In case your speaker has a low energy, it could be between 10W-30W. The facility provide voltage is smaller to forestall the speaker from burning after the amplified sound. For instance, select an influence provide under 15V. If you’re a 50W-300w speaker, don’t be concerned about the issue of speaker burnout, you may select a 12-24V energy provide. The upper the voltage you select, the better the sound or energy that may be output.
The facility change on the board is a standby change. After the change is turned off, the machine is in a low-power standby state. To show off the ability fully or unplug it for a very long time, you may unplug the DC plug on the machine.
