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 BM5A MKll. 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. The limiter works over a
certain range, but exceeding this level may
send a severely clipped signal to your drivers.
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 BM5A MKll may be combined with a
Dynaudio Acoustics subwoofer for extended
bass performance, and higher spl if highpass
filter is used. See Setting Up.
