Sub 2 Power ON/OFF issue

Hello Team,


One of my partner have installed Sub2 in a Home theater Setup, when he Turns ON the entire setup by a dedicated Power Switch (dedicated MCB) and if the Subwoofer was turned ON in previous cycle, in this case he have to press the standby button from the back of the Subwoofer to power ON.


Please suggest if there is any solution to the same.


Can you please help me to identify the problem and solutions to resolve the same?
