iDR-8 User Guide 31
Fully expanded iDR-8 This diagram shows the iDR-8
with both the input and output expander fitted. Note the
connection of DR-Link which is daisy chained from one unit to
the next. If an iDR-switch unit is also fitted then daisy chain
DR-Link from the last expander to the switch box. Make sure
you plug into the correct DR-Link socket.
Use CAT5 STP cable. A pair of standard 2 metre cables is
provided with each expander. Maximum cable length is 250
metres. This means that the expander units can be used for
remote audio over CAT5 cable.
Expanded multiple iDR-8 system This diagram
shows an iDR system with two iDR-8 units and both expanders
fitted. DR-Link is only required to connect to the expanders,
not between the main units. Make sure you connect DR-Link to
the iDR-8 associated with each expander. Make sure you plug
into the correct DR-Link socket. In this case do not daisy chain
DR-Link from one expander to the other.
Use CAT5 STP cable. Maximum cable length is 250 metres.
Maximum audio matrix is 16x16. The audio link cable carries 8
channels. This can provide a distributed system with 8
common channels and 8 local channels at each unit.
