Roma 117DC

三十多年來,我們始終致力於追求卓越的音訊技術。 Luigi
Lorenzon 先生及其團隊致力於打造能夠完美呈現音樂表演的音訊組件。
透過精心的設計、對頂級元件的精挑細選以及一絲不苟的製造工藝,我們打造出了我們認為同級別中無與倫比的線路前置放大器。

全新 ROMA117DC 真空管前級擴大機具有出色的音色平衡和細膩的音質還原,與 ROMA98DC 單聲道功率放大器堪稱絕配。 ROMA117DC
的設計與其他 ROMA 系列產品一脈相承,簡潔優雅。
對於最挑剔的音樂愛好者而言,這是一款極具音樂性的產品。

音頻電路採用兩級放大,內建兩對 6922/ECC88 電子管。
平衡輸入和反向輸入均由輸入管控制。
放大器的輸出級採用輸出變壓器。 ROMA117DC 具有
低輸出阻抗,因此連接功率放大器末級時,可靈活選擇各種互連線纜。
其頻率響應極為線性,-3dB 時可達 5Hz 至 40kHz。
燈絲和陽極的電源供應器均採用電子穩壓,穩壓精度優於 0.1%。

配備遙控器,可調整音量和選擇音源。
電子開關位於輸入介面附近,使訊號路徑極短,從而最大限度地減少聲道間的串擾。
音頻電路中僅使用精密電阻、金屬膜電容和聚丙烯電容。電子管的選擇也旨在確保音質,並最大限度地降低噪音和麥克風效應。
