Rogue Audio Medusa
後級內部公開
Medusa是D類晶體與真空管混合的後級,有著真空管豐富的音樂性及晶體的動態。Medusa的設計不是單純的直接在D類放大前加上真空管線路,使用的是Rogue Audio獨家的tubeD™線路架構,實際將兩者結合在一起。待機時晶體放大部份仍有提供電力,真空管則是較緩慢的啟用,以保護真空管。Medusa輸出功率為200W(8 Ohms), 400W (4 Ohms)。
打開內部就可看到兩顆一大一小的環型變壓器
這兩片應該是客訂的荷蘭Hypex D類晶體放大的模組,左、右聲道各一組
真空管放大部份,採用兩隻ECC802 S,與12AU7可替換
具有RCA與XLR輸入各一組
