Instructions for use:

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.

It is recommended to use the rated power of the speaker at 30W or above to avoid the burning of the speaker, and the speaker cable should not be too long to ensure that it is suitable within 1 meter.

Precautions:

Pay attention to static electricity protection.

Before touching the power amplifier board, discharge the static electricity on your hand to avoid static electricity from penetrating the power amplifier chip.

The digital power amplifier is sensitive to static electricity.

The positive and negative poles of the power supply cannot be reversed, and the reverse chip is burned.

This module is only suitable for single-supply operation and cannot be connected to a negative power supply.
