Feature

●Applications: This audio digital power amplifier board strengthens low-power audio signals such as radio signals and electric guitars. Power amplifier allows listeners to hear signals. It is the last stage of a typical audio playback chain before sending a signal to the speaker and speaker box.
●Sound Quality: This audio power amplifier module has very good sound quality. No crossover distortion or transition modulation distortion. No need to worry about the internal resistance of the speaker. The right speaker impedance is 4/6/8 ohm, it is very suitable for normal speakers to enter the Bluetooth speaker.
●Multiple Inputs and Outputs: Supports various audio input methods, such as Bluetooth, USB, TF card, and audio input. Support playback format: MP3, WMA, WAV, FLAC.
●【Power and Voltage】TPA3116 Stereo Dual Channels: 50W + 50W output. TPA3116 Bass: 100W Subwoofer Output Wide input voltage range 12V - 26V DC.
●[Applicable Power Supply] We recommend using DC 24V, 5A or higher power supply (lack power current, and the volume is loud, the sound will disconnect). If the power of the speaker is so big, you can use 24V 3A power supply.
