As for "STC-USB2.0R3D", the Zonotone USB cable "6N / USB Grandio2" used in the previous version "STC-USB2.0R2D" has been discontinued, and the successor model "Grandio USB-2.0" has been released. In response to that, the updated model. With the higher performance of the cable, it aims for a higher quality and vivid reproduction presence while maintaining the natural texture and wide range feeling.

In addition, the aluminum block cutting process of the treatment unit has been made more accurate. In addition to precision polishing, the surface treatment method also protects the surface of acrylic coating, improving environmental resistance and surface deterioration resistance. The internal structure is completely the same on both the target / host side, such as the microstrip line wiring pattern, separation of the bass line from the ground plane, and floating from the external shield of the circuit board.

From this time, in addition to the USB A-B terminal model, we have a lineup of USB C-B terminal models that have been requested a lot. It is said that it has made it possible to respond to various user groups.

"CTU-06b" is a single treatment unit that improves the transmission waveform and stabilizes the transmission by sandwiching it between the coaxial output lines of digital audio equipment, and can improve the sound quality. Requires DC5V as an external power supply.

Since it is equipped with a 1: 1 pulse transformer dedicated to digital audio and a receive buffer circuit that uses the inverter "IC74HCU04", it stably receives and shapes the waveform even if there is disturbance or waveform disturbance or fluctuation on the output side. That is. In addition, the S / PDIF output section is equipped with a Schmitt trigger circuit. Using the strong feedback of the same circuit, it suppresses fluctuations near the threshold value and sends out an accurate pulse waveform.

In addition, it is equipped with a common mode noise filter with DC5V input. It is said that a clean and stable power supply is supplied to the circuit by suppressing the switching noise of the DC power supply. It is necessary to connect an external power supply, but the included 1.5m power cable is equipped with a USB-A input connector, so it can be used with USB bus power. If you prepare an adapter for mobile devices, you can connect it to a normal outlet.

Two types with RCA connector / BNC connector are available, and a model with a 5N sterling silver 0.5m coaxial cable is also available.
