為了能讓電腦訊源的聲音表現能夠與類比器材具有相同的音樂性
一臺設計良好的線性電源就成為了電腦訊源不可或缺的硬體器材
這台線性電源的機箱外部尺寸為(含面板,腳墊,不含開關)
310mm長x120mm寬x130mm高,淨重近8公斤
全機使用8mm-10mm厚的鋁合金來達成良好的電磁屏蔽及諧振控制
不使用風扇散熱,機器也沒有震動
同時由於機箱的結構相當堅固
所以數台的線性電源可以相互堆疊使用而不會減損音質的表現
這台線性電源使用150VA(150W)的電源變壓器
最大可提供120W或10A的直流輸出
例如+12V/10A,+19V/6A,+5V/10A單組直流電源輸出
或是+12V/5A plus +5V/5A合計10A的雙組直流電源輸出
Today's PC base source become more and more extensive range of applications
In order to allow the PC base compared to analog equipment with the same musical
A well-designed linear power has become the indispensable PC base's hardware equipment
This linear power supply chassis outer dimensions (including panels, floor mats, non-switch)
310mm deep x120mm wide x130mm high, net weight near 8 kg
The machine use 8mm-10mm aluminum alloy to achieve good electromagnetic shielding and shock control
No cooling fan and no shake to the chassis
At the same time a very solid chassis structure let the linear power of the number of units
Could be stacked on top of each other use
And will not detract from the performance of the sound
This linear power use 150VA (150W) of power transformer
Maximum available DC output of 120W or 10A
Such as the +12 V/10A, +19 V/6A, +5 V/10A single DC power supply output
Or +12 V/5A plus the +5 V/5A total 10A Dual DC power supply output
為了讓穩壓電源在大電流輸出時仍能夠工作在很穩定的狀況下
所以必須要使用大容量的穩壓ic的輸出電容與負載端的退耦電容
大容量的電容能夠延長電容的壽命
也就是能讓這個線性電源能在長時間的使用下
不至於讓音質劣化
基本上大容量的電容不會讓聲音速度變慢
不正確的電路設計才是造成速度變慢的主因
A well-regulated power supply must be in large, small current output keep stable
To make the power supply in the high-current output is still able to work in very stable conditions
We need large output capacitor and the decoupling capacitors
Large-capacity capacitor could extend the life of the capacitor
That is, let the linear power under a long period of use
Will not let the sound quality deterioration
Basically large-capacity capacitor will not slow down the speed of sound
Incorrect circuit design is the main cause to slowdowns
往往是送電迴路與供電迴路的問題所導致
這也是我的線性電源必須使用搭棚的原因
自行搭棚可以設定最佳的迴路狀態
因而在負載端大電流的狀下
仍能維持回授網路保持很低的相移
這樣就會有很低的失真
Wrong transmission circuit and power supply circuit
Will be slow down the speed of sound in the case of large-capacity capacitor,
This is why I used scaffolding
Self-scaffolding can set the best state of the circuit
Will able to maintain the feedback network stay in low phase shift
Even large current thus the load end
This will let PSU keep very low distortion
十幾年前我就開始用無熔絲開關來取代保險絲
用無熔絲開關的優點很多
最近連作蚊量級管機的也開始拾人牙慧
開始用無熔絲開關來取代保險絲
雖然我已經用了銀錫
但為了保持良好的接觸來杜絕焊錫的不良影響
所以我焊接大面積的接點時
除了用恆溫烙鐵還要用尖嘴鉗將焊點及線材夾緊
這樣會在製作時會多花好幾倍的時間
這也是我的機器都必須裝很久的原因
使用XLR作為直流輸出
所以只要搭配不同的直流接頭
就可讓所有的週邊使用
This PSU used XLR for DC output
So change different DC connectors
This PSU will fit all devices
電源使用好的線材就變的重要了
因為雖然是號稱"電流"
但實際上能量在導體內是不流動的
而是經由電子與電洞的交換位置來達成能量的傳遞
好的線材有很低的電子干涉與繞射的現象
這樣才能有很好的音質
這台線性電源內部全部使用我自行開發的鐵氟龍鍍銀線材
這些自行開發的線材能讓在這台線性電源大電流輸出時
仍能保持穩壓電源保持中性均衡的聲音表現
同時為了確保這台線性電源的輸出性能
電源變壓器不再從市場購買
而是採用我自行繞製的變壓器
Have a good power supply circuit then you need good cord to maxium performance
Good wire will lower electronic interference and diffraction phenomena
So as to have good sound quality
This PSU used my self-developed Teflon silver plated wire for top sound quility
Meanwhile, in order to ensure that the output performance of the linear power
Power transformers are no longer buy from the market
Instead of using my self-winding transformer to control quility
機械震動會放大電子零件的電氣諧震
進而造成聲音的劣化
因而好的電源也還需要一個穩固的機殼
一台好的機器其實就是一連好的細節處理
有了好的平台
零件與電路對聲音的影響性就會降低
現在的HighEnd廠靠的就是如何優化的know how
沒有靠零件或電路就可揚名立萬的品牌
It has been confirmed through the measured
Mechanical vibration will gain electronic components's electrical harmonic shock
Thus resulting in the deterioration of the sound
Good power also need a solid chassis
One great PSU is actually a series of good details of the deal
With a good platform will reduce parts and circuit effect to the sound
The HighEnd audio depends on the know how in optimize to hardware & software
Not rely on parts or circuit
