Why won't my Dynaudio BM9S Subwoofer switch on?
If your Dynaudio Subwoofer isn't turning on, there are a couple of things to check. First, make sure the AC mains cable is securely connected and that the mains switch on the back of the subwoofer is in the ON position. Also, verify that all signal cables are properly connected.
How to fix Dynaudio BM9S Subwoofer that won't switch on automatically?
If your Dynaudio Subwoofer isn't automatically turning on, ensure all signal cables are properly connected and that the subwoofer output on your source device is enabled.
What to do if my Dynaudio BM9S Subwoofer is on but there's no sound?
If your Dynaudio Subwoofer is on but not producing any sound, several factors could be responsible. First, ensure all signal cables are properly connected. Then, check the bass management settings on your source device to confirm the subwoofer hasn't been disabled. Also, verify that the subwoofer volume level isn't muted or set too low on both your source and the subwoofer itself. Gradually increase the volume on both devices to test the audio output.
Why does my Dynaudio BM9S turn off while playing music?
Your Dynaudio Subwoofer might be turning off during music playback because there's not enough low-frequency signal in the audio. This can occur with content that doesn't have many deep bass frequencies, like dialogue-heavy scenes. The subwoofer should automatically turn back on when it detects low-frequency signals. Alternatively, you can manually turn the subwoofer off and on using the main power switch.
