xDR-16 expander
Add up to two xDR expanders to a single MixRack system.
Add one xDR expander to a linked or dual MixRack system.
Note -
The xDR must connect to the MixRack
The MixRack Port B must be fitted with ACE
Check the MASTER Port B Mode setting in the Surface MIXRACK / Mixer Pref / Port A/B Setup screen or Editor Setup / Mixer Preferences menu. Choose 'Redundancy Off: In1-64 from Link1' when connecting one xDR-16. Choose 'Redundancy Off: In1-32 Lnk1, 33-64 Lnk2' when connecting two xDR expanders. See here for more information.
A MixRack NETWORK port must be bridged to the ACE card BRIDGE socket using the short CAT5 cable provided.
Use ACE card Link 1 to connect the first xDR expander. Use Link 2 to connect the second xDR.
The xDR expanders must have compatible but unique IP addresses. They will not connect if addresses are incompatible or identical. The easiest way to work with the xDR is to use the default reset network addresses.
If you are connecting two xDR-16 expanders then change the IP address and Unit Name of one before connecting the second. Each xDR expander must have a unique Unit Name.
The xDR looks for a MixRack with default 192.168.1.1 IP address. It connects automatically if it finds it. If the MixRack has a different IP address you will need to add the xDR expander manually. To do this go to the Surface UTILITY / Network / Expander Setup screen or Editor Setup menu / Expander Setup page.
Patching Inputs
To patch single inputs use the channel PREAMP screen.
To patch a range of inputs use the Surface MIXRACK SETUP / Mixer Pref / Quick Input Source Select screen.
Patching Outputs
Use the OUTPUTS / Port B ACE screen to locate and patch to the xDR XLR and Port B outputs. If you are using the xDR Port B then you can change which block of 8 ACE channels to feed the XLR sockets. Choose this in the MIXER SETUP / Mixer Pref / Expanders screen or Editor Setup Mixer Preferences menu.
