DROK 15W+15W 2.0 2pcs 12V Amplifier Board, Dual Channel Audio Amplifier Board PAM8620 DC 8-26V 24V Digital Stereo Amp Module Class D Mini Power DIY Amplify Circuit for Sound System Speaker

DROK DC 12V 24V Audio Amplifier Module Parameters: Working voltage: DC8-26V, can be operated by DC 12V 24V Output power: 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 Input methods: single-ended (default) difference (to choose by the jumper) Efficiency: >90% THD (total harmonic distortion)&noise: <0.2% Low quiescent current Noise suppression Size: 75.69*41.96mm Materials: high-grade pure black immersion gold circuit board, import WIMA red sound capacitor, each channel large capacity filter capacitor. Special customized pure black copper terminals, gold-plated audio input terminals. Protective functions: input reverse protection, short-circuit protection, over-current protection, over-heat protection, over-voltage protection, low-voltage protection, EMI. Other functions: External mute function (MUTE: High level mute, factory default low level) External turn-off function (SD: Low-level chip turn-off, factory default high level) To use the mute/sd function, just remove the resistance next to the MUTE welding spot and add a switch between the welding spot under the resistance and the welding spot next to MUTE/SD. Package including: 2x Audio Amplifier Module

• Parameters: DROK audio amplifier board 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 module 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.
