dCS Vivaldi Upsampler with USB interface 升頻器

dCS Vivaldi新旗艦產品重新定義最先進的數位播放系統,該產品的設計呈現我們”’絕不妥協的顛峰之作,無人能敵的家庭式音樂系統,更締造了未來數位音響最新標竿。

Vivaldi Upsampler 被設計為數位音響中的集大成者,將帶領您體驗前所未聞的音質表現。

Vivaldi Upsampler作為數位/數位轉換器,可處理音樂任何的數位訊源,並將原始的取樣頻率轉換成高解析度之DXD(24位元信息(bit data)或352.8或384 kS/s),DSD(1位元信息在2.822或3.07MS/s)抑或標準高解像度的PCM(24位元信息升至24/192 kS/s)。Vivaldi Upsampler證明其產生的效果令人振奮:更加明亮、立體、清晰、自然地表現完美的音質。

Vivaldi Upsampler的特色是金屬電路的連接裝置,可串流電腦或由UPnP™儲存在網絡中,高解析度的音樂檔案。Vivaldi Upsampler中附加的非同步USB輸入端子也可以直接與電腦(PC)連接並支援上升至192kS/s的音樂以及DSD格式。USB介面以非同步的USB模式運作,讓Vivaldi Upsampler不受電腦中典型噪訊時鐘的基時誤差的影響。

Apple認證授權Vivaldi Upsampler可支援iPod/iPhone-store數位媒體,亦能支援USB輸入方式,經由iPod/iPhone內部DAC確保最完美的表現。

一系列可供個別選取的數位輸入端子(RJ45, USB, AES, SPDIF, SDIF-2, Toslink)造就Vivaldi Upsampler功能強大的器材性能,讓CD Player中的Red Book CD或是多媒體播放器中的高解析度音響表現更出色。

dCS不僅是數位音響外部時鐘的使用先驅,更改良多層級鎖相環(PLL, Phase-Locked-Loop)系統,設立世界級的精確標準,使我們能在未來的音響系統中輕鬆掌控時基誤差的干擾。

想輕鬆使用這款多功能的產品,使用者僅需選擇使用全彩的前板選單、Vivaldi Controller App或高階的dCS遙控器便能做到。Vivaldi Controller App也能讓使用者改變DAC的輸入和聲音,更佳簡化了控制的流程。

dCS軟體式思維的操作手法,讓我們不論是增添新功能,安裝提升聲音表現或適應數位格式的軟體,使用起Vivaldi Upsampler升級軟體都能更快上手。

身為Vivaldi 數位音響播放系統的功臣之一,Vivaldi Upsampler使得音質表現更趨於自然流露的真實感。
