There's no off-the-shelf USB isolation chip which supports high speed. Your DAC has a PSRR of like > 90dB which you can subtract down from these values. That is, what the power supply of your DAC will see. See attached plot ( ) showing measured output noise. We managed to keep the noise as low as possible. While developing the isolator, we took special attention to the noise coming from its data and power lines. All common noise from the computer is being ripped by the isolation barrier. all power regulators are linear, there is no common noise coming from the isolator. a complete new and absolutely silent ground and 2. There is absolutely no contact with any computer signal.Īs there is 1. Using galvanic isolation is more like wireless. I don't want to say anything bad about this but nobody would ever use something like that in the industry to get better SNR or the like. The *********** seems to be audiophile stuff. Would your isolator make *********** redundant? In other words, would the galvanic isolation filter out common-mode noise? Does the isolator deal with common mode noise? I currently have an *********** USB Filter which reduces the common-mode noise in USB cable. Of course, the industrial version has even better connectors and all parts are certified for extended temperature and, finally, every unit has to pass an isolation test with 2,500 volts for some seconds. Even in a classical ground loop situation, there are no potential differences that would require higher isolation to get rid of the loop. The 1kV (standard) version will be sufficient for your application. Would the standard version of isolator meet my needs? In other words, the industrial version could be an over kill for me. We have also some pro-audio and pro-video (4k/high frame rate) customers and they successfully solved noise coupling issues completely. ![]() Resulting sound quality improvement is the effect of breaking all the noise coming from the host computer.Īs this is a true industrial product, we focus primarly professional applications like automation systems, medical and research labs (even the computer manufacturer with the fruit has one).īut of course, as this product is designed for low noise (research labs need this to gain dynamic range vom nanovolts to kilovolts) and perfect signal integrity, we understand your demand. The intended purpose is complete isolation of both data and power lines. ![]() Would the isolator improve the sound quality? With his permission, I will quote this here again to the public. There are some audio-specific things I discussed already with tubesound by mail. Our accounting says that he has serial no #1 of mid September and we made some changes to the firmware since then - maybe this or maybe your thoughts about power consumption of his DAC caused the issue. ![]() Indeed, we were not aware of the post by Phasure and didn't get any direct feedback by him so far. My name is Daniel and I am CEO of Intona Technology, Germany and also the head developer of the USB 2.0 Hi-Speed Isolator. Daniel from Intona answers some questions on his high speed USB isolator. ![]()
