Hello Friends, I made a flat frequency Stereo amplifier in this post, which can deliver up to 68W output per channel at 4Ω. For this amplifier, I use LM3886 IC. This IC is specially designed for active studio monitors, for its low noise distortion. And this IC is best for singers. This IC has built-in short circuit protection and over-voltage protection, so it is more expensive than others.
