TOPPING PA3s Power Amplifier MA12070 2 Class D Full Balance Single End AMP 80W 2 RCA TRS Power Amplifier (Silver)

------------------------------------------------------------------------------------------------------------------ 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. (This product does not include a transformer.) Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer. ------------------------------------------------------------------------------------------------------------------ 【2xMA12070 Full Balanced Class D Amplifier】: Each channel of PA3 uses one MA12070 class D power amplifier chip. This allows you to separate layouts to improve performance and reduce crosstalk. Power is shared between the two chips and heat dissipation is also halved for each chip, improving reliability and extending product usage time. [High Power]: PA3 can output 80Wx2 at 4 ohm load, 10% THD+N. At a higher standard of 1% THD + N, the output power will be 65Wx2 at 4 ohm load. The output power is enough to drive bookshelf speakers and some floor speakers. 【Balanced + Single-ended Input】: PA3 provides TRS balanced input and RCA single-ended input. Using balanced inputs eliminates potential ground loop issues and provides clean, hum-free audio. [With the help of DAC, the functionality is greatly expanded]: PA3 can be used with DAC to expand the categories of digital inputs. When used with DAC + HPA, more comprehensive functionality can be achieved. 【Appropriate Distortion】: PA3's lowest THD+N is in the output 10-20W range, which happens to be the power range commonly used for listening to music. Everything is in good condition. PA3s power amplifier specifications: SE IN： THD+N @ 1kHz (A-wt):
