Physical display

NOTE:

1. Keep 2 meters away from router to avoid WIFI interference

2. 8~24VDC is recommended; upper than 26V, it wi" damaged.

3. Driving 4 load, power supply must be under 12V; and driving 8 load, supply must be under 24V.

4. The supply current must be 2A at least.

5. If the module works upper 20W x 2, a cooling fin will be needed.

6. The line connecting speaker with module should be within one meter.

7. ESD protection, please release ESD on your hands before you contact the module.

3. The speaker tapped when power on.

1) Check that the speaker load is so small that the current through the speaker is enough for chip goes into DC protection. Try to lower the supply and restart.

2) Check that if the power supply is low that cannot drive the speaker. 2A power supply current is ok.

4. Floor noise in speaker when playing
