The maximum output power of a single channel is as high as 180 W, and it can reach 400 W in bridge mode, which is enough to easily drive a high-performance subwoofer. It can be said that this device alone can significantly improve the resolution of the host sound source, solve the problem of insufficient signal quality, and at the same time fully stimulate the potential of each speaker, so that the sound can glow with richer texture and vitality, and truly achieve “One machine can do all things, enjoy Hi-Fi instantly”.
