> I've bought an UFX II, and I notice that analog inputs (1 to 8) doesn't have 48v. Is that right?
Yes because these are Line Inputs and not Microphone inputs, see manual.

> I can't plug microfones on that inputs?
Not directly, because these are line inputs and not Microphone inputs, see manual.
Its possible if you have an external Mic preamp with analog outputs.

> The only inputs with 48v are 9 to 12?
Yes but only if you enable 48V in TM FX for these inputs.

Plugged in usually via ADAT.
ADAT has 8 channels à 44.1/48.
With 88.2/96 multiplexing is used and then you have only 4 channels.
192 = only 2 channels.

So if you want to max the number of channels you can connect
2 XTC with in total 16 additional Mics @44.1/96.
Or 1 XTC with 8 Mics @88.2/96 using ADAT1 and ADAT2.

With an UFX+ you could have plugged up to 8 XTC via MADI.
MADI allows for 64 channels via optical fiber which can be up to 2km long.

-yes
-yes the XTC is the only preamp AFAIK which fully integrates into the TM FX instance of your UFX II
so you can control the gain settings and some other stuff and store all this digitally in snapshots
this remote control works via MIDI.
If you would have chosen UFX+ then this all would go straight over one fiber cable which can be 2km long
and MIDI control signals are sent also via MADI by using some unused bits in the protocol.

So if you have the flexibility / budget, I would suggest to upgrade to UFX+ to reduce the amount of cables
and to enable for even more channels in the future.

Otherwise all is fine, keep UFX II, get XTC, get 2 ADAT Cables (can be up to approx 15m), get Midi Cable to get the remote control working, you need to configure the XTC as so called "AUX device" in the TM FX instance of your UFX II.

Oh, ok, sorry. Got it. Just with UFX+ via MADI, we don't need the MIDI cable.

Thanks for all the help. If something else comes by (when I buy XTC), I'll ask for your help again. :-)

Ramses, sorry, one more question:

If I want to use the XTC mic inputs with my UFX II, and remote control it (midi only):
. UFX II MIDI out --> XTC1 MIDI in (connecting XTC1 ADAT out to UFX II ADAT in)
With this setup, I can use and remote control the extra 8 mic input on TM, right?

Now, if I want to remote control two XTC with my UFX II?
. UFX II MIDI out --> XTC1 MIDI in (connecting XTC1 ADAT out to UFX II ADAT in)
. XTC1 ?? --> XTC2 ?? (connecting XTC2 ADAT out to UFX II ADAT out2)

Many thanks.

Thanks.

And if I want one XTC with UFX II @96kHz (8 mic inputs), I'll have to plug ADAT out 1 and ADAT out 2 to UFX II (S/MUX format), right?

Ramses, the more I talk to you, the more I read the manuals, the more I'm confused if I keep the UFX II or switch to UFX+.
Ok, here some questions that will make me decide if I switch the interfaces or not (sorry the boring...):

- Does the UFX+ and UFX II have the same top quality preamp and conversion?

- When using MADI connection, whats the higher sample rate, if ONE or MORE XTC are plugged with an UFX+? All @44.1/48 or 96kHz, no matter the number of XTC connected (with 8 mic inputs) (double and quad speed)?

- ADAT stay at no higher than 44.1/48kHz. To put @96, we have to use ADAT out 1 and 2. Does MADI have this same issue?

- Whats the thing with "sample delay" on MADI connections? If I buy a XTC and use MADI, do I have to do something manual (on XTC or TM)? Does ADAT have the same "delay" thing?

- I have a Mac Pro with USB 2.0. Is the UFX+ 3.0 full compatible with Mac? Can I use the 3.0 cable too?

I'm very sorry with all this questions, but I have to make a quick decision in the next days.
Thanks!

Hmm... I have several friends who tried to put an PCIe USB 3 into a Mac Pro, and the results were not good at all (Apple…). 

Anyway, here’s my last 2 questions (I hope):

1. I can order an UFX+ and use the MIDI, ADAT and USB2, as it were an UFX II (full compatibility)? I expect to buy an new PC (with usb3) in 1 year or so. When that time comes, I switch to MADI with usb3. What do you think? Can I really use UFX+ with USB2 slot and cable on my Mac with any issues?

2. Now, for main question, this is what I REALLY need to my studio:
UFX (II or +) -------- 4 mic inputs @96kHz
XTC -------------------8 mic inputs @96kHz - ADAT out1 (1 to 4), ADAT out2 (5 to 8)
Basically, I need 12 mic inputs @96kHz with UFX and XTC.
Is it possible, right?

Many thanks!

Ramses, many, many thanks for your support!

I think you've convince me to switch to UFX+. And I'm going to try the USB 4x with USB3 controller, as you suggest. :-)
Anyway, if it fails, the UFX+ is a 2.0 compatible and ADAT possibility until I buy my next machine.
And then, of course, the incredible expandability up to 4 XTC @96kHz with MADI...

By the way, just curious, what's the sample rate you're using on your studio?

Thanks!!

I've found myself printing and indexing "how to" comments into a secondary manual.

this exchange of ideas and information has been very enlightening and valuable...thank you to you both.  Of course, most of the forum exchanges prove to be equally valuable.

Thanks, Knuckled47.

Ramses, I've order the UFX+. Is on his way. :-)

This question is off topic (if you want, I can make a new post):
When I'm mastering and mixing, I should not use UFX EQ and Compressor on the MAIN OUT of Total Mix with my DAW Cubase 9, right? With that, I can create an illusion and double the EQ and comp. used on TM + Cubase, and when I export/bounce to WAV, the EQ and comp. of RFX are gone, right?

(I've already send UFX II, so and can't do this kind of tests).

Tks!

Thanks, vinark.
Honestly, I was almost sure about that. I just want to hear from you, guys.

Just to inform, I've suggested RME to two producers with studios, here in Portugal.
Continue the excellent work. ;-)
Thanks for all the support.
