Brief Introduction:
Another new member of Class-D audio  amplifier family comes out – AA-AB32191 which is capable of delivering dual  channel amplification with each channel up to 300W. This amplifier is a  state-of-the-art dual channel Class-D audio amplifier which integrates TI’s  TAS5630 as the driver. High quality and high performance components are used  making this amplifier high-quality amplifier. Powered by 20V to 50V supply, it  can be used in many applications, such as Home Active Speaker, AV Receiver, Mini  Combo System, etc.. It also features short-circuit and thermal protection. In  addition, on-board heat sink and cooling fan ensures excellent heat  dissipation.

Resistance and capacity components of high  quality, including X7R ceramic capacitors, Metallized Polyester (PET) Capacitors and lower ESR  electrolytic capacitors, high performance inductors are  used to gain the perfect timber, finally realize high S/N ratio, low THD+N, wide frequency response range etc.
