①All interfaces use screw terminals, so that DIY players can easily connect without an electric soldering iron.
②In order for the power amplifier chip to have a longer working life and to maximize the performance of the TEA2025B, we installed a large heat sink for it. If the heat sink is not installed, the power amplifier chip will heat up when it works for a long time. When the heat reaches a certain temperature, the output sound will be distorted; when the heat is very serious, the power amplifier chip will burn out!
③ Referring to the official standard circuit design of TEA2025B, increase the total volume adjustment knob, which is convenient for users to adjust the volume to achieve the best effect! The TEA2025B chip has the characteristics of sweet and pleasant silver tone, excellent performance and reliable operation. It is deeply loved by audiophiles. Many big brand audio manufacturers also use this power amplifier integrated chip, such as Edifier's R101V, R101T06, modern CJC -112 and other models use the TEA2025B power amplifier integration!
