hello everyone,

can any one please tell me where is the input power supply terminal in the circuit diagram (click here).
iam really confused with the term DC 12V AND PA 12V,


IS THESE TWO ARE TWO DIFFERENT POWER SOURCE OR A SINGLE POWER SOURCE ?

PLEASE MAKE ME CLEAR.

GREETINGS

 

 

Without more information I can't tell, but I'm betting they want a high power power supply, and a well regulated power supply. The high power power supply will draw a lot more current, while the regulator power supply must be quiet.
