About power selection:
Board is the use of DC power supply, there are positive and negative reverse protection, positive and negative reverse power off.
The power supply does not allow incorrect connection to the speaker output connector, which can cause the amplifier chip to be damaged.
The maximum operating voltage of 25V (Note: Do not use more than 25V).
If you use a common AC adapter power supply, you must add rectifier filter before you can connect to use. (Note: no-load voltage after rectification is not greater than 25V).
Power supply with 12V / 3A or more, left and right speakers with 4 ohms / 15-30W;
Power supply with 19V / 3-4A above, left and right speakers with 4 ohms / 30-50W [These are just a basic parameter, for reference only].
Such as the power requirements are particularly high, the proposed power supply with 20-24V / 4-5A or more, speakers with 4 / 40-80W.
Speaker output wiring:
Speaker output "+" or "-" are independent, not a total of output, can not be connected to each other. And can not be connected with the power "+" or "-", the error will not sound or cause the amplifier chip is damaged.
Speaker output wiring:
The speaker outputs "+" or "-" are independent and can not be connected to each other.
And can not be connected with the power "+" or "-", the wrong connection will sound is not normal or cause the amplifier chip is damaged.
