The biggest cause of sound quality deterioration in PC audio is the huge amount of noise generated by the PC. PC noise flows into audio equipment not only from the power supply of the PC but also through the signal line and power supply line of the USB cable.
In other words, no matter how much the power supply of the PC is isolated by a noise cut transformer or the like, even if the PC itself is battery-powered, noise can flow into the audio equipment as much as possible through the USB cable, which significantly deteriorates the quality of the audio equipment. It has been done.
Cut PC noise 100%!
RUI-1 uses an IC made by Analog Devices, which was developed to prevent malfunctions of medical devices, as the USB signal line, and the USB power supply line uses an IC that has a higher noise removal effect than the genuine analog device, and PC noise. We have succeeded in reducing both the USB signal line and the power supply line to the nano level, that is, cutting almost 100%.
At present, there is no other way to completely cut PC noise, and the effect of improving sound quality by completely avoiding the effects of PC noise is truly enormous.
The S / N ratio has improved dramatically, and you should definitely enjoy the pleasure of creating a high-quality sound image with no distortion in the infinitely transparent sound field.
Our USB cable USB-1.0SP can also be used
Since the output side of RUI-1 has two A terminals, it is possible to use a USB cable with separate A terminals such as our USB-1.0SP.
RUI-1 is extremely effective even when using a normal USB cable, but if you use USB-1.0SP or USB-1.0PL together, the signal line in the USB cable will interfere with the power line. Since it will not be received, it will be possible to further improve the sound quality.
The cable of RUI-1 itself can also be separated from the A terminal.
As for the cable connected to the PC at the tip of RUI-1, it is possible to custom-order the A terminal to be separated like our USB cable USB-1.0SP.
By separating the signal line and power supply line from the PC side by using two A terminals, interference at the USB terminal part is further eliminated, the S / N ratio is further improved, distortion and noise are reduced, and sound energy. It is possible to dramatically improve the sound quality, such as increasing the feeling and thickness.
Noise / vibration control processing on the RUI-1 main unit
RUI-1 uses a natural crystal washer for the board mounting part, and has vibration damping measures for the internal board.
In addition, a green carborundum that converts noise into heat energy and eliminates it is placed inside the main body case to suppress noise generated from the RUI-1 board itself.
With these vibration control measures and noise countermeasures, RUI-1 can fully demonstrate the PC noise removal effect, and by using RUI-1, not only the PC noise removal effect but also the texture and tone can be improved. Is possible.
Scheduled to upgrade to USB 2.0
Please note that RUI-1 is not compatible with devices that use USB 2.0.
As soon as a USB 2.0 compatible IC is developed for USB 2.0, we plan to support version upgrade.
However, even if the PC side is USB 2.0, if the DA converter side is USB 1.1 or USB 1.0 specification, transmission up to 24bit / 96khz is possible, and the effect of cutting 100% PC noise is truly enormous ( Please note that if the DA converter side is USB 2.0 specification, recognition itself will not be possible.)
High resolution software such as 176.4kHz, 192kHz , DSD and download sound sources are still few, and the original performance in an environment with a lot of PC noise. It is also not possible to demonstrate.
When PC noise is completely cut with RUI-1, it is possible to achieve quality that is as good as high resolution not only for 96kHz but also for 16bit / 44.1kHz sound sources, which is the conventional CD standard.
