What to do if my Denon PMA-1510AE Amplifier power switches off suddenly and the power indicator flashes red?

This issue can occur if you are using a speaker with impedance not supported by your unit, or if the protection circuit has been activated because the core wires of different speaker cables have touched or a core wire slipped out of the terminal and is touching the unit’s rear panel. Please use speakers with the specified impedance. Unplug the power cord, twist the core wires together tightly, effect termination treatments, and reconnect.
