由零開始了解平衡輸出

非平衡輸出

要了首先我們了解不平衡訊號傳輸的簡單原理,就是以正極傳送訊號.負極為零點(Ground),因為兩條導線電流量不同(不平衡),所以較容易吸引一些不必要的雜訊.使得長距離信號傳送品質下降,在耳機較常見的插頭為3.5mm / 6.35mm

平衡輸出

而平衡傳輸是以正相波形傳輸正相訊號,反相波形傳輸反相訊號,各自傳輸自己的訊號,,以兩個獨立訊號為一聲道,所以兩聲道就要四個獨立訊號了, 即使在長距離傳送時訊號不會衰減外,還能保持高傳真度傳輸,又因正反相是獨立兩個訊息傳送,不會因共同零點(Common ground)造成交擾或串擾,產生不必要的雜訊,在耳機較常見的插頭為 2.5mm / 4.4mm / 4-Pin XLR

Astell&Kern - AK70 MKII 高清音樂播放器

AK70 MKII 的平衡輸出提升至 4.0Vrms,輕鬆應付發燒玩家手上的各款高抗阻耳機。讓各位使用者不需要在簡易便攜和高輸出力之間作出抉擇,因為這台小巧的 AK70 MKII 已經能對應大部分需要使用。

Campfire - Andromeda

5單元設計再加上自家研發的Tuned Acoustic Expansion Chamber™ (TAEC)技術,帶出清澈自然的通透音色。可換線設計支援更換平衡輸出升級線

Crystal PEF28 2.5mm upgrade cable

全新的Crystal Cable Cantabile 採用18條銀-金導線, 而其絕緣層在抗敏感外, 更十分靈活貼耳, 確保配戴舒適。雙絞線設計令聲道分離度更佳, 而金屬接頭及包裝設計亦得到不錯的改良。

Fostex - TH-900 mkII (4-Pin XLR Version)

TH-900mk2繼承旗艦作TH-900的優點,並加入新的換線結構,在原裝的ET-H3.0N7UB非平衡耳機線外,用家也可選購ET-H3.0N7BL平衡線,以4-pin XLR插頭,連接到平衡輸出的耳機放大器。

Fostex - HP-A4BL 

HP-A4BL的平衡的耳擴設計除了令耳機不再有共用「地線」,以減低串擾外,更因使用了多一個負放大而令輸出力多了一倍。在配上Fostex專為自家產品研發的高階電容後,HP-A4BL的聲音極為傳神,高音通透開揚,低音爽脆有力,帶出細緻而自然的日本風。

ALO - Gold 16 Cable (4.4mm Version)

Gold 16共有16條導體,每條導體內含24絲無氧銅鍍金物料,再以纖維絕緣體作為軸心。這種設計大大減低了集膚效應,令全頻傳輸更為平均,聲音更為細膩順滑。更有多款插頭選擇。

理論總於歸理論,確實音響原是主觀的和無邊際的東西,不用擔心喔,我們為了大家預備好家用和便攜組合,方便大家駕臨荔技角陳列室作較全面比較

Gold 16 Cable
ALO's Finest IEM Cable: the peak in hi-fidelity + portability 16 Pure Gold Plated OFC Copper Conductors Signature ALO audio Reference Style Weave Each conductor is composed of 24 strands of individually gold plated OFC copper that has a fiber inner core. These 16 conductors create an IEM cable equalling 18awg overall. The gold 16 uses an FEP (Teflon) jacket that is oil and moisture resistant as well as being much tougher than PVC or PE jackets. The Gold 16 is woven with common mode geometry which creates a jacket-less low impedance effective shield. This enhances the overall depth and soundstage wideness of the overall cable's unique sound signature. The weave creates a cable that is extremely mechanically quite with low microphonics. The Gold 16 also is very soft and easy to bend and articulate. The combination of gold and copper creates a unique sound that emphasizes mid and low ease of listening and pairs well with balanced armature based IEMs.
HP-A4BL
Model HP-A4BL, designed being based on the current HP-A4, is an affordable USB DAC & Headphone amp offering balanced connection for headphones that is becoming more popular in the market.
