HS2510 OEP8W digital power amplifier board mono module dual section lithium battery 7.2V/8.4V high power 10W
1. Make sure the line is connected and power on again. If the line is not connected properly, during the playback process-poor connection of the speaker wire will cause damage to the power amplifier chip. The self-inductive voltage of poor speaker contact will break down the amplifier chip.
2. The speaker cable should not exceed 60cm as much as possible. Be sure to use a professional audio cable if it exceeds the length.
3. When the board is powered on, the hands cannot touch the circuit of the power amplifier board, and the human body will cause the board to work abnormally and damage the power amplifier chip.
4. The human body should avoid touching the board with static electricity as much as possible. Static electricity will seriously damage the board.
5. The input audio cable must use shielded cable, do not replace it with a long cable. Wires exposed in the space induce space electromagnetic waves, and after amplification by the power amplifier, various interference sounds will appear in the horn.
6. The power cord must use 1.5A thick wire.
7. The input volume must be reasonable. If the input volume is too high, the input of the power amplifier is saturated-the power amplifier is not working properly, and the power amplifier chip will be damaged if it exceeds the amplification capacity of the power amplifier. The input volume is too low, resulting in the amplifier does not reach the output power of the amplifier itself.
8. The input volume is turned on at the maximum, and the speaker is severely broken. Put a 1K resistor in series with the IN+ input pin, and achieve a voltage division in series with the input 1K resistor of the power amplifier board, the volume immediately becomes 50%, half of the volume. Reasonably choose the resistor in series to prevent the speaker from breaking or distorting when the amplifier board is at maximum volume.
