Stereo Amplifier with TDA1524

The circuit is designed as an active volume and tone corrector for radio receivers, television and audio equipment stationary.

It includes functions for bass and treble correction, volume control with built-in contour (can be turned off) and stereo balance.

All these functions can be controlled by DC voltage or by linear potentiometers.

Features: some external components required, low noise, bass can be accentuated with a double-pole low-pass filter, wide range of supply voltage.

Characteristics:

? Stereo control Bass - High - Volume - Balance

? Low control ± 17dB at 40 Hz

? High tuning ± 15 dB at 16KHz

? Volume control -80… + 21.5dB

? 60dB channel separation

Preamplifier circuit is TDA1524 from the company Philips. His involvement This circuit can with a minimum of external components to change the volume, balance, treble and bass. Its advantage is that all settings adjustment is performed by changing the voltage on the corresponding pins of the circuit and that for both channels at the same time.

Note: I am not the original author of this circuit, I just drew it.
