Power Amplifier 400W Audio Circuit 2SC2922 2SA1216

The power amplifier is indeed very simple, but no doubt the sound quality produced. Mid-low sound output character is very suitable for indoor or outdoor. For Outdoor try using Transformer 20A 45Vct, tr final 5 sets/channel using Sanken 2SC2922 / 2SA1216, which can produce up to 400W - 800W stereo power output. To generate maximum output power you should use high-quality components. Below the circuit diagram of mono power amplifier 400W using the Sanken Final transistor.
