Quloos QU02
New Isolation Technology
When both ends of the isolation are powered by the local pure power supply, we can hear the sound that is smoother, with cleaner background and more details. To effectively eliminate the ground loop noise introduced from the computer, the standard USB Bridge are equipped with complete ground isolation, such as INT204, Hydra Z+, Alpha, A.B.C, as well as some excellent USB Bridge in China. It’s obvious that a lot of efforts have been accumulated in this aspect.
The isolation design of QU02 is also unique. The CPU part of the USB Bridge, the audio output processing part and the clock part are completely isolated. The purpose is to isolate the interference caused by the computer, so that the sound is more pure and accurate. However, for almost all similar designs that adopted complete isolation, partial power supply of CPU of USB Bridge is by 5V power supply from USB inputted, so the sound will be greatly influenced by 5V power supply from USB inputted.
How about QU02? It directly abandoned 5V power supply from USB inputted and uses local pure power supply at both ends of isolation. Because both ends are designed with complete isolation, we made the isolation up to 3000V DC voltage before and after isolation, through Murata isolation power module. Through isolating the power supply, we realised the couplings, which not only realises the complete isolation, but also ensures that both ends are supplied with pure power supply with low internal resistance.
