sound is too bright; try to set to -1 dB to
reduce treble by 1 dB. If the sound is too
dull, use +1 dB setting to raise the treble
by 1 dB.
Indicators
On the front you will find two diodes. These
are positioned just above the Dynaudio Lo-
go.
1. The green power diode indicates
speaker on/off status. Green indicates
"power on".
2. The second diode has two functions.
When the output stage is close to clip-
ping the LED will light up orange. And it
will light up red when the amplifier gets
too hot. At the same time the monitor
will be muted, in order to reduce the
temperature.

Protection
The BM12 mkIII monitor has several built
in protection systems to reduce the risk of
hazard or damage due to overloading.
Both power amplifiers have thermal protec-
tion. This activates if a problem should oc-
cur, and helps protect both the electronics
and the loudspeaker drivers.
There is also a thermal sensor measuring
the temperature on the heat sink. An elec-
tronic circuit will mute the signal when too
high temperature is reached. The protec-
tion diode on the front will light up when this
happens.
On the tweeter output there is an overload
protection to prevent burning the tweeter
driver in case of overloading. This circuit
will mute the tweeter signal if too much cur-
rent is fed to the tweeter.
Positioning
The BM12 mkIII is designed as a near to
midfield monitor and can be equally well
used in both stereo and surround setups.
Optimal performance is achieved when po-
sitioned 1 to 3 meters from the listener.
It can be placed on stands or on the me-
ter bridge of a console provided that the
meter bridge is sufficiently sturdy. For best
results, the speakers should be aimed to-
wards the listener in both vertical and hori-
zontal planes.
Note:
Be aware that proper air circulation around
the monitor for sufficient cooling is neces-
sary. Also notice that the heat sink is de-
