Since DJing is a live performance, the stability of the equipment and the sound output are extremely important. Not only the performance of the equipment, but also using poor quality cables can lead to major problems such as interfaces not working or sound interruptions. Even if the sound doesn't completely cut out, there are times when the transmission is not good and the equipment is unstable, and warnings such as indicator lights showing the transmission status are often displayed.\u003cbr\u003e Regarding sound, there seems to be a misconception that the sound won't change since it's just data transfer. However, using cables and connectors with superior electrical characteristics can make a noticeable difference in sound quality. Furthermore, when using a bus-powered interface, the stability of the equipment and software is important, of course, but the audio clock is also affected by the stability of the power supply, so the importance of the USB cable in bus-powered operation increases.\u003cbr\u003e The d+USB series is a USB cable designed for next-generation sound systems, such as laptop DJing and music production using USB I\/O. It incorporates various features to provide the best possible environment for DJs and artists. Since data transfer is theoretically unaffected by cable-induced changes in bandwidth balance, the d+USB series, specifically designed for sound data use, delivers optimal results for sound production and listening using USB audio interfaces, regardless of genre. Its superior direct sound, stable transmission, and stylish industrial design make it a must-have item for next-generation DJs and creators.\u003cbr\u003e\u003cbr\u003e ■PC Audio: The world of PC audio is rapidly spreading as the next generation of listening style. USB transfer remains the main method of transmission for PC audio. The d+USB series boasts transmission performance that greatly contributes to high-end network audio.\u003cbr\u003e Designed with the utmost precision for professionals such as musicians, DJs, and engineers, this cable delivers optimal results in listening environments using USB-DACs, regardless of genre or user preference.\u003cbr\u003e For real-time data transmission, accurate data transmission is paramount. Even with cables, errors can occur due to various factors such as electromagnetic waves, noise, impedance adjustment, and electrical signal attenuation, all of which affect performance.\u003cbr\u003e It is also widely known that the sound of digital audio changes significantly depending on the audio clock. Since the audio clock is also affected by the stability of the power supply, the USB cable, which uses power lines, is a surprisingly important factor.\u003cbr\u003e Based on fundamental concepts in data transfer, we applied and implemented approaches from analog environments, such as noise reduction and superior electrical characteristics. We considered crucial combinations in cable design, selecting the optimal components for everything from cable structure, conductor type, conductor diameter, insulator, shielding, sheath, and plug contacts. This minimizes losses due to various factors, ensures stable power supply, and delivers high-quality sound.\u003cbr\u003e The d+ series also prioritizes industrial design, providing a smart and stylish presence to wiring that would otherwise appear cluttered.\u003cbr\u003e Combining quality and design, the d+USB series unlocks the potential of devices such as USB-DACs, further expanding the world of PC audio and delivering true sound to your ears.\u003cbr\u003e\u003cbr\u003e ■ Architecture and Analog Elements in Transmission It is widely known that the sound in a digital environment is greatly influenced by the quality of the AD\/DA converters and the jitter accuracy of the audio clock. However, in reality, there are other factors that change the sound, and just like in analog, it is often affected by electromagnetic waves and noise, which can introduce noise, as well as by applications, drivers, and the hardware parts of the PC itself.\u003cbr\u003e Even in high-speed serial bus transfers, data transfer is affected by the software system configuration, the connector, the circuit board pattern, the surrounding environment of the chip, and analog components such as cables.\u003cbr\u003e The d+USB series was designed to ensure smooth, loss-free data transmission by understanding the role of cables within the overall system configuration, encompassing both software and hardware.\u003cbr\u003e In digital signal transmission, the key is to deliver the ON\/OFF digital signal waveform from the transmitter to the receiver in as little state as possible. The cable's role is solely to transmit data, so thoroughly reducing losses due to various factors is crucial for minimizing unnecessary problems and achieving high-quality sound. Furthermore, since the signal flowing through the cable is an electrical signal, even if digital, an analog approach that considers electrical characteristics is also important. The d+USB series efficiently protects the signal from external and internal noise, as well as electromagnetic waves often generated by PCs, and employs an approach that minimizes electrical signal attenuation by considering conductivity and dielectric constant. By minimizing cable loss, it achieves the true, three-dimensional sound.\u003cbr\u003e\u003cbr\u003e ■Impedance Adjustment: Designed with maximum consideration for the characteristic impedance of the cable, which is crucial for digital transmission, and precise pitch adjustment is performed using advanced technology. To send a stable signal, it is necessary to control the impedance, so distance, thickness, distance between cables, twisting, etc. must be considered. Because d+USB has precise impedance matching, it has a clean electrical signal waveform, suppresses reflection noise without causing termination reflections, and achieves accurate transmission and excellent stability.\u003cbr\u003e\u003cbr\u003e ■ Aiming for reliable high-speed transmission through carefully selected conductors, the Class B conductor uses \"Silver-Coated OFC High-Purity Oxygen-Free Copper,\" which is coated with silver, resulting in a pure resistance approximately 5% lower than that of copper. Furthermore, Class A and Class S also take power lines into consideration. Class S uses PCOCC [Pure Crystal Ohno Continuous Casting Process], which theoretically eliminates crystal grain boundaries in the signal transmission direction. Class A, following the discontinuation of PCOCC production, uses Oyaide's precision conductor 102SSC, which achieves 102.3% IACS through advanced manufacturing technology and control. These superior conductors ensure reliable transmission in data transfer and stable power supply. In addition, the conductor diameter of Class S is set to AWG22\/AWG18, double the normal size. This further reduces electrical resistance and enables powerful transmission.\u003cbr\u003e\u003cbr\u003e ▼Product Specifications Cable: USB 2.0 cable (HI-SPEED mode)\u003cbr\u003e Transfer speed: Maximum transfer speed 480Mbps\u003cbr\u003e Conductor: 102SSC (Signal 25AWG, Power 21AWG)\u003cbr\u003e Structure: Reverse concentric stranded flat cable Shielding: Double shielded structure (tin-plated wire + aluminum tape)\u003cbr\u003e Insulator: Polyolefin\u003cbr\u003e Sheath: Thermoplastic Elastomers\u003cbr\u003e Connector type: USB Type A - USB Type B\u003cbr\u003e Terminals: 24K gold-plated bronze alloy; Housing: PBT + 30% Glass Fiber\u003cbr\u003e Outer cover: Aluminum; Solder: Oyaide SS-47 (for audio applications)","brand":"Oyaide","offers":[{"title":"Default Title","offer_id":44584677245041,"sku":"381767","price":53.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/4173\/0673\/files\/381767_01.jpg?v=1789699394","url":"https:\/\/global.ikebe-gakki.com\/ko\/products\/381767","provider":"Ikebe Musical Instruments Store","version":"1.0","type":"link"}
