    Of course. The ARTA manuals are a good place to start. Have a look at page 9 of the LIMP manual:
    https://artalabs.hr/download/LIMP-user-manual.pdf

    Figure 3.1 is the jig shown in this thread, figure 3.2 is what I recommend so you can include an amplified output. The jig in figure 3.2 will be required if/when you want to connect a mic and take full advantage of ARTA. Check the ARTA manual for more:

    If you want to design with full "spinorama" of data with VituixCAD, 2 channel acoustic measurements are a must. The measurement guide for VituixCAD has more details:

    Thanks for the schematic.

    I'm not sure I understand the added abilities of your unit but I am not questioning the benefit.

    I feel like if I had one in my hand I'd be like one of those guys picking antiques on TV... "Clearly it's a tool or device of some kind, probably used by somebody...". Maybe I should read through this thread again. If I'm still stumped, I may PM you if ok.

    You'll be fine. Nothing wrong with Behringer UMC line of products either TBH, but avoid the UCA products at all costs. I use a Steinberg UR22mkii and couldn't be happier, Steinberg/Yamaha has real solid drivers so their products are always a good choice.

    If you have plans to use a mic with ARTA as well down the road you may want to build a slightly more elaborate jig than what is described in this thread. Only a few more resistors are needed and a switch. In fact, I recommend a few more resistors regardless, it's my preference to always have a power amp in the chain even with basic T/S, gives you added flexibility down the road.

    I've attached a schematic of my jig for you. Enjoy. ARTA jig.pdf

    I am about to pull the trigger on building this box, but am curious if the Steinberg CI2 audio interface I own, as well as the PC will allow me the necessary connections to run the Limp module. Should I be expecting any comparability issues? I noticed a few comments about the Behringer above and got me worried.

    Post a WTB in the classified and keep your fingers crossed.

    Sounds like it's what I am after. I just wanted to make sure my plan to forego the DATS was with merit. I realize there is lots the DATS offers, but in the end I just wanted to be able to deduce T/S at the very least. I will research ARTA suite and what it all offers.
    Cross Spectrum has no stock for the time being and am not sure when they'll get more. Hopefully soon. Sadly the shipping to Canada is quite high. It's always kept me from jumping on one. Ends up costing almost $200CAD to get here.

    ARTA is actually a suite of softwares. It CAN be purchased, but even using the (slightly more limited) FREE versions, if you build that jig, you can use the "LIMP" module to (basically duplicate DATS funtions to) generate T/S parms as well as .zma files - for XO simming (no need for a mic for just that).
    You can create .frd (FR) files (for simming) using ARTA w/a mic. Most here (for BEST results) use a mic calibrated by Cross Spectrum Labs. I've got a CSL'd Dayton EMM-6 mic that I use w/a Blue Icicle.

    Sorry to drag this up... I am planning to buy a Sonarworks XREF20 mic and have a Steinberg CI2 interface.

    Is it correct in assuming I can build this jig and get most of the results I want from a DATS (t/s parameters and impedance curves etc) for the cost of the jig and learning some free software?

    Man, I forget what I did yesterday ... this is from 17'! :o Anyhow, IIRC, it is due to the uca222 being too noisy. Instead of spending more $ on a better soundcard, I just bought a dats.

    Hi Kornbread,

    Did you ever get an answer to this question? I have the same soundcard and see the same problem.

    I ordered a few of .1% resistors suggested earlier in the thread. Made a post in the classifieds if someone wants one without spending $8 on shipping.

    thanks Hong . it just got me wondering . there is not much cost difference a 10w is only $ .98 .

    I use a 2 watt 1% tolerance resistor in mine without issues. I don't know if higher wattage matters.

    does the resistors wattage matter ?
