跟直流偏移劃清界線
瑞典 蘇霸 Supra 最新發表 LoRad MD01-16-BS 直流阻截器,專門針對寄生於巿電內,卻對音響器材構成深遠影響的直流偏移 (DC Offset)。直流偏移 (DC Offset) 的幕後懸兇,本是電氣設備因交流巿電正/負弦波出現不對稱,從而引發出來,並透過迴路進入供電系統。直流偏移問題並非新世代大發現,只是一直沒有太多音響設計師著眼於此。
磁飽和直接影響變壓器表現
眾所周知,絕大部影音裝置所使用的供電配套,都會配置直流內阻接近零水平的高質量變壓器,只要供電系統包含極低幅度的直流 (0.5V - 2V 水平) ,便足以令變壓器內部鐵片及經過絕緣處理的線芯繞組產生熱能,從而出現起震及引發哼聲,該等現像稱之為磁飽和。長期受到磁飽和影響的變壓器,不但會令工作效率持續下降,更會縮短壽命。
能阻截寄3.6V寄生直流
輸入插座為IEC 320 16A規格的Supra LoRad MD01-16-BS 直流阻截器,內藏自家研發高效率工作線路,峰值功率可達3,680W,能阻截寄生於巿電內高達3.6V水平直流,令器材得以回復最高工作效率,有助降低供電變壓器所產生的熱能。接駁方法亦非常簡單,用家只需透過串連方式接於牆蘇和電源排插之間便可。使用後播放背景將會變得更寧靜,動態再不會出現任何壓縮情況,輕易締造震耳欲聾,地動山搖戲劇性效果,所有音樂細節亦得以盡現眼前。
