The d+ series "d+USB Class A" is a must-have USB audio device for DJs using Serato Scratch Live and TRAKTOR, music producers using USB interfaces, and anyone looking for the latest in PC audio. This is a USB 2.0 (HI-SPEED mode) certified cable that supports high-speed communication at a transmission speed of 480 Mbps. ■Key points of d+USB class A Class A uses 102SSC (25AWG signal, 21AWG power) cables for data transfer and bus power operation, ensuring high-speed, reliable data transmission and a stable power supply that preserves the definition and dynamics of the sound. A flat cable design avoids transmission loss, impedance changes, and capacitance changes caused by distortion inside the cable when it is bent. - The combination of TPE sheath, double shielding (braided 90% tin-plated copper wire and aluminum Mylar tape), and twisted pair structure protects the signal from external noise, digital noise, electromagnetic waves, etc. The connector is covered with aluminum, which provides better electrical characteristics and stable clock operation when bus-powered, resulting in superior sound quality for both recording and playback. The contacts are made of 24K gold-plated bronze alloy, which enhances durability and stability, maintaining excellent transmission performance for a long period of time. - This is a USB 2.0 (HI-SPEED mode) certified cable that supports high-speed communication at a transmission speed of 480 Mbps. d+USB Class A Specifications: Conductor: 102SSC (Signal 25AWG, Power 21AWG) Structure: Reverse concentric twisted flat cable Shield: Double shield structure (tin-plated wire + aluminum tape)・Insulator / Polyolefin・Sheath / Thermoplastic Elastomers・Connector type: USB Type A-USB Type B Terminals: 24K gold-plated bronze alloy Housing: PBT + Glass Fiber 30%・Outer cover / Aluminum
