Build a compact, high-power audio system with this 3 Channel Digital Subwoofer Amplifier Board, designed for DIY speakers, home audio projects, custom sound systems and other electronics applications. The board uses a TPA3116D2-compatible Class-D amplifier design and provides separate left, right and subwoofer outputs for a 2.1-channel audio setup.
With a 12–24V DC supply, the board is suitable for projects where you need a higher-power audio output without using a large traditional amplifier. It provides two 50W channels for the left and right speakers and a dedicated 100W subwoofer channel, with support for 4–8Ω speaker loads. Onboard volume adjustment makes it convenient to control the audio level during operation.
The Class-D design offers efficient amplification with comparatively low heat generation, making the board practical for compact speaker builds and DIY audio projects. Audio can be supplied from sources such as a Bluetooth receiver, mobile device, computer or other compatible audio source through the board's audio input.

1. What is the 2.1 Channel Digital Subwoofer Amplifier Board?
The 2.1 Channel Digital Subwoofer Amplifier Board is a device that is used to amplify the audio signal which comes as an output from various low-powered devices. Like Mobile phones, laptops, Bluetooth Receivers or even microcontrollers.
2. How to use this Digital Subwoofer Amplifier Board?
The 2.1 Channel Digital Subwoofer Amplifier Board needs a power supply rated at 12-24 Volts and 3 amperes or more. The audio input signal for amplification is given using a 3.5 mm jack or by using the 3 pin header. The amplified output is taken through 3 channels as Left, Right, and Subwoofer. On each channel speakers are connected. The volume of the output can be varied by varying the potentiometers present onboard.
3. Can the Digital Subwoofer Amplifier Board play audio through bluetooth? And what is its speaker rating?
The 2.1 Channel Digital Amplifier Board can be connected to a Bluetooth audio receiver module. The output from the Bluetooth audio receiver is given to the Amplifier board as an input using a 3.5mm audio cable. It can drive 4-8 ohms speakers at 50 watts on the Left & Right channels and 100 watts on the Subwoofer channel.
It's good and excellent at its price range ad works correctly. But the thing confusing in this is that the pins markings I got confused which pin is shutdown and which pin is gpio... It's just written x and e . Soo it's kinda confusing but it a good product from what I have tested
