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

Only negative thing is when I connect the bass boost that there is a lot of dB loss. Thank you for the article and all the circuits. Thanks for easy homemade circuts i love this siteReply. Check out this article for more info: Thank you this helps so much, im wondering if there was any way i can minimize the input voltage down to a 3.

May I know what are the voltage of all ratasheet capacitor used? Siraaj on April 14, at 9: Thempleton Aart on October 12, at 4: Do you mean the pF capacitor?

Is this normal or is something else going on? The LM cannot amplify more than the input voltage, if you have a 1V input signal the output will max out at 5V. Excellent tutorial I managed to make the first two today and will work on the final versions next. I am working on a research paper for my senior design class at UCF.


The minimum voltage rating is 4V, so it might not work. Sir you can use a 3. When I google for RC low pass filter the load is connected between the resistor and capacitor. It is just the added bass control that I am having a challenge with….

Mine was working right away and really surprised at the clarity. VAneza ybanez on November 25, at 6: Will this one do??? Official Hoverboards on May 18, at 7: The bass boost and the gain pots are not connected to ground.

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

Hi, Is this amplifier have enough power to fill a 4m x 4m room? Though its better if you do…… But if you search in Google with the name of the project you will find the script…… Just copy and paste it.

Adinol on December 23, at 7: In other words, connect pin 3 of the IC to ground with a capacitor and a resistor in series? Hi Sunil, you can use another value, like a 0. Do i spend money for that. Could you post a link to the video? Hi Alex, this amp works great for headphones… Since the diagrams in the post are mono amps, all you need to do is build two amps, one for the right eatasheet and one for the left ddatasheet.

Alex on August 10, at BTW the extended second circuit was great and worked the first time I fired it up. Simon Tay on August 28, at 8: The idea is to lm386nn-1 another capacitor as close as possible to pins 4 and 6 to maximize the decoupling.

Babu Ramalingham on July daasheet, at Aravind on March 31, at I used the LM and looking to replace it for the LM
