TPA3221 2.1 channel Bluetooth power amplifier board 100W+100W+200W super TPA3116 chip
The power amplifier board is not equipped with a power supply and audio cable, so you need to purchase it yourself.
The power amplifier board supports DC12-30V, with a minimum operating voltage of 12V and a maximum operating voltage of 30V.The higher the input voltage in this voltage range, the greater the output power.
Three specifications of DC power adapters are recommended.
12V/5A DC power adapter (common power supply, cost-effective, suitable for low-power speakers below 4 inches.The output power is not large)
24V/6A DC power adapter (common power supply, cost-effective, suitable for low-power speakers below 5 inches, recommended!!)
DC power adapter of 30V/8A or above (the price of the power supply is relatively high, and large output power can be obtained. It is recommended!!!, Suitable for high-power speakers above 5 inches.)
Support wide voltage input: support DC12-30V/5A or more, the higher the voltage, the greater the power.
