Features:
- This is the actual test data on the instrument.
- The output power is related to the supply voltage current, the speaker impedance, and the input of the audio source.
- When the power supply voltage/current is sufficient, the power supply voltage is usually higher and the relative output power can be made larger.
- Speakers with different impedances also have different output powers. Generally, the speakers have smaller impedance and more power.
