Expanded multiple iDR system
This diagram
shows an iDR system with two iDR-8 units and both expanders
fitted. A system could also be created with iDR-4 units or a mix
of iDR4 and iDR-8 units. DR-Link is only required to connect to
the expanders, not between the main units. Make sure you
connect DR-Link to the iDR 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.
