INDICATORS & POSITIONING
Indicators
On the front you will find 2 diodes. These are
positioned just above the Dynaudio Logo.
The green power diode indicates speaker
on/off status. Green indicates; “power on”.
The second diode has two functions. This
will light up orange when the input signal
reaches a level where the limiter is activated to
prevent the internal bass amplifier from
clipping. 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 BM 5A monitor has several built in
protection systems to reduce the risk of hazard
or damage due to overloading.
Both power amplifiers have thermal protection.
This activates if a problem should occur, and
helps protect both the electronics and the
loudspeaker drivers.
There is also a thermal sensor measuring the
temperature on the heat sink. An electronic
circuit will mute the signal when too high
temperature is reached. The protection 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 current is fed to the
tweeter.
The woofer channel has a built in limiter that
protects the woofer unit from too much
excursion. It works by reducing the gain of the
circuit when a certain threshold level is
reached.
Positioning
The BM 5A is designed as a near to mid-field
monitor and can be equally well used in both
stereo and surround setups. Optimal
performance is achieved when positioned 1-3
meters from the listener.
It can be placed on stands or on the meter
bridge of a console provided that the meter
bridge is sufficiently sturdy. For best results the
speakers may be aimed towards the listener in
both vertical and horizontal planes.
Note:
Be aware that proper air circulation around the
monitor for sufficient cooling is necessary. Also
notice that the heat sink is designed to provide
maximum cooling when the monitor is
positioned vertically.
