    Question DC Protection?


    I've got Vitus RI-100 and now when I try to turn it on - it started to initialize as usual, then message "warning dc protection" appears and that's all. Can only be switched off with plug removed from the socket.

    Is there a way to fix this?

    It might be sensing DC leakage coming from the output of your preamp and it’s shutting down the amp to protect it from amplifying the DC and blowing your speakers up.

    Probably detecting a DC offset at the amplifier output which would be extremely dangerous to your speakers. I would definitely disconnect it and have it checked out.
