M-12XLR 平衡線(第二代)

MPS M-12MK2全稱是M-12 Mark 2（第二代），方芯單晶銅螺旋覆蓋環形導體專利技術信號線，是MPS線材在2024年9月推出的，在第一代M-12音頻信號線基礎上改良開發的音頻信號線。

       M-12MK2是MPS線材採用獨有的專利技術絞線工藝生產，以單片寬高1mm×0.4mm的“6N方芯單晶銅”螺旋為基礎，加上7支0.4mm的6N單晶銅圓線填充入“6N方芯單晶銅”螺旋的空隙里，再次旋轉絞線成環形圓柱狀的銅芯線作为导体。線芯內部鑲嵌2支柔性PVC空管作為避震，讓線材結構緊致但聲音方面不缺乏空間感。線芯外層採用高強度鋁箔和高密度單晶銅網編織作為線材屏蔽，線材外皮採用日本進口編織避震網。
       M-12MK2單晶方芯銅的線芯由於沒有了中心點，大大減少了趨膚效應(skin effiect)的影響。 由於M-12MK2是多股導體結構，所以生產鄰近效應（Proximity Effect）當兩個或多個導體彼此靠近放置時，它們的電磁場會相互作用。M-12MK2將6N單晶方芯銅片至於導體中間旋轉，讓方芯銅導體產生的電磁場覆蓋裡面7支0.4mm單晶銅，減少鄰近效應（Proximity Effect）的產生，讓電流傳輸分布均勻。
       市面上普通圓形銅線導體的線材由於趨膚效應及鄰近效應影響，電流在銅線導體內傳輸不均衡，在HiFi音頻傳輸上表現就會導致聲音三頻不均衡，產生各種“聲音特點”。這個其實是導體內部傳輸不均衡的的表現。MPS品牌的M-12MK2在設計線材導體上，在物理學基礎上減少以上缺陷，讓聲音三頻均衡，結象清晰凝聚，高頻通透靈動，中頻柔和扎實、低頻厚實有彈性，整體線材達到一個平衡聲音的狀態。

MPS M-12MK2 full name is M-12 Mark 2 (second generation), square core single crystal copper spiral covered ring conductor patent technology signal cable, MPS cable launched in September 2024, improved on the first generation of M-12 audio signal cable development of audio signal cable.

M-12MK2 is MPS cable using a unique patented technology twisted process, based on a single piece of width and height 1mm*0.4mm "6N square core OCC" spiral, plus 7*0.4mm 6N OCC round core filled into the "6N square core OCC" spiral gap. The twisted copper core is rotated again to form a circular cylindrical copper core as a conductor. The core is inlaid with 2 flexible PVC air pipes as shock absorbers, so that the cable structure is tight but there is no lack of space in terms of sound. The outer layer of the cable core adopts high-strength aluminum foil and high-density occ mesh braid as the cable shield, and the cable skin adopts the braid shock absorber mesh imported from Japan.

The core of M-12MK2 square copper has no central point, which greatly reduces the influence of skin effiect. Because M-12MK2 is a multi-conductor structure, it produces the Proximity Effect when two or more conductors are placed close to each other, their electromagnetic fields interact. M-12MK2 rotates the 6N single crystal square core copper sheet in the middle of the conductor, so that the electromagnetic field generated by the square core copper conductor covers the seven 0.4mm single crystal copper inside, reducing the Proximity Effect and making the current transmission evenly distributed.

Due to the skin effect and proximity effect of the ordinary round copper core conductor, the current transmission in the copper wire conductor is unbalanced, and the performance in HiFi audio transmission will lead to the sound three-frequency imbalance, resulting in various "sound characteristics". This is actually a manifestation of unbalanced transmission within the conductor. MPS brand M-12MK2 in the design of wire conductor, reduce the above defects on the basis of physics, so that the sound three-frequency balance, the junction image is clear and condensed, the high frequency is transparent and smart, the medium frequency is soft and solid, the low frequency is thick and elastic, the overall wire achieves a balanced sound state.
