1. Can I add an XDR-16 to this setup even with a slave?

Yes it is possible to add 1 XDR16 expander to your dual mixrack setup. You will need to make sure redundant link is turned off in the Port B options page of the Master Mixrack. You then need to connect your Slave mixrack to Link 1 of your Master mixrack Port B ACE module and the expander to Link 2.
Remeber all devices on the network must have a unique and compatible IP address.

2. Will the new version of the software allow me to assign the outputs of the IDR-16 to be usable? They are so limited as to be unusable in the existing setup. Is there no way to assign those outputs now?

---

This is possible in the current firmware.
To do this go to the outputs page and select your slave mixrack from the drop down box at the top of the screen. Select an output socketm in the output source select you will have a list of output types listed such as:
Mixrack inputs (slave mixrack inputs)
ACE (any signal you send out of the master mixrack port B slot will be available here)
e.g. To output mono group 1 out of Slave mixrack output socket G1: – go to the outputs page of your master mixrack and select the Port B tab. assign Mono group 1 to port B channel 1 – then select your slave mixrack from the drop down menu at the top of the outputs page – select socket G1 of the slave mixrack and set the output source as ACE channel 1 – you should now have mono group 1 coming out of the first output socket on your slave mixrack.

Also make sure your slave mixrack ACE link is plugged into link 1 on the master mixrack Port B, to avoid any routing problems.

Hope this helps

And to add to the original question, how about this as a possibility? I apologize if this was answered elsewhere.

What if he added another M-ACE card but put in port B of his slave?
Then connect the xDR-16 to Port B of the *slave* mix rack.
I’m still assuming firmware v 1.70, which is now current.

This is for those who already have a slave mix rack, but their slave’s input and output count is too low (i.e. for slaves smaller than the iDR-64). Can they later build the *slave’s* I/O count with the expander so the expander’s I/O appears on channels 65-128?

And assuming this arrangement would even work, how would any given T-Series expansion card in Port B of the xDR-16 behave? Would it behave as expected in the xDR-16 regardless of the upstream mix rack configuration, or would that card not function properly if at all?

Just wondering what’s possible as we use equipment for different applications.
