Is the Isolator compatible to RME devices?

We have serveral RME units in our lab and prove full compatibility. In some cases, bus-powered products need an external power supply.

Please note following appreciation from Matthias Carstens, head of RME:

Hello Daniel,

the isolator arrived this morning. I tested it right away:

- It’s fully compatible with all RME USB interfaces, regardless of whether they’re working in interrupt or isochronous modes. The test was carried out with the maximum channel count. Also, I've flashed the device with a new firmware via USB. No problem at all.

- The power supplied to the device end is surprisingly high. Our bus-powered interfaces Babyface and Babyface Pro overload the isolator anyway, so you’ll have to work with it there on an external power supply. This was to be expected, because at 550 and 800 mA we’re drawing considerably more power than originally planned of course.

- The isolator does exactly what I had hoped it would: it eliminates all problems arising via USB during unbalanced test setup.

I’ve attached two screenshots for you. Two USB audio interfaces were connected to a notebook here (one wasn’t from RME). On one device the analysis software emitted a test signal (1 kHz sine wave), on the other device it was analyzed at the input. The analog connection Out to In is unbalanced. Once with the isolator, once without.

I’ll share this information and the images with you. So if you want to show somewhere that RME has found the isolator to be fully compatible, or want to use the measurements on the website or as visual aids in your presentations, then you’re welcome to do so free of charge.

Best regards,

Matthias Carstens
