Great Product, compatible with Presonus
It has the TI chipset approved by most manufacturers including Presonus and works as prescribed. I also wasn't expecting the unit to power my Firestudio Mobile without the wall wart attached but it does. No clicking popping or weird artifacts just a great reliable connection for my DAW. Also Karl my Sweetwater Sales Engineer was extremely helpful and even called me on my order beforehand to confirm I was getting the correct product. As always a great Sweetwater experience!
