As a member of JAB(Audio Amplifier Boards designed for Jukecase) series, JAB2 offers the wireless solutions with Bluetooth module integrated and can be powered by lithium batteries directly. It is a stereo Class D audio amplifier board with a Texas Instruments TPA3118 chip to achieve high efficiency. Each channel is capable of delivering outputting nominal power simultaneously and continuously. The module dissipates only 0.72W with no signal when in ON mode (around 0.07W when in stand-by mode). Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Over current protection and over temperature protection are included to extend the longevity of the amplifier board. All these features make it a good choice for portable Bluetooth speakers.

Hello. Is it possible to use it with digital potentiometer AA-AA11117?

Hello, Kirill. Thank you for your interest in our products. The JAB2-230 cannot be used with AA-AA11117. If you want to adjust the volume of JAB2-230, there is a VOLUME CONTROL CABLE (POTENTIOMETER INCLUDED) inside the functional cables package (AA-JA11114). Here is the link for your reference: http://store.sure-electronics.com/product/AA-JA11114
