Troubleshooting
If Power LED lights green and no sound, check
your input signal f.ex. by switching speakers.
If power LED does not light at all and no sound,
check the fuse. If replaced and still no sound
contact your Dynaudio Acoustics Dealer.
If protection LED lights red check the
temperature of the heat sink. If it feels hot turn
off the speaker and wait for some 10 minutes to
allow the amplifier to cool off. Turn it on again.
If it works now it is ok, but you may need more
air circulation around your speaker to avoid
overheating to take place again.
Care
Components of the highest quality is used in
your BM12A. This assures years of trouble free
operation. Following precautions should still be
made though.
Avoid running the system into severe clipping.
Even 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 connected to
the monitors. Always turn off the speaker and
other equipment when plugging 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 a ultra thin coating.
Options
The BM12A may be combined with a Dynaudio
Acoustics subwoofer for extended bass
performance, and higher spl if highpass filter is
used. See Setting Up.
