It may be desk or rack mounted but comes standard as self standing with rubber feet. [. . . ] This switching on and switching offis quite normal. The "Protect" function is there to protect the amplifier from a high temperature problems which would only occur if the fan stopped working or became clogged up. In this very rare occurance, the amplifier will shut down and the protect LED will illuminate. The amplifier will automatically restart once it's internal temperature has fallen within "safe" limits. If the protect LED illuminates, it is best to switch the amplifier off, let it cool down and then try it again. If the protect LED illuminates again, please contact either Audio Telex or the company who supplied or installed the equipment.
