Step 1: Network settings
Note: Master and Slave MixRacks must have unique IP
addresses and Unit Names.
Make sure both addresses and names have been set
before the two MixRacks are connected together.
Set these in Network Settings
For example: 192.168.1.1 “Master 1-64”
192.168.1.4 “Slave 65-128”
Step 2: Connect Dual-Rack system
Connect the Surface to the Master MixRack using 1x
CAT5 cable in ACE Port A.
Link the Master and Slave MixRacks using 2x CAT5
cables. According to your preference, choose:
Method 1 – Connect a Master Network port to a Slave
Network port. Connect Master Port B ACE 1 to Slave
Port A ACE, or
Method 2 – Link a Master Network socket to its Port B
Bridge socket. Then use one cable to connect Master
Port B ACE 1 to Slave port A ACE.
Refer to Allen & Heath web site for recommended cable
type and maximum length.
Step 3: Set up Dual-Rack system
Using the Surface TouchScreen go to Utility / Network /
Dual MixRack Setup .
Touch Add Slave . Highlight a MixRack in the list to add
as Slave.
Touch Inspect . Details of the MixRack are displayed.
Check that the firmware is compatible.
Touch Apply to add the MixRack as a Slave. The
MixRack reboots and resets its parameters.
Note:
 Channels 1-64 are sourced from the Master MixRack
(Preamps cannot be mapped across MixRacks).
 Channels 65-128 are sourced from the Slave
MixRack.
 Surface audio can only be assigned between
channels 1- 64 (connects to Master MixRack).
 Each MixRack processes its own channels 1-64 or
65-128.
 The Master MixRack processes the 32 buses.
 FX may be inserted on Master channels 1-64 only.
 Channels cannot be ganged across MixRacks.
 The Reset Network Settings recessed switch
restores default single MixRack operation.
