•
With a DAL bus, the cables are run in a star arrangement and with Ethernet in a tree arrangement (from
device to device)
•
Both the maximum cable lengths and the cable specifications must be observed
•
Up to 4 loops per DOM4-8 or DOM4-24
•
Observe the max. number of the Loop Isolator Module (LIM) and the ring loop length depending on the
amplifier used. - See tables in chapters 3.4.2 and 5.1.2.
•
Up to 5 spurs with more than one loudspeaker per ring loop (with EOL)
•
Do not route outbound and inbound rings conductors in the same cable or the same conduit
•
A single loudspeaker output of a DOM may be loaded with the max. channel amplification power of the
connected amplifier. In this case, the other loudspeaker outputs of the same channel may not be used
•
Up to 500 W per loudspeaker output / per ring loop
•
The total power of all loudspeaker outputs that belong to one channel may not exceed the channel power of
the connected amplifier
Observe the max. cable lengths and cable specifications.
The DOM protocol 3.0 cannot be used in systems with system communication unit (SCU). The system
