5.5.2 Alternative Setup
Without LS 5900 F Loudspeaker
The CU 5905 supports additional discussion units when the loudspeaker is not used with the DC 5900 F Flushmount
discussion unit. The numbers listed below are calculated with a DIS GM gooseneck microphone.
The flushmount units also operate with the Shure MX4xx series gooseneck microphones, though the power
consumption is slightly higher. Subtract six units from numbers below to determine the maximum number supported
by the CU 5905.

5.5.3 Using Junction Boxes
The JB 604 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.
