「轉載」KRELL的兩款新產品發佈

h2189

KRELL近日在CES 2012展會發佈了兩款新產品，分別是S550I合併機和PNANTOM III前級放大器。
Pnantom III
新增了一個可選的數字輸入埠（AES/EBU）和一個耳機輸入介面，具備了ＤＡＣ解碼和耳機放大器功能。DAC解碼最高支持24-bit/192KHz音訊，而耳機放大電路作為一台獨立的通道併入主放大電路，使耳機的音質達到前所未有的水準。Pnantom III採用了真正的雙聲道設計，左、右聲道勻採用完全獨立的電源和線路板，為每個聲道提供穩固澎湃的動力和杜絕信號干擾。
S550i
是一款集成了iPod基座的合併機，具備了單端（RCA）和平衡（XLR）輸入介面，RS-232連接，前級放大部份參照了Pnantom III的電路設計，功率輸出使用1750V/A環形火牛和68000μF電容量，為每聲道提供275W（８Ω）、550W(4Ω)的動力，性能甚為強勁

Krell.....Phantom III Pre Amplifier

Krell全新前置放大器Phantom III,定位於高級市場。這款新版前置放大器延續了旗艦的眾多精華,並新增加了可選的模組插卡功能,可以增加數碼模組或耳機模組,其中數位模組讓Phantom III增加AES/EBU、同軸、光纖數位輸入等數碼流輸入介面,數位模組支援高精度的24 bit/192kHz的LPCM解碼能力,基於ESS Sabre DAC高品質解碼晶片,類比放大部分為分立全平衡電路,配合Krell的低電平線性,實現每一個音樂細節完美重現。

Phantom III電源部分採用95VA大型變壓器和40,000μF的濾波電容,提供充足的電源供應,滿足大動態音樂需求的快速反應能力。而且為了回應環保的要求,具有先進的待機模式可減少電力消耗低至2W。 Krell Phantom III使用上旗艦同樣的無負反饋結構的全平衡電路,這個電路是專門為旗艦身歷聲前級而開發的先進訊號電路。該電路是基於無負反饋結構的全平衡技術(電流增益模擬線路),提升訊號重整的準確度,電流模式具有700 kHz頻寬,開環失真小於0.003%,從而能確保真實、準確的還原出HD高清環繞格式的最精確細節。音量控制部分採用了全新開發的全平衡、寬頻寬的階梯電阻步進控制,實現良好的音響性能。配備旗艦級的耳機放大電路,為用家提供頂級的耳機驅動能力。  
Phantom III配備有CAST(Current Audio Signal Transmission)技術,即電流信號傳輸技術,是Krell為模擬器材之間的連接提供最精確訊號傳送而開發的專利技術。它借助電流訊號音質純度高的優點,來消除以電壓形式傳送信號時,由音響連線間交互影響而導致的信號損失。
Phantom III主機殼提供銀色或黑色漆面。

而家 Krell都Made in China. 不知D 質素如何.但价錢就一定不低.
現在美國品牌仍Made in USA的.眞是越來越少.

totally agreed with 3樓 .
