2.1 Hi-Fi Class D Audio Amplifier Board 2 x 15W + 30W 10-18 VDC
A handy audio amplifier board with big power in a small package. Delivering 2x15 watts plus 30 watts into a mono channel, this 2.1 board makes it easy to add the bass you need to your next powered speaker project. Use it in desktop multimedia powered speakers or cool boom box applications. The tiny size makes implementation limitless and the easy-to-use 12 VDC power requirement makes it a great addition to any mobile audio project.
These boards are pre-tested and pre-assembled, which makes your project easy to complete. The on-board jacks, potentiometer, and screw terminals mean you can get this board powered up and playing music in minutes. Just connect your power source using a 2.1 x 5.5 mm DC power plug, a 3.5 mm stereo audio source, and run speaker wire from the six screw terminals to you speakers and you are done.
There is an optional 2-pin connector for adding a standby feature, and a 3-pin connector with included jumper for regulating the bass volume (wiring harnesses not included). Add a 50k potentiometer (sold separately) to the 3-pin terminal to control the subwoofer channel's volume separately from the master volume control. When the jumper is placed between the middle and right pins, the subwoofer channel is controlled by the master volume. And when the jumper is placed between the middle and left pins, the subwoofer channel is shut off.
