MB Loudspeakers are designed for audio applications. Full range audio program signal is expected to
be used as input. Although time-shaped limiter systems are implemented, using high energy band-
limited signal, or exteme equalization (boost) on a full range signal may damage this equipment.
Overload and clipping must be avoided inside all of the equipments in the audio signal chain, since
there is no way to prevent distorted sound or possible damage to the loudspeakers when audio signal
at their input is already distorted.
are designed to be used within ambient temperature range 0°C - 45°C. Higher or
lower temperatures could cause the system to shutdown or result in components failure. Take care to
avoid direct intense sunlight on heatsink. This could raise the temperature of heatsink and force the
amplifiers to protection-mode to avoid permanent damage.
If MB Loudspeakers are used in horizontal position, cooling efficiency of the heatsink is reduced. In
this situation take care to evaluate ambient temperature and SPL level you need, to predict if the
margin is still reasonable before thermal
In order to avoid possible dangerous short circuits when touching other equipments or cables, please
consider that connectors panel and heatsink are at Ground level.

Digital converting/processing time inside MB Loudspeakers results in 1,5ms (milliseconds) delay for
all of MB models, referred to input signal. Use of different loudspeaker systems (provided with
analogue, digital, or no processing) in combination with MB Loudspeakers should be carefully
evaluated. Delay difference should be compensated, if needed, to avoid destructive acoustical
interference.
Thermal protection operates when heatsink (internal) temperature reaches 85°C. As a consequence
the amplifiers will shutdown, and automatically restore when the temperature decreases below
mentioned threshold.

protection will shutdown the amplifiers.
In case one of the protection systems is engaged and doesn’t automatically restore when the cause is
removed, you can restore it manually disconnecting mains and reconnecting after 15 seconds.
