d&b audiotechnik 30D - Max. Number of Cabinets Operated in Parallel

17.1.2. Max. number of cabinets operated in parallel
The following table indicates the maximum number of cabinets
which can be operated in parallel by one amplifier channel in
order to be able to detect a failure of a loudspeaker component.
Note: The thresholds of the System check function are also
used by Load monitoring to evaluate the system status.
Therefore the values in the table also apply to Load
monitoring. If more cabinets are operated in parallel, a correct
supervision for single component faults is not possible. This is
of particular importance for voice alarm and evacuation
systems.
