Protection
Within the amplifier, there are DC output protection and overheat protection.
When there is a certain amount of DC in the output, the DC output protection
will be triggered and the front LED will illuminate as red. This may be caused
by a high DC amount in the input, unplugging input cable during operation,
or failure of the amplifier. When the DC amount drops to safety level for a
period of time, the protection will turn off by itself and the front LED will turn
to white.
When the amplifier is overheated, the overheat protection will be triggered
and the front LED will illuminate as red. This may be caused by too low loading
impedance, high environment temperature, overloading the amplifier (close
to or exceed the rated output), or failure of the amplifier. When the temper-
ature drops to safety level, the protection will turn off by itself and the front
LED will turn back to white.
With safety in mind, the Rei has a built-in overload protection. Therefore,
please be careful not to short the speaker cables or the binding posts or input
wrong AC mains voltage. The mentioned operation will permanently damage
the amplifier which is not covered by warranty.
