Tinysine TSA7510B
Class D Amplifier Module TPA3221 Bluetooth aptX TWS 2x100W
The TinySine TSA7510B is a Class D amplifier module capable of delivering 2x100W with a high efficiency of 90%. It can therefore be combined with passive speakers in 2, 4 or 8Ω. It also includes a Bluetooth AudioB Plus module, giving it a significant user comfort since you can broadcast your audio files directly from your smartphone or tablet. The Bluetooth chip supports the aptX and aptX Low Latency protocols to improve transmission rate and stability in order to improve the quality of sound reproduction.
The TSA7510B also supports TWS mode. It is possible to combine two TSA7510B modules together to stream audio files to them at the same time.
The module is also versatile as it can be connected to other TinySine add-on modules (sold separately) such as the TSA1000, TSA1010 and TSA1020 volume controllers. An additional line output also allows you to connect a subwoofer to it.
Adjustable gain with DIP switches from 18 to 34dB
Connection diagram
The TSA7510B automatically detects the audio input, with Bluetooth having the highest priority. When Bluetooth is disconnected or not used, the amplifier will use the AUX / Line outputs.
