Instructions for use:
The volume adjustment knob has its own switch. It rotates clockwise to hear the click sound. Turn on and continue to rotate the volume to increase the volume. The counterclockwise volume becomes smaller. Continue to rotate. After the card is clicked, the amplifier is turned off. The default is turned on after the factory test. Ensure that the input source signal is between 0.5V and 1.5V. It is recommended that the power supply voltage be DC 8~24V, 2A or more, more than 26V, the chip will burn out, and there will be noise below 8V. The power supply does not exceed 12V when connected to a 4Ω speaker, and the power supply does not exceed 24V when connected to an 8 ohm speaker. The working power of the module exceeds 20W*2, and it is necessary to add a heat sink. It is recommended to use the rated power of the speaker at 30W or above to avoid the burning of the speaker. The speaker cable should not be too long, and it should be suitable within 1 meter.
Precautions:
Pay attention to static electricity protection. Before touching the power amplifier board, you need to release the static electricity on your hand to prevent static electricity from penetrating the power amplifier chip. The digital power amplifier is sensitive to static electricity.
