※ Using original TPA3116

※ The main circuit of the electrolytic capacitor signal adopts Taiwan, and the main filter capacitor adopts the special electrolytic capacitor of Japan Chemical Co., Ltd. with a capacity of 4×3300UF, which ensures a strong and continuous power support.

※ The resistor adopts 5-ring metal resistor, and the main circuit adopts the chip resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.

※ The PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. PCB quality.

※ Using fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers!

※ The red-gray ring high-current audio special inductor is used to ensure the sound is crisp and powerful.

※ The switching signal element adopts Hongfa relay with good quality

※ The way to connect to Bluetooth is the same as that of ordinary devices! Search device (YJHIF) - point (YJHIFI) connect device - play music

※ Input methods include bluetooth and analog input. When the two methods are input at the same time, the bluetooth input takes priority. When analog input is required, please turn off the bluetooth function of the mobile phone before switching.
