AVT1670 A

The tone controller is a system that allows you to match the sound to your preferences, the properties of the amplifier, the speaker system or the acoustic features of the listening room. The presented layout is easy to make and at the same time quite versatile. It was developed based on the integrated circuit LM1036, which contains electrically controlled reinforcement pies. This guarantees high parameters of the audio track.

The device is especially recommended for electronics constructing audio equipment themselves

Selected parameters:
