TPA3116 Bluetooth 4.0 Digital Amplifier Board 2.1 Channel High-power Subwoofer
British CSR8630 4.0 HIFI Bluetooth receiver chip + TPA3116 digital amplifier chip
support analog signal input and Bluetooth signal input， Bluetooth input priority.
The amplifier board with two TPA3116D2 digital amplifier chip as the core，One do a left and right channel power amplifier，and the other bridge driver subwoofer， with small size， high efficiency， high power characteristics. Regardless of the cost of materials， capacitors Philip， Thomson， ruby. Taiwan-quality potentiometers sealed， original TPA3116D2 chip， SMD chip devices， and so on. Board circuit is simple， reliable work. Operating voltage 12V-25V. Left and right channel output 50WX2， subwoofer output 100W， efficiency can reach above 90%， you can use switching power supply laptop is also very suitable for battery-powered devices， such as motorcycles， cars， electric cars， and so on. Compact board， use and installation are very flexible and convenient. All use genuine components using devices capable of long-term stability.
the potentiometers from left to right: is Stereo volume \\ subwoofer volume and total volume
Special Note: The front panel switch is used to cut output， not cut off the power. Therefore， the power light is always on， not surprising. Because for this circuit，the quiescent current is very small when There is no output， Internal circuit protection circuit has been perfect， no other access.
Operating voltage: 12V-25V (recommended to use high-quality switching power supply)
Features:
1.This is assembled Board and tested well.(we recommend use the Shield wire and metal chassis)
2.Panel in the middle of the gap can be used to hold the terminal.
3.This board is very suitable for household and car amplifier
4.With expensive red ring inductance， not the small power TPA3116 can be compared
5.Excluding external power supply， you can use the notebook power
6.New professional high-power digital 2.1 amplifier board 50W+50W+100W， NE5532 OP-amp.
