MA-PB75A-8 STUDIO Isolation power block

讓MA靜神以成熟、高層次的隔離抑振電箱，匯聚電源能量之庫，展現全頻寬的分流性能

成功的電箱要件，不外乎擁有完整的設計、縝密的佈局、執行優質高效的能量分配，並快速釋放電位差，讓電能以充沛且快速的電路前進。MA靜神一直追求著自我的極限，旗下隔離抑振電箱經歷了數代的演進，採以最完善、完整的線路佈局，加上精良且特殊的零組件，將入戶電能作第一次的醇化處理。

MA靜神的隔離抑振電箱，內外部件全都採用訂製組件，箱體採用厚鐵鍍鋅、並覆以特殊高溫烤漆處理，給予隔磁、抑振、穩固的基石，內部斷路器採用台灣大廠的「客製」無熔絲閘，從外觀看來與一般市售相仿，常被質疑為何不用國外知名的品牌，但這樣的崇洋心結，不僅看低台廠，也完全低估了MA靜神的嚴苛標準；與我們合作的台廠，其技術與性能都可依需求要求、且支援度高，再複雜的工序都能幫忙搞定，並強化高規結構製程封裝，如無熔絲的核心介電，在持續不斷的大電流經過絕緣材時，能夠完全隔絕電磁輻射與弱電的干擾，確保高介電值、耐大電流電壓的高效性能，完整傳輸極大化的電能頻寬，這些都是現成市售品所無法相比的。MA靜神歷經長時間的開發研究，專注於精確的音響電源這領域，將別人做不到的極寬頻，透過「MA靜神電源系統」重新展現，這是市面上常見的拼裝電源所到達不了的，而MA靜神堅持關鍵的每個環節都不能錯放，最終才能擁有豐潤、飽滿、充沛、純淨的寬頻電能。此外，L相（火線）、N相（水線）的分閘不用一般傳統的電源線，採用特別訂製的高階銅板，經CNC切型後、處以細緻打磨，最後鍍上電子級貴金屬，保持最佳的金屬物理條件，其耐高電壓、高電流、高速傳導的特性，與半永久性的穩定條件，展現出極為優異的電源傳輸性能，表現出不凡的全方位導電能力。

而同樣工法也用在G相（地線）上，搭配上PG-16接地匯流排，讓電位差能更加快速的釋放。箱內更為了隔離與抑振，特別加上金屬隔離板與增加強化結構點，讓全頻寬電源在安定穩固的機箱內流暢地分流出去，任何會影響電源品質的小細節都不放過；玩家還能選購MA靜神的「Basic MKⅡ or Studio MKⅡ 超級接地器」、「M-460 複合地迴接地板」，更能讓接地的性能翻倍躍進，這同時也是淨化電源的重要核心之一，我們強烈建議「進入室電的第一步」千萬不容小覷，別讓拼裝車在一開始就虛化了電源能量，選擇MA靜神電源系統，將是您翻轉平凡電源的第一步，極致音響電源的無限可能從此開始。

MA 靜神 MA-PB75A-8 STUDIO
75–100A Single-Phase 8-Output Isolation & Damping Power Block
An Elevated Reservoir of Power—Commanding Full-Bandwidth Precision and Absolute Control

For the audiophile system to reach its peak potential, it must begin with uncompromised power. The MA-PB75A-8 STUDIO represents the pinnacle of isolation and damping power blocks from MA 靜神—a mature, fully evolved system core that channels and purifies incoming energy with commanding bandwidth and stability.

Engineered for Total Energy Control

The essential qualities of a high-performance power block lie in its comprehensive design, meticulous internal layout, precision energy routing, and the ability to dissipate potential differences swiftly, allowing power to travel with speed, fullness, and efficiency.

MA 靜神 has pushed the limits across multiple generations of development, continuously refining circuit topology and applying rare, bespoke components. The incoming household current undergoes its first stage of refinement through an expertly balanced and uniquely structured internal power path.

The STUDIO model features custom components throughout—starting with a thick galvanized steel chassis finished in a special high-temperature industrial coating that provides excellent EMI shielding, vibration suppression, and mechanical stability. Internally, MA 靜神 collaborates with a leading Taiwanese industrial partner to deliver a custom, fuse-less circuit breaker system. Though modest in appearance, these breakers surpass international brands in technical performance, dielectric strength, and manufacturing consistency.

Unlike typical off-the-shelf breakers, these systems are tailored to meet MA 靜神’s extreme standards, including high dielectric integrity, resistance to electromagnetic emissions, and isolation from signal noise, even under sustained high-current conditions. This ensures broadband energy transmission that is unrivaled in clarity and bandwidth.

Precision Conductors & Premium Materials

Both the L (live) and N (neutral) phases utilize custom-machined high-purity copper busbars, processed through precision CNC cutting, ultra-fine polishing, and electronic-grade precious metal plating. This maintains peak physical and conductive properties across high voltage, high current, and high-speed conditions, while also guaranteeing semi-permanent operational stability. The result is full-spectrum conductivity with exceptional resolution, dynamics, and balance.

The G (ground) phase receives the same treatment, complemented by a PG-16 grounding busbar that rapidly balances potential differences. Internally, metal shielding plates and reinforced structural braces are added to reduce vibration and isolate paths, ensuring that broadband power is distributed with clarity and confidence.

Beyond the Block—Expandable Grounding Architecture

Audiophiles seeking even more robust grounding performance can integrate the MA 靜神 Basic MKⅡ or Studio MKⅡ Super Grounding Devices, or the M-460 Composite Ground Loop Base. These options significantly elevate grounding efficiency—often doubling its effectiveness—and form a crucial part of advanced power purification. We strongly emphasize: “The first step of power entering your system must never be compromised.” Don't dilute your energy foundation with cobbled-together solutions. Choose MA 靜神, and take the first true step into ultimate power refinement. From here, the possibilities of sound are limitless.
