FK2250
﹛﹛﹛
Adopt unique symmetric floating design, distortion of PA can offset each other, achieving the result of reducing distortion and sound more accurate.
Add screening can around amplifier circuit and shielding ring for transformer, to reach the effect of clearer sound and smaller noise.
Cooling system adopts independent closed duct, to get better heat dissipation and dustproof effect.
Have perfect protection system, with starting up buffer prior, delay connection loudspeaker, amplitude limit, output DC protection, overheating protection, over current protection and short circuit protection, etc.
