Troubleshooting

  – If the Power LED lights green and there 

is no sound, check your input signal, 
e.g. by switching speakers.

  – If the Power LED does not light at all 

and there is no sound, check the fuse. 
If you have replaced the fuse and there 
still is no sound, contact your Dynaudio 
Professional Dealer.

  – If the protection LED lights red, check 

the temperature of the heat sink. If it 
feels hot, turn off the speaker and wait 
for about ten minutes to allow the am-
plifier to cool off. Turn it on again. If it 
works now, it is OK – but you may need 
more air circulation around your speak-
er to avoid overheating to occur again.

Care

Components of the highest quality are used 
in your BM12 mkIII. This assures years of 
trouble-free operation. Following precau-
tions should still be made though. Avoid 
running the system into severe clipping. 
Although there is an advanced protection 
system, you may be able to destroy your 
speakers by severe overpowering. When 
a noticeable distortion occurs, please turn 
down the level to your speakers.
Avoid hot-plugging the equipment con-
nected to the monitors. Always turn off the 
speaker and other equipment when plug-
ging or unplugging signals, or switching 

equipment on or off. Do not touch the drive 
units by hand. The tweeter especially uses 
a  very  fine  fabric  dome  with  an  ultra-thin 
coating.
