Here are the key features and components of this amplifier module:

TPA3116D2 Amplifier Chip: This module is based on the TPA3116D2 audio amplifier chip, which is known for its efficiency and high-quality audio output. It supports both stereo (2.0) and 2.1 channel audio configurations.

Output Power: The module offers a total output power of 2x 50 watts for the two satellite channels (left and right speakers) and 1x 100 watts for the subwoofer channel. This provides a powerful audio amplification solution for a variety of speaker setups.

2.1 Channel Configuration: The module is specifically designed for 2.1 channel audio systems, making it suitable for multimedia speakers, home theater systems, and other applications where you want to reproduce low-frequency bass sounds through a dedicated subwoofer.

Input Options: It typically includes a variety of input options, such as stereo analog RCA inputs and possibly a 3.5mm audio input jack. This allows you to connect different audio sources to the amplifier, such as smartphones, computers, TVs, and audio players.

Bass/Treble Control: Some versions of this module may include onboard bass and treble control potentiometers, which allow you to adjust the tone characteristics of the audio output to your preferences.

Power Supply: The module typically operates on a DC power supply in the range of 12-24 volts. You need to provide the appropriate voltage and current to power the amplifier effectively.

Speaker Outputs: It has terminals for connecting the left and right satellite speakers and the subwoofer. Ensure proper speaker polarity when making these connections.

Heat Sink: To dissipate heat generated during operation, many of these modules have a built-in heat sink. Adequate cooling is important to prevent overheating and maintain the amplifier's performance.
