Shared power connection：
Shared power means that the power supply for the power amplifier and the spectrum power supply are the same.
The shared power supply does not need to be connected to the GND line.
When connecting the power supply, make sure that the power supply voltage is within the allowable range of the spectrum.
Independent power connection：
Independent power supply means that the spectrum and the power amplifier use two different power supplies.
The independent power supply needs to be connected to the GND of the output terminal of the power amplifier.
The GND here is the GND of the output terminal of the power amplifier, not the ground terminal of the household AC power.
Type B is with a shell, the shell material is acrylic, the following picture shows the effect of the shell:
