The amplifier board output must only be connected to passive speakers. Do NOT connect it to active speakers or constant-voltage speakers.\u003cbr\u003e2. The amplifier board is powered by DC 24V–48V. Higher voltage yields higher output power, but the input voltage must never exceed 48V. Also, the positive and negative terminals of the power supply must not be reversed, as this will permanently damage the amplifier board.\u003cbr\u003e3. The negative terminals of the left and right channel outputs of the amplifier board must not be connected together, as this will cause the amplifier to burn out.\u003cbr\u003e4.
