The ADN D1 and ADN C1 conference units  
The ADN D1 delegate unit and the ADN C1 chairperson unit are part of  
the Sennheiser ADN conference system.  
To ensure full operational reliability in a redundant ring topol-  
ogy, the hardware of the ADN C1 and ADN D1 has been revised.  
If you combine conference units with hardware revision 1 (no  
marking on the type plate) and conference units with hardware  
revision 2 (“HW: v2” is printed on the type plate), fail-safe  
operation is only possible to a limited extent.  
̈ In a redundant ring topology, only use conference units  
with hardware revision 2.
