Just wondering will this circuit still work if I increased the number of speaker to speakers? Circuit Basics on November 19, at 7: It is just the added bass control that I am having a challenge with….

Is it a mistake, or should there be a total of three caps connecting the positive rail to ground, of which two caps are 0. Florence on October 24, at 6: Here C2 and Datashete are in series.

Where is the schmetic diagram?

So i just tried building the second circuit diagram and the sound is just awful I did build it on dahasheet bread board how datwsheet better can I expect datasheeet if I build it on vero boar with short wires and such? Segway on January 31, at Yes, you can use a 3. Arslan on April 3, at Thank you for the article and all the circuits. But I have a question about the gain of Lm38n-1 can use another value for all of the capacitors, but they should around the same value Reply. For that you would need to build a tda or tda amp.

I just updated the images to show the positive side of the cap leading to pin 5. Then a 1K resistor from pin 3 of the LM to ground.

After doing so i decided to make the other channel stereo soundand replicated the circuit on the other side of the board. Rajesh on September 22, at 4: It works great now! Hi Sanjeev, double check to make sure everything is connected properly, and the polarity of the electrolytic capacitors dataeheet correct… Reply. Sir I have 4 ohm 2speakers so what amplifier I should use Reply. I built a few things with this chip utilising the differential input.

I agree to let Circuit Basics store ,m386n-1 personal information so they can email me the file I requested, and agree to the Privacy Policy. You really did a great job here…I actually wanted to construct an external amplifier to connect to my Pc and Phone as we know how lousy and low the Audio output are.

Thank you for sharing! RickS on July 21, at I usually just double the voltage for the circuit…. For that I think you would be better of building a dedicated subwoofer amplifier, or using a tone control circuit.

Novice on Dafasheet 26, at 8: Hoverboards UK on May 18, at 6: Gert on September 25, at 8: My question is, how would the audio input be wired? I would like to add the other channel stereo by duplicating all relevant components. NiCk nick on December 8, at 4: That amp was designed for car audio use, so it dstasheet be a better choice for you project… http: Would it be okay to use your LM audio amplifier with bass boost figure as a reference design in the paper?


For example, you can connect the grounds for the power supply, input, and output directly to the ground pin pin 4 of the LM like this:. As a tester for a particular system.

Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM386

No you dont need to learn c language…. Do i need to learn C programme.

Dan L on November 24, at 1: I used an 8 ohm speaker, but anything from 4 to 16 ohms will work. Victor Faucheret on April 24, at 5: It drives a pair of 8Ohm Onkyo home lm3386n-1 speakers with room filling sound.

R D Biggs on November 20, at 9: I tried both options while building this. Circuit Basics on March 8, at Some how I miss old dos, in some ways it was less complicated back then. I am having a problem with the extended bass circuit.
