 CT1 級進式音量控制器
DESCRIPTION 說明
丹麥音響關係公司(Danish Audio connect,DACT)的CT1是高品質24段階進音量衰減器
或是當今您可能擁有的高品質擴大機 以及其他音響器材使用的音量控制器.
目前供應的是立體兩聲道版本, 它有兩個個別的印刷線路板, 按置在兩個碟片旋轉選擇器上.
CT1串連式電阻的網路, 包含有每一聲道23個無感抗的低雜訊SMD晶片金屬氧化薄膜電阻.
PC基板的佈線方式和精選的晶片電阻, 設計能減少信號路徑到最短長度(專利申請中).
所有的接點和PC基板電路線徑, 都是鍍金表面以確使長時間的使用信賴度.
採用瑞士製精密鍍金旋轉選擇器, 先接然後切斷型(make-before-break).
CTl是為最高的聲音品質, 精確和信賴來設計的產品.
標準Stereo立 體- 阻抗值有 10K, 50K, 100K & 250KΩ.
Mono單聲- 阻值有10K, 50K, 100K & 250KΩ.
CT2 級進式音量控制器
(CT1的平價型號, 價格更低, 效果維持或甚至理論上更好)
標準Stereo立體- 阻抗值有 10K, 50K, 100K, 250K & 500KΩ.
尺寸: 25 x
40mm, 67mm (L)

RIAA放大模組,詳細資料
來自EnjoyTheMusic.com的產品評論, 部份內文如下;
“Second, an admission (after the confession), if you had not already guessed. This is the finest phono-stage I have ever had in my system, bar-none. Less cuddly than my Ear834p, and more transparent and detailed than the Musical Fidelity XLPS2 that I also put it up against, it is basically, in a league of its own.”
最新的四/五月2001美國The Absolute Sound絕對音響雜誌, 由Dan Sweeney主筆推薦
DACT多種產品評論,
他使用完全以DACT為基礎的放大器系列來聆聽見證;
CT100 phono stage, the CT101 line
stage,
兩個mono CT1 stepped attenuators and a
CT3-5-4 輸入選擇開關.
以下為Dan Sweeney寫了些什麼的例子之一:
“ I don't know if the DACT preamp is
the best solid-state example of the category on the market, but I'd
like to see anything that touches it for under seven or eight grand.”
And . . . . . ” So why would you do
this? Well, I own three phono sections: an old Stax SR-14; an older
Sumiko; and a Boulder L3AE.
The latter is far superior to the first
two, though it lacks flexibility, and the Dact is superior to it. The
L3AE,
available on special order, is about $3,700, while the Dact assemblage
under
review costs approximately $2,000. These facts say a great deal for
it's
design integrity.” . . . . . .
And . . . . . “ Similarly, tape hiss
assumes The Dact utterly lacks the usual solid-state blemishes: grain;
hardness
in the treble; an overall fatiguing quality. I normally prefer tube
phono
stages for their sweetness and musicality, but I don't know of one I'd
substitute for this.
The Dact doesn't sound like a tube
circuit but then, it doesn't sound like much of anything. Other than
conveying an incredible sense of transparency, wide dynamics, and
ultra-low noise, it doesn't seem to impart a signature of it's own and
isn't that what we're after?”
