915 Generation DY-AP3015 30W X2 Dual Channel Class D DIY Power Amplifier Mo

Precautions for use:
The recommended power supply voltage is DC 8~24V. If it exceeds 26V, the chip will be burned. If it is lower than 8V, there will be noise. When connected to a 4 ohm speaker, the power supply should not 12V, and when connected to an 8 ohm speaker, the power supply should not 24V.
The power supply current is recommended to be more than 2A. The working power of the module exceeds 20W*2, and a heat sink needs to be added. that the input audio signal is 0.5V~1.5V. The speaker cable should not be too long, and that it is suitable within 1 meter.
Pay attention to electrostatic protection. touching the power amplifier board, you need to release the static electricity on your hands to avoid the breakdown of the power amplifier chip by static electricity. The digital power amplifier is more sensitive to static electricity. It is recommended to use a speaker with a rated power of 30W and above to avoid the speaker from being overheated and burned.
Adapter speaker (30W~150W): 4 ohm (8-12V power supply); 8 ohm (8-24V power supply)
Module protection mechanism: power reverse connection protection; short circuit protection; - overheating protection
