Your general opinion of this product.
I was experiencing some hum and buzz in my 1/4" patchbay that I finally traced to my MPC 2000XL. I was under the previous assumption that the MPC had balanced TRS out but I was wrong. After adding the JDI Duplex in between not only is the impedance matched but I have a balanced signal that I can feed into my pre amp of choice. I no longer experience the annoying 60Hz noise. I plan on purchasing another one of these for my Roland XV-3080 soon. Love it!
