DollaTek 12V Amplifier Board, PAM8620 Digital Stereo Amp Module 15W+15W 2.0 Dual Channel Class D 8-26V 24V Immersion Power Circuit Mini Amplify

Parameters: audio amplifier module working voltage is DC 8-26V, can be powered by 12V, 24V; output power is 15W stereo (24V 8ohm)/ 10W stereo (12V 8 ohm), if connect 4 ohm or 2 ohm speaker, the power will be automatically limited to 15W. Artificial Material: this New-designed stereo amplifier is made of noble black immersion gold circuit board, PAM8620 chip, imported KEMET speaker capacitor, large-capacity filter capacitor for channels. Besides, 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 is with 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, over heat protection, overcurrent protection, overvoltage protection, undervoltage protection; what's more, EMI is allowed to pass. Additional Function: it is available to connect external mute function (MUTE: High level mute, factory default low level); available to add an external Shutdown (SD: the chip will be Shutdown at low electricity level, factory defaults high electricity level.
