This amplifier board supports a DC 19-51V input, with a minimum operating voltage of 19V and a maximum operating voltage of 51V. Within this voltage range, higher input voltages increase output power. Three DC power adapters are recommended. 24V\/5A or higher DC power adapter (common power supply, cost-effective, suitable for low-power speakers under 5-6 inches). 36V\/8A or higher DC power adapter (common power supply, slightly more expensive, suitable for low-power speakers under 6-8 inches, recommended). 48V\/10A or higher DC power adapter (relatively more expensive, but provides higher output power). Wide input voltage support: supports DC 19-51V. The higher the voltage, the greater the power.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eS600X Bluetooth Amplifier Board Instructions:\u003c\/p\u003e\u003cp\u003e1.

For example, if you're using AUX mode one time, after a power outage, it will prioritize AUX mode the next time you power it on. If you're using Bluetooth mode one time, after a power outage, it will still prioritize Bluetooth mode the next time you power it on. Simply short-press the multi-function knob four times to switch between input modes, making it very convenient.
