Adding 2 expanders to a single rack system
This example shows two xDR-16 expanders connected to an iDR-16 MixRack to increase the number of
physical mic/line inputs to 48 and XLR outputs to 24.
ACE Link 1
Step 1 Install the ACE option card into the MixRack
Port B slot following the instructions provided.
Step 2 (Optional) Install any option cards you require
into the xDR-16 Port B slots.
Step 3 Bridge the MixRack network over ACE by
connecting one of its NETWORK ports to the ACE card
BRIDGE socket using the CAT5 jumper cable provided
with the card.
Step 4 Connect the first xDR to the MixRack by
plugging a suitable CAT5 cable between the xDR ACE
port and MixRack Port B ACE Link 1 socket.
Step 5 Power up the system with the one xDR. The
xDR will connect automatically if the MixRack IP address
is set to its default 192.168.1.1. If not, add the xDR
manually using the UTILITY / Network / Expander
Setup screen.
Step 6 Change the IP address of this xDR from
192.168.1.20 to 192.168.1.21 (and also change the Unit
name if you add the xDR manually) using the
UTILITY /
Network / Network Settings screen so that it does not
conflict with the address of the second xDR. Touch
Apply to reboot the system.
Step 7 Add the second xDR by plugging a CAT5 cable
from its ACE port to the MixRack Port B ACE Link 2
socket. The xDR will connect automatically or need to be
added manually as described in Step 5 above.
Step 7 Check expander status using the UTILITY /
Network / Expander Setup screen. Also check that the
firmware versions are the same.
Step 8 Patch the xDR inputs and outputs. This is
described elsewhere in this guide.
Note 1 - MixRack Port B ACE Mode
Choose the third Mode (Redundancy Off – 1-32
Lnk1, 33-64 Lnk2) . This is set in the
MIXRACK
SETUP / Mixer Pref screen.
Note 2 - Compatible IP addresses
The xDR expanders and iLive system must have
compatible IP addresses.
The xDR looks for a MixRack with default address
192.168.1.1 and connects automatically when it
finds it. If the MixRack has a different address you
will need to add the xDR manually.
If the IP addresses have been changed or your
system fails to connect you may need to reset the
network settings. More information on network
settings is described elsewhere in this guide.
Note 3 - Different address for each xDR
Unless the IP address of one has already been
changed, both xDR expanders will have the same
default address of 192.168.1.20. For this reason
the address of one must be changed before the
second is added to the system.
Note 4 - Firmware versions
Must be the same for the xDR and the MixRack.
Check the Allen & Heath web site for the latest
version. The xDR firmware can be updated using
the iLive system or a laptop running Editor.
