4 IDR D-in/out User Guide AP6636
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. Note that the digital or analogue
expanders may be used, but only one input and one output
expander may be added per system. 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.
Working with iDR System Manager The online
Editor recognises any expanders connected. If you are
working offline then a simulation of the expanders is provided.
This is the same for either the analogue or digital output
expander. If you want to simulate a digital input expander then
select this from the File / Preferences / Expander Options
menu. When choosing a digital input as a channel Source you
can select either the AES3 or the SPDIF connection. The
digital input selection is also available as a parameter which
can be stored and recalled in the presets.
For further information refer to the Allen & Heath web site or
contact Technical Support in your area.
