Hi Welcome to DUC

You can of course connect the Eleven Rack with the Tascam mixer.

The mixer does not have S/PDIF or AES/EBU inputs so you have to connect via analog. You take a line level output from the Eleven Rack and connect it to a line level input on the Tascam mixer. You would normally use the Main Output XLR connector(s) on the rear panel to go into a 1/4" TRS (balanced phono) channel input on the Tascam. So you need a XLR to 1/4" TRS balanced cable to do this. You need to go into the model 12 on TRS not XLR because this is a line level not mic signal. If you want to run stereo out of the Eleven Rack, say if you are using stereo effects in the Eleven Rack then you'll need two cables and use one of the two stereo channels the Model 12 has.

If you are new to all this just get mono running first. Get one thing working at a time. Get the Eleven Rack working to monitors connected to its Main Outputs, then get the Main outputs connected to the Model 12 so you can hear the output in monitors/headphones connected to the Model 12, then get it working as a recorder or interface to a DAW if that's what you want. Do one thing at a time, checking as you go. The output meters in Pro Tools are super handy for seeing signal levels/debugging things, described in the Eleven Rack documentation.

One hassle with this setup is you don't get a dry guitar signal to the Model 12/DAW, so if this was me I'd put a DI box in front of the Eleven Rack to split off a DI signal to a mono Mic input on the Model 12. Then you can use that later on for reamping through the Eleven Rack. And/or if you use Pro Tools you have all those amp sims and effects available in the Avid Complete Plugin bundle and can reamp/tweak through those, but that all starts by also recording the dry guitar DI signal when you also record the Eleven Rack output.

Those Tascam mixers look neat, multi-channel audio interface (with ASIO support), and HUI/MCU control surface support.
