Interesting would also the channel cross talk (1kHz / 20 kHz) if one input is opened or shorted While using only ONE DAC

Many Window's programs, as e.g. Arta and Audiotester, run on Mac using wine. Only changing the sampling rates in the programs does not work properly. You have to do that (additionally) manually using Audio-Midi-Setup (in my older OS X this is in the utilities folder).

MATAA. It has level calibration with automagic reading of the RTX level controls implemented.

Apologies if this has been covered already, but I'm pressed for time and not in a position to read all +200 pages of this topic.

I have two quick questions for the experienced RTX6001 users. Mine was one from the 1st batch, and came with parts I need to install, but I can't find instructions on the RTX website?

Also, I tried updating the firmware after having installed the latest and greatest drivers/software from the RTX website, but it won't let me perform the update as the application comes back with an error message because it can't find TUSBAudioDfu.exe?

Any suggestions you fine gentlemen can provide for the above would be appreciated! Thanks!

Please read the "Hardware modifications" section at the bottom of the first post.

Unpack the files from the downloaded zip file.
The TUSBAudioDfu.exe and the TUSBAudioDfu.xml files should be placed together in a folder. Run the TUSBAudioDfu.exe application from that folder. Once the application has started, locate the RTX6001_i2o2_V0119.bin file where you placed it after download, press Open and Start. That should work.

All set! Thanks Jens, much appreciated! Now where did I put my 8R dummyload?

I can’t seem to grow accustomed to using the RTX6001 for the simple reason of not being able to find software that’s not cumbersome to set up and use. I am a long time Analog Discovery with Audio Analyzer suite package user and I absolutely love it for its ease of use and simplicity, it is what I use on a day to day basis for quick analysis and measurements.

Is a similar software suite available for the RTX6001? I don’t mind spending a bit of money on software that allows me to operate my RTX6001 in similar fashion as I’m familiar with with the Analog Discovery.

Any suggestions would be appreciated, thanks!

I have not heard of the Analog software, so it's difficult to tell what you're after. What kind of measurements are you looking for ("oscilloscope", electronic, acoustic, etc.)? What functionality and features do you need? What computer operating system do you use?

That said I don't think this thread is the right place to ask this question because most audio analysis software tools are designed to work with just about any USB audio interface. Since the RTX 6001 is just yet another USB audio interface from the software perspective, your question is not specific to the RTX 6001.

Ah I'm just now getting caught up on the thread and this issue! So true, distance solves a great many things.

An external transformer really would be the ultimate solution. I would also be quite interested in buying any shielded transformer Jens finds that would help.

I want to be able to simply generate graphs as per the attached image, without having to spend an hour clicking in different menus to set this up. In that regard the Audio Analyzer suite for the Analog Discovery 2 is a godsend!
