Freude FX-4 Class A/B 4-Channel Amplifier
SKU:FX-4
Class AB 4 Channels Amplifier
Class AB 4 Channels Amplifier ■ High bias voltage ensures excellent sound reproduction; advanced heat dissipation structure solves the heat generation problem caused by high power output. ■ The unique amplification circuit ensures consistent temperature rise at the output level, high stability, and good channel consistency. ■ The machine adopts a Hi-End grade single differential circuit design, and the tuned and matched feedback circuit allows the machine to work in a perfect high driving force state. ■ The machine design includes multiple auxiliary protection circuits, so you can rest assured. ■ RCA adopts a more unique design and packaging, thereby effectively ensuring the stability of the audio source input. ■ It has an independent symmetric power supply design, effectively ensuring the consistency of the front and rear sound fields and the current response speed under large dynamics. ■ All capacitors in the machine use a high ripple series, which extends the machine's lifespan. ■ The PCB is designed according to the principle of heat guidance, reasonably avoiding the common problem of local overheating. ■ The entire machine's PCB circuit design is standardized, with reasonable grounding and minimal circuit noise; and it has an ultra-low distortion rate.
