0.3Vrms
  • High signal to noise, 80 dB typical for an input level of0.3 Vrms
  • Few external components required

Four control inputs provide control of the bass, treble, balance and volume functions through application of DC voltages from a remote control system or, alternatively, from four potentiometers which may be biased from a zener regulated supply provided on the circuit.

Each tone response is defined by a single capacitor chosen to give the desired characteristic. By changing the values of capacitor connected to tone controlling unit, you can control bass and treble levels. pin 3 and pin 18 of IC are for treble and pin 6 and pin 15 for bass.

    hi there , i’v made this circuit according diagram with 103 & 394 for
    pins: 3; 18; 6 & 15 . but i’m not satisfy because the voice is not prefect .
    i want to change them for better sound ,if not i’ll try for tda .
    wish u success .

    try to make a pcb
    layout, it so simple

  6. cyrus says:

    boom sound its depend upon mounting of capacitor and resistors
