Why does my Denon Stereo Receiver AVR-1909 power off suddenly and the power indicator flashes red quickly?
- R
  Rebecca SmithAug 30, 2025
  If the power switches off suddenly and the power indicator flashes red at intervals of approximately 0.5 seconds, it could be due to: * Using speakers with impedance lower than specified. * Speaker cable core wires touching each other or disconnecting from their terminals, or coming into contact with the AVR-1909 rear panel. To resolve this: * Use speakers with the specified impedance. * Unplug the power cord, twist the core wires together tightly, or redo termination treatments, and then reconnect.

Why does my Denon Stereo Receiver AVR-1909 power off suddenly and the power indicator flashes red?
- A
  Angel GonzalezAug 27, 2025
  The protection circuit in your Denon Stereo Receiver AVR-1909 may be activated because the internal temperature is too high or the speaker impedance is too low or speaker cables are faulty. Here's what to do: * Switch off the power immediately and allow the unit to cool down before turning it back on. * Ensure the AVR-1909 is installed in a well-ventilated area. * Use speakers with the specified impedance. * Unplug the power cord, twist the speaker cable core wires together tightly or redo the termination treatments, and then reconnect.

Why is there no sound from the center speaker on my Denon AVR-1909?
- C
  Christina FrederickAug 23, 2025
  If no sound is produced from the center speaker, it may be because you are playing a monaural source (TV, AM radio broadcast, etc.) in the “STANDARD” (Dolby/ DTS Surround) mode. Try setting the mode to something other than “STANDARD” (Dolby/ DTS Surround).
