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.
Features
- 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
NOTE:
- VR1 = BASS CONTROLLER
- VR2 = VOLUME CONTROLLER
- VR3 = BALANCE CONTROLLER
- VR4 = TREBLE CONTROLLER
- S1 = LOUDNESS SWITCH

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.
