I have one Sony 5.1 sound system but its 7-segment LED display is not working properly because the numbers (volume level) are not showing up completely and all the segments don't light up. Sometimes, the whole display shows nothing at all.
I need to know whether the LED driver IC (PTC 6955) is...
I got this chinese xy-p40w amplifier powered up by 20v after step up and using it for 5.5 ohms speakers the issue is that its truns it self off and back onn when there is bass, what could be the problem if anyone can help
My KRK 10s subwoofer has a problem where at a certain volume/power draw it will make a small pop and cutout completely. Once the volume lowers down the speaker will com back and continue to work as usual as long as it's below the volume it cuts out at. This will consistently happen at (I think)...
Hello Dear Friends, I need to know dos and do not about my idea. My knowledge with electronics is near Zero but I am doing at DIY projects.
I have a software that generates healing frequencies from 20Hz to 20Khz out of my audio interface, now I need to connect the output signal to tens...

This home audio system started making noise even when no input signal present, as long as it is switched on. It is not about ground issue or isolating the noise. It is coming from its amplifier circuit. Also its LED is not working and user interface went off while trying to find the problem. It...
Hello Hive Mind!
I have the Denon PMA-350se power Amplifier, which has some distortion on the LH channel only. I have been playing with Sine waves and probing with the Oscillsope, but am limited in what I can do. A service manual with circuit diagrams can be found: edit: Thank you for pointing...
Hi,
Im looking into designing a 7.1 audio amplifier, and i was wondering what the best budget vs quality audio amplifier IC would be. I'm looking for around about 30w of power and I plan to use seperate ICs for each stereo group unless there is a specific 7.1 ic that fits this purpose.
TIA.
Hello guys!
I found this board with 25W + 25W audio output and I found that this thing has a switch controller for music and volume. But I couldn't find how to solder them. Is there anyone who used this board? Could you please help me with a diagram?
After a massive crash on LM386 I moved on to TDA7052. This is a very good IC so far. I want to make sound boxes and sell them. That is why I want to know more info than datasheet if available. I have some questions though:
1. How to secure the connection to reduce noise?
2. How to protect the IC...
Are this Chinese made SMPS power supply compatible with LA 4440 IC? I mean that can I use it for any audio amplifier or Bluetooth mp3 FM module? Please tell me! If I can use it, then please tell me how I can do it?
