1.There are 2 sorts of audio enter mode, how am i able to select？
This amp board has two enter modes: Bluetooth and AUX.When audio indicators are enter from each modes on the similar time, the amp board will give precedence to the Bluetooth mode; for those who want the AUX mode, make it possible for the Bluetooth connection has been disconnected.
2. How to decide on a speaker?
Generally used audio system are typically 8 ohms, and the constructive and unfavourable polarity should not distinguished, and the impact is similar. 4 ohm audio system can be used. In case your speaker has a low energy, it might be between 10W-30W. The ability provide voltage is smaller to forestall the speaker from burning after the amplified sound. For instance, select an influence provide under 15V. In case you are a 50W-300w speaker, don’t be concerned about the issue of speaker burnout, you’ll be able to select a 12-24V energy provide. The upper the voltage you select, the better the sound or energy that may be output.
The ability 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 facility fully or unplug it for a very long time, you’ll be able to unplug the DC plug on the machine.
