12V Amplifier Board, 15W+15W 2.0 Dual Channel Audio Amplifier Board PAM8620 DC 8-26V 24V Digital Stereo Amp Module Class D Mini Power Amplify Circuit for Sound System Speaker DIY

Parameters: The audio amplifier board operates on a working voltage of DC 8-26V and can be powered by 12V or 24V; the output power is 15W stereo (24V 8ohm) / 10W stereo (12V 8 ohm), and if a 4 ohm or 2 ohm speaker is connected, the power will be automatically limited to 15W.
Artificial Material: This newly designed stereo amplifier module is made of a noble black immersion gold circuit board, PAM8620 chip, imported KEMET speaker capacitor, and a large-capacity filter capacitor for channels. In addition, we customized black copper terminal blocks and gold-plated audio input terminal blocks for this new amplifier module.
High Performance: The class D power amp module offers high efficiency of over 90%, general harmonic distortion noise is less than 0.2 %, low quiescent current, and noise suppression.
Safe Protection: The 2 channel amp board is designed with input reverse connection protection, short circuit protection, heat protection, overcurrent protection, overvoltage protection, and undervoltage protection; moreover, EMI is allowed to pass.
Additional Function: It is possible to connect an external mute function (MUTE: High level mute, factory default low level); possible to add an external
Shutdown (SD: the chip will be Shutdown at low electricity level, factory defaults high electricity level
