Giới thiệu Bảng Mạch Khuếch Đại Âm Thanh Kỹ Thuật Số Tpa3221 100w + 100w tại Lotte Market

TPA3221 is a high-power class D amplifier that can achieve high efficiency in full power, idle and standby states. The device uses closed-loop feedback with a bandwidth of up to 100kHz to provide low distortion in the audio frequency band and achieve excellent quality. The device operates with AD or low idle current HEAD (high-efficiency AD e) ulation and can provide 2 x 105W power for a 4 ohm load or 1 x 208W power for a 2 ohm load.
The main filter electrolytic adopts the imported famous brand Erkang with a capacity of 2200UF/35V*4 to ensure strong and continuous power support.
High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
Adopt special magnetic ring inductor for audio to ensure the sound is clear and powerful.
