Important safety instructions
The lightning flash with an arrowhead symbol within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is

way, such as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
15.WARNING: To reduce the risk of fire or electric shock, this

Troubleshooting
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
Cause
Solution
The subwoofer switches itself off
while music is being played.
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).
– 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.
The subwoofer will not switch on
at all.
– AC mains cable has become disconnected (LED does
not lit)
– Mains switch on the back is switched to OFF (LED does
not lit)
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.
The subwoofer will not switch on
automatically.
– No signal is present on either of the subwoofer’s inputs
(LED lights red).
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.
Subwoofer is switched on but no
sound from the subwoofer.
– 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.

Troubleshooting
Maintenance
Cleaning the subwoofer
Dynaudio loudspeakers require no special treatment apart
from the kind of careful handling you would normally apply to
any high tech product in your home.
DANGER
Dangerous voltage inside!
Cleaning the BM14S II or other system components when
switched on can lead to damages or electric shock.
–Switch off the subwoofer and all other components of your
system when cleaning any of these components.

Note:
Because many different materials like wood veneer, aluminum

materials should not be used. Please avoid any aggressive
cleaning fluids or special furniture polishes as well.
To clean the subwoofer:
–The cabinet and other plain parts should be cleaned with a
soft dry or slightly damp cloth.
–Dust on the woofer diaphragms may be removed with a
fine furniture brush.
Note:
Avoid touching the tweeter domes as any change of their
shape may have an impact on sound quality.
