Precautions:
1Recommended power supply voltage DC8~24V,Exceed26VThe chip will be burned.
2,catch4ΩPower supply does not exceed the horn16V,catch8The power supply does not exceed when the Om speakers exceed24VEssence
3Power supply current recommendation2Aabove.
4The positive and negative electrode of the power supply cannot be connected, and the anti -chip is burned; this module only applies to the power supply of the single power supply, and the power supply cannot be connected.
5, Ensure that the input sound source signal is in0.5V~1.5V
6Do not be too long, guarantee1Appropriate within rice
7Pay attention to static electricity protection. Before contacting the contacted panel, you need to release the static electricity on the hand to avoid static electricity to break through the power amplifier chip.
More sensitive.
8It is recommended to use the rated power of the speaker30WAbove, avoid the heating and burning of the horn
Fault investigation
1,After power -up, the speaker“puff”No response after one sound
1)Check whether the horn impedance is too small and the power supply voltage is too high. The instant large current makes the chip enter DC protection; try to reduce the power supply voltage and restart.
2)Check whether the power supply power supply is too small and the horn is too small, try to replace the high -power power supply, generally2AThere is no problem with the power adapter.
2,Play music“Nourishment”Murmical
1)Replace the sound source to see if the sound source itself comes with noise.
2)Whether to connect the amplifier input or not is the problem of the amplifier itself
3)Using a shielded audio cable, whether it is a thread quality problem to introduce noise
4)Whether the speaker is a problem with the speaker itself
5)If the power supply is replaced, is it the noise introduced by the unstable power supply?
3,Heat and smoke during the speaker playback
The power of the speaker is too small, replace the high -power speaker or reduce the signal input
