DESIGN NAME: sNH-10G
PRIMARY FUNCTION: Audio Grade Network Switch
INSPIRATION: Most decent audio system is related with network, so we call it as "Network audio system". By network circumstances in the audio system, the sound is noticeably effected to the quality of sound. So we had developed the audio grade network switch by our own technology applying the custom designed ultra low phase noise oscillation circuit, LAN signal isolation technology and so on to present the best sound quality.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: The sNH-10G can be titled under the world first audio grade network switch. The design is focusing to improve sound quality for every network audio system. Specilally by syncronizing 10MHz master clock signal to the sNH-10G externally, the sound quality could reach its climax. The custom designed ultra low phase noise oscillation circuit and isolated differential clock signal distribution have been applied and LAN filtering, LAN isolation, LAN insulation are equipped as the standard features.
Specially the front, top and rear side air bents are designed to reveal the emotional appeals toward audio equipements by embodying audio signals and melody naturally.
And the unique design, which has the wider topside than the underside, emphasizes the masculine aspect of the most audiophiles as a male and also is designed to blend feminine delicacy by planting the edges on the corner and lines of the sides of sNH-10G .
OPERATION / FLOW / INTERACTION: How to use the sNH-10G is just simple as a normal network switch, it should be connected to after the router and then connected to the network audio device by Ethernet cables. By using the sNH-10G in the middle of the router and the network audio device like a server or a player, noise came from the lan port and Ethernet cables would be removed and it helps to improve sound quality for the network audio system.
PROJECT DURATION AND LOCATION: The project started in 2018 in South Korea and finished in June 2018, and was exhibited for the first time in the world in May 2018 at the world best audio show in Munich.

RESEARCH ABSTRACT: Nowdays people get interested in the importance of network enviroment, because there are noticeable sound differences and improvement made by the good network enviroment in audio system. Originally the sNH-10G is developed for everyone who runs the audio system over Ethernet, but the PC is one of the basic device which operates via wired Ethernet connection and every network device which has LAN ports can work with sNH-10G. So the demand of sNH-10G is not only limited to the audio field, but anyone would like to have much stable network enviroment and hi end netowrk system, the sNH-10G would fit to the reqeust.
CHALLENGE: The sNH-10G is not only an audio electronics but also a network devices, so it should have revealed the differences of how and why the audio grade network swtich should be required.
It is related with the matter of how to present the sole characteresistcs of sNH-10G for everyone whom uses the network switch. And by presenting the high quality of sound finally, the specialty of sNH-10G could be revealed.
