YMX-809 Bluetooth5.0 Amplifier Board 5V 2.1 Channel Digital Amplifier Amplifier Board Audio Module Board

YMX-809 Bluetooth5.0 Amplifier Board 5V 2.1 Channel Digital Amplifier Amplifier Board Audio Module Board Popis

The YMX-809BT uses 5.0 with 5V 3A power supply. Through secondary development of peripheral hardware, the maximum power can be configured to 20W [10W for the subwoofer + 10W for the amplifier (5W*2)]. Therefore, this amplifier board has strict requirements for the power supply and speakers, especially the subwoofer.
Power Supply: voltage 5V (4.8-5V), current must be 2.5A-3A or higher; (If powered from USB, the power supply itself must have a power of 3A or higher, and the power cord must also be able to handle this large current. Often, some power supplies have the current but the cord cannot handle it, resulting in the same problem.
Secondly, the power bank must be an original, genuine product from the manufacturer. Counterfeit power banks not only have insufficient current and unstable constant current, but their instantaneous current is also insufficient (unable to power the speaker or causing distortion), which can easily damage the board. Please be careful!!)
It's important to note that if the power supply and speaker configuration are inadequate, or if the audio source level is insufficient, the power output will be insufficient. For a more immersive sound experience, please visit the factory to assess the sound quality.

Selection Requirements:

Power Supply Requirements: voltage 4.8-5V, voltage not exceeding 5V; current 3A or higher.
