Q: The fan in the Power Stand comes on when I strike a chord on my Guitar. Is this normal? A: Your unit is functioning properly - no problem.


The fan in the Model II Power Stand comes on when the input signal level goes over a certain limit, regardless of what the internal temperature of the unit is. That way, the unit never gets too hot to where a fan needs to be on constantly.

There is a Firmware Update that addresses the fan behaviour. See: [[L1® Model II Power Stand Firmware Updates#Fan_Behavior]]

Starting in units manufactured in late 2014 and later,  the fan now runs quietly, constantly, while the Power Stand is powered on. This too is completely normal.
