Bluetooth Amplifier Board with TPA3116D2 Chip,50W+50W Peak Power Output Class D AMP Module for DIY Wireless Speaker (ZK-502C)

Description

① What is the TPA3116D2 chip? TPA3116D2 is a Class D power amplifier IC launched by TI, with very high index parameters. The highest modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1% 

② I hate reading the manual? Please be assured that you do not read the manual! We have added a variety of interface logos on the cool black shell, so that you can see at a glance, even if you do not need a manual, you can connect it correctly.

 ③ How many signal input methods does it have? Bluetooth and AUX input methods! When these two input methods input signals at the same time, the Bluetooth input method is the priority input method. If you want to use AUX, please disconnect the Bluetooth connection. 

④ Warm reminder: The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.
