Shure DDS 5900 User Manual page 26

Higher Unit Count with DC 5900 F Variations
The power requirements for the DC 5900 F discussion unit vary depending on the configuration of the unit. Additional
discussion unit are supported when the loudspeaker is removed and when GM gooseneck microphones are used instead
of the MX4xx series microphones.
The numbers listed below are calculated with DIS GM microphones without a loudspeaker connected. Power consumption
is slightly higher with Shure MX4xx series microphones, so subtract about five units from the tables to determine the
maximum number supported by the CU 5905.

Using Junction Boxes
The JB 6104 junction box adds four additional outputs to a point on the DCS-LAN chain. These four outputs are available
for short-run connections to DUs, protecting the DCS-LAN chain from technical failures or hot-plugging damage. A single
DU can connect to each JB output, with a maximum cable length of 10 m.
