	“K4 ”Series 4Channels Power amplifier  
	In accordance with the professional HI-FI design, the whole machine is designed with patents; it is safe and firm, concise and artistic. It is used Motorola plastic package expanding output, and the components are matched elaborately, which is meticulous manufacture and complete styles. The output noise is low, the power is large, the trend is width, well arranged, the sound field is wide, the voice is clear, transparent, and the tone is pour, fine and smooth, and low voice is powerful and solid. The electromagnetic compatibility is good, and is shake-proof and throw-proof, whole functional intelligent security, which is applied in all kinds of high level loudspeaker box.
