Rogue Audio Metis Magnum
前級內部公開
這台Metis前級也是Magnum的版本,包括更大的電源供應與模組,更大的耦合電容, Cardas配線、更好的電容、電阻、鍍金真空管座...等等
- Larger power supply
- Power supply mods
- Larger coupling capacitors
- Cardas output wiring
- Polypropylene byass capacitors
- Precision Dale-Vishay resistors in critical spots
- HexFred diodes
- Gold tube sockets
- Magnum logo on faceplate
若是有對照原廠官網非Magnum版本的內部圖,就會發現Magnum好很多
使用兩隻6SN7真空管,原廠外盒有標示那隻要插在前面
還有真空管的保護金屬罩,蠻實用的
前級的遙控器,用來控制音量
Metis有12dB的增益放大,內建的MM唱放為38dB,前方有動差式的耳擴輸出
介面方面,有4組RCA輸入(line 1,2,3與MM唱放),1組固定的輸出(不受音量控制)、1組受音量控制的輸出
完全在美國設計與生產

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
充足的電容群
具有RCA與XLR輸入各一組
General Features:
- Large high performance torodal transformers
- Massive linear power supplies
- Balanced (XLR) and single ended (RCA) inputs
- Heavy-duty gold plated binding posts
- Two 12AU7 tube complement
- Short circuit protection
- Standby circuitry for solid state components
- Slow start circuit for extended tube life
- Machined aluminum faceplate
- Heavy (2 ounce) copper circuit board
- All precision components
- Fully tested, burned in, and auditioned
Specifications:
- Output power Medusa: 200/400 WPC 8/4 Ohms
- Input impedance: 200K Ohms
- frequency response: 10Hz - 20KHz ± 1dB
- THD: <0.1% typ., <1.0% at rated power
- input sensitivity: 1.0V RMS
- dimensions: 18" W x 15" D x 5.5" H
- weight: Medusa 38 lbs
- power requirements: 115/230V - 50/60Hz
