Introduction to LA 4440

This circuit Consist with two LA 4440 ICs. You may know that LA 4440 is stereo type IC. Although in this circuit LA 4440 used as Mono type two amplifiers. Each output out 20W and both output out 40W. This known as Bridge method. One channel of the amplifier has inbuilt Microphone pre-amplifier. So, you can connect microphone directly to amp without using Microphone pre-amp. Also, you no need to use speaker pre-amplifier. Even speaker pre-amplifier come with the main circuit. This circuit best for everyone, who like with classical electronic technologies, Beginners and students. This one is very old circuit. You can try the old day’s technology and get the classical experience.
