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.
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?
