Troubleshooting

There may be various reasons why the subwoofer doesn’t function properly in a system without it being faulty. The checklist below will help solve problems you may encounter. Before consulting your Dynaudio Professional dealer, check this list first.

Check this first:

  • Check if all signal cables are connected properly.
  • Check settings in bass management menu of the connected source.
  • Carefully and gradually increase the subwoofer volume level on the source.
  • Carefully and gradually increase the subwoofer volume level on the subwoofer Gain control.

Problem

The subwoofer switches itself off while music is being played.

Cause

There is hardly any low-frequency signal available in the signal. This can happen if the music or movie itself does not contain very low frequencies (e.g. long dialogues).

Solution

The subwoofer will switch on automatically as soon as low frequent music signals are detected. Switch subwoofer off and on again by means of the main POWER switch.

Problem

The subwoofer will not switch on at all.

Cause

  • AC mains cable has become disconnected (LED does not lit)
  • Mains switch on the back is switched to OFF (LED does not lit)

Solution

Make sure to switch the system off first before making any changes!

  • Reconnect mains cable.
  • Switch mains back on.
  • Check if all signal cables are connected properly.

Problem

The subwoofer will not switch on automatically.

Cause

No signal is present on either of the subwoofer’s inputs (LED lights red).

Solution

Make sure to switch the system off first before making any changes!

  • Check if all signal cables are connected properly.
  • Check if the subwoofer output on the source is engaged.

Problem

Subwoofer is switched on but no sound from the subwoofer.

Cause

  • No signal is present on either of the subwoofer’s inputs.
  • In the source’s bass-management set-up, subwoofer has been disabled.
  • Subwoofer volume level has been turned down all the way on the source.
  • Subwoofer volume level has been turned down all the way with the subwoofer’s control.

Solution

Make sure to switch the system off first before making any changes!

  • Check if all signal cables are connected properly.
  • Check settings in bass management menu of the source.
  • Carefully and gradually increase the subwoofer volume level on the source.
