Boomer audio power amplitiers were designed specifically to provideconditions.

Here are some more suggestions: I was wondering why that was there, but I just assumed it was a separate application entirely because of the name!

Yeah, it is pretty good, right? But using the values you used should still give you sound, so there must be something else wrong. It was always something that made me hesitate. No abstract text available Text: I just want to know what is input and output there before potentiometer?

Try switching the inputs and see if this gives you an output on the other channel. Each channel needs 3 pins. This amplifier is great to use together with some speakers to get sound on your desktop computer. I challenge you to figure it out from the datasheet: Are the potentiometers needs to be a Dual Potentiometer 6 pins or can I use 3 pin potentiometer? If you have access to an oscilliscope http: Hi, this could be because there are satasheet inputs on fatasheet channel.

If the sound is very low, you can try to increase the volume of your input device. Your email address will not be published. Home About Blog Contact. Nice and useful post. Yes, 25V should be fine I think. Hi, Yes they are all connected. Oyvind, I manage to make my amp work but the problem i am facing now is the output volume is too low ,can you please help me?


Hey, I think it will become a bit hot yes. Boomer audio power amplifiers are designed specifically to provide highthe Audio Power Amplifier Design section. Clearly I need to learn how to read a spec sheet.

Try a aluminum foil shield to check for external signals that show up as noise. Hi, The input does no go to the speaker. Check the sound level of your music source. Pls help me with the schematic or circuit. And yes, single-sided pcb works fine. If I want to make it Mono, I ignore one of the inputs? Check for oscillations in your component layout etc. But if you want more power, check the datasheet for how to connect the outputs in mono-setting.

Hi Andy, If the sound is very low, you can try to increase the volume of your input device. Boomer audio power amplifiers are designed specifically to provide high quality output power, ground plane, and finally, surrounding air. On the input side, you should use a dual potentiometer. Trackbacks […] TEA — 2. How much voltage rating should have uf capacitor for this circuit.


Please may know what could the course. FYI, ive lost 4 radios in 3 months through crime and im done buying new radios.

Boomer audio power amplifiers are designed specifically to provide high quality output powerfinally, surrounding air. And higher Watt-rating of the speaker just means it can handle more power.

Im only using my phone as the music player. Check the dahasheet stage for bad solder joints can act as diodes hence radio noise. Hope you can help Thank you. There could be noise in the incoming signal.

The design I created was double-sided. And one lm486d thingi think i should add, I am using USB power supply. I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer.

The Simplest Amplifier Circuit Diagram

I have purchased W sterio amplifier with USB and mic-2 kit i want to understand bass treble and volume wiring in 6-pin pot. If you love building things with electronics or would love tocheck out Ohmify. Also, I do not seem l4863d be able to make the LM specs give me hints on how to do it. Thanks for your effort.
