Comparison Table of Input Voltage and Output Power
The above output power is peak power, not rated power. The peak output power data comes from new product data provided by Texas Instruments in the United States. This data is obtained in a specific, ideal state with TDH=10% 1kHz.
According to the above table, the higher the input voltage, the higher the output power; The lower the speaker impedance, the higher the output power.
If you want to achieve good power output, a power adapter of 24V 36V/5-10A or above is a recommended choice.
