HD-400是MPS於2024年上半年發佈的一款全新4芯信號線纜，主材質採用99.9999%單晶銅鍍銀（OCCS）製成，造就其超高的傳輸速度及無與倫比的分析力。HD-400採用世界通用的USB接線分類，紅、黑、綠、白四芯結構，綠+白線單獨鋁箔屏蔽之後，再四芯公用鋁箔+銅網屏蔽，超高的屏蔽率讓用於信號線纜傳輸更無損、無雜訊，無論用於數碼信號傳輸或是模擬信號傳輸、均有十分出色的表現。
聲音效果方面，得益於單晶銅鍍銀（OCCS）材質的超高解析力和明亮但不尖銳的優秀的高頻效果表現，中頻聲音柔和潤澤、女聲之綿密的臨場感，低配速度快而彈性和下潛十足。整體聲音背景乾淨靜謐，三頻高解析，適用於需要增加解析力和亮度、速度之設備系統使用。
HD-400可用於USB數碼線纜、RCA線纜、XLR線纜等線纜的製作使用
線纜內芯結構：0.25mm²*4/23AWG*4
線纜直徑OD: 7mm±0.5mm
HD-400 is a brand new 4-core signal cable released by MPS in the first half of 2024. The main material is 99.9999% single crystal copper silver plated (OCCS), which creates its ultra-high transmission speed and unparalleled analytical power. The HD-400 adopts the world's universal USB wiring classification, with a red, black, green, and white four core structure. After the green and white wires are individually shielded with aluminum foil, they are then shielded with a four core common aluminum foil and copper mesh. The ultra-high shielding rate makes it more non-destructive and noise free when used for signal cable transmission. Whether used for digital signal transmission or analog signal transmission, it has excellent performance.
In terms of sound effect, thanks to the ultra-high resolution of single crystal copper silver plated (OCCS) material and the excellent high-frequency performance of bright but not sharp, the mid frequency sound is soft and smooth, and the dense presence of female voice is felt. The low configuration speed is fast, elastic, and full of diving. The overall sound background is clean and quiet, with high resolution in three frequencies, suitable for use in equipment systems that require increased resolution, brightness, and speed.
HD-400 can be used for the production and use of USB digital cables, RCA cables, XLR cables, and other cables
Cable core structure: 0.25mm ²* 4/23AWG * 4
