2*300W 4Ohm Audio Amplifier Board TAS5630B HPAB5-300 Fever Large Power Subwoofer

2*300W 4Ohm Audio Amplifier Board TAS5630B HPAB5-300 Fever Large Power Subwoofer 

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 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.
