Problem solver

Milosz, 31.08.2015
You wouldn't know how your A/D and D/A converters really sound until they match impedance of everything else you connect them to. This device helps me to connect my digital mixer's output with the signal attenuation to accommodate my consumer Denon amplifier. I used a pair of Sontronics attenuators before and they are more designed for microphone signals as they cut on high frequencies on line level signals. This device doesn't. I no longer hear any difference in the signal levels (and quality) when switching between different audio sources on my monitor amplifier and the noise/amp-hiss stays very low. Surprisingly, now all of my D/As sound nearly the same, with a very subtly audible difference, if any. Try Radial Engineering products. You'll be amazed at by how much you can improve your interfaces. And please don't try those cheap passive Neutrik solutions. I've done it and had to return them immediately. They lose connections, distort and not isolate. Radial won't let you down. Rock solid and clean product.

Top Ger t!

After I first tested the "CLEAN Box Pro" from the ART company, I decided to opt for the "Engineering Pro Iso Box" from Radial. In contrast to the ART box, the radial box offers a switchable ground lift, which immediately removed my existing hum. The sound is excellent as one knows it from Radial.

I would buy the device again at any time!
