The power supply is a 12V, laptop supply.

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

Stephan on March 13, at 1: I need to break-in my new subs. This is actually explained in the article. Datasheer on November 23, at 6: I took a lot of time to see Reply.

As a request, would you not like to attempt a oscilloscope using an arduino uno with the same clear instructions Thanks again Roy. I also am confused by the pf cap C6.

Can you share the PCB layout in this article? Thanks to circuit basics. I took a lot of time to see. I agree to let Circuit Basics store my personal information so they can email me the file I requested, and agree to the Privacy Policy Email me new tutorials and very occasional promotional stuff: Consent to store personal information: If you were to put this in a copper layout what would it look like.


Could you tell me more about the theory here? Do you need a picture of the circuit? I am about to try the same thing stereo. What was the impedance of the speaker you used? Venkatagireesh on October 27, at The chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. Disregard, I found the issue. Nuwan madusanka on October 13, at 1: There should be three caps connecting the positive rail to ground.

Sipan Hadji on February 13, at 9: And what are the voltages of capacitor that you used? Hoping to be of some help. I tested it and it worked! Yes it will Reply. So i just tried building the second circuit diagram and the sound is just awful I did build it on a bread board how much better can I expect it if I build it on vero boar with short wires and such?

Is there any advantage to supplying pm386n LM with 9v instead of something closer to the minimum 4v it requires? Onno on December 1, at 1: Hi, Is this amplifier have enough power to fill a 4m x 4m room? No you dont need to learn c languageā€¦. Oh dztasheet, i was datashet to make the minimal lm aduio amplifier. Could you post a link to the video?

You can use another value for all of the capacitors, dataxheet they should around the same value Reply. Igor on December 1, at 9: Anything 16V and over will work fine with a 9V supply Reply.

Segway on January 31, at May I know what are the voltage of all the capacitor used? I just want to ask if you can datsaheet me a copy of the schematics because im not used to bread boards which is I am really ashamed of, LOL.

Julio on July datashest, at 9: Florence on October 24, at 6: But yet I have a few questions D: Hoverboards UK on May 18, at 6: Dear sir Resenltly ln386n purchased the Arduino Duo board for INR but when i conected to my laptop asked me to download soft ware and i down loaded. For that you would need to build a tda or tda amp. Sir, what kind of speaker we should use. Jefferson Yagdulas on March 3, at 3: Hi, Is it possible to get boost mid and boost trebles controls putting more 0.
