The architecture under digital environment
Although the fact that the sound quality under the digital environment is influenced by the quality of AD/DA converter and jitter accuracy of audio clock is well-known, there are other factors that actually change the sound such as noise contamination or matching with the appreciation, driver, and PC hardware.
As for the high-performance serial bus, it is influenced by the system architecture of software, connectors and circuit patterns, ICs and cables. In addition, isochronous transfer that is applied in many USB audio I/Os have no error correction despite of carrying a huge amount of information at the same time.
"d+ USB series" was designed for smooth and lossless data transmission in both of the software and hardware system structure. The important thing in the digital signal transmission is passing the signals from sending side to receiving side as natural as possible. Because the signal flows in a cable is, even if it is digital, the electric signal, and the analog-like approach considering the electric property would be very portant and effective.
Neo took an approach to protect the signal from external and internal noise by electro-magnetic wave and control its electric conductivity and permittivity.
We carefully made an adjustment impedance matching by advanced technology by considering pitch, diameter, and strand of conductors. Consequently, we achieved accurate data transmission and excellent stability with attenuation of terminal reflection wave.
For class B, in order to transmit serial bus at hi-speed, we applied the silver coated OFC which resistance is 5% lower than copper conductor. For class A and class S, considering bus-powered, we selected the hi-quality PCOCC pure copper conductor.
Because the signal flows on the surface by skin effect, the PCOCC which has no grain boundary and flat surface is very effective for even data transmission. Therefore, it actualizes the stable data transmission and power supply. In addition, the conductor diameter of the class S is set to AWG22/AWG18 which is twice as thick as the regular cable for powerful sound reproduction.
Flat design architecture
The flat designed cable prevents the signal loss caused by cable bend, change of impedance and electrostatic capacitance. And it protect signal from external/internal noise and electro-magnetic wave by combination of TPE outer sheath, double-shielding, and twist-pair structure.
The contacts of the USB connectors are made of bronze alloy with selected combination plating for each class. For class S, it is a combination of platinum and rhodium. For class A, it is a combination of silver and rhodium. And for class B, it is gold plating. Each plating enhances durability and stability of the connectors.
USB2.0 (HI-SPEED) compliant.
