Auto-off 

It takes about 20 minutes to enter the standby mode even after the input signal is shut-off.  This is a feature,
not a bug, because it prevents unnecessary on and off switches.

Reset the amp 

After triggering the protection circuitry, one can reset the amp by either 1) turn the power switch on the
plate to off position and then back to on position, or 2) unplug the power core and then plug in again.  The
former is recommended.
