  If your Dynaudio Subwoofer is on but producing no sound, there could be several reasons: * There might be no signal reaching the subwoofer inputs. * The subwoofer could be disabled in your processor or receiver's bass-management settings. * The subwoofer volume might be muted on your processor/receiver or on the subwoofer itself. To resolve this: 1. Ensure the system is off before making changes. 2. Verify all signal cables are securely connected. 3. Check the Bass Management settings on your amplifier or receiver. 4. Carefully increase the subwoofer volume on both the amplifier/receiver and the subwoofer GAIN control.

  If your Dynaudio Subwoofer isn't automatically switching on, the issue is likely that no signal is reaching either of the subwoofer's inputs (the LED light will be red). To resolve this: 1. Make sure to switch the system off first before making any changes! 2. Check if all signal cables are connected properly. 3. Check if the subwoofer output on the source is engaged.

Why does my Dynaudio Sub 3 Subwoofer switch off when music is playing?
- L
  lopezedwinAug 19, 2025
  Your Dynaudio Subwoofer might be turning off during playback because it's not receiving enough low-frequency signals. This often happens when the content you're playing (music or movies) doesn't contain very deep bass frequencies, such as during extended dialogue scenes. The subwoofer will automatically turn back on when it detects low-frequency signals.
