What to do if my Nagra Amplifier shuts down in Protection Mode?
The Nagra Amplifier might shut down to protect itself due to several reasons: * **Heavy clipping:** Restart the amplifier and reduce the volume. * **Overheating:** The amplifier will automatically restart once the internal temperature drops below 60°C (140°F). * **DC problem:** To prevent speaker damage, the amplifier shuts down. For this issue, contact your Nagra dealer.
