　　Features：

　　300 Watts x2 Power Output: Provided by the TI TPA3255 chip which features an advanced feedback design and proprietary high-speed gate driver error correction. In addition to excellent audio performance, TPA3255 achieves both high power efficiency and very low power stage idle losses below 2.5W.

　　High Efficiency: A significant upgrade from the BT20A amplifier. There're two plug-ins NE5532 Op-Amps can be replaced by MUSES02/OPA26041P/OPA2134PA Op-Amps etc. To create a different sound quality. SNR≥108dB; THD≤0.005%.

　　Upgraded Bluetooth 5.0 connectivity: By pressing and holding the volume control for five seconds, the Bluetooth pair can be cleared. In addition, it has a Bluetooth memory function, so it can be easily paired the next time. It also receives an alert tone.

　　Sound Control: With its unique design, the BT20A Pro amplifier for home audio has a wide range of bass and treble controls. Alternatively, you can turn the treble and bass effects to a middle point to listen to the original sound without effects.
