MIMESIS 37S NEXTGEN
PREAMPLIFIER
立體聲前置放大
Goldmund Mimesis 37S NextGen 是一款高端模擬立體聲前置放大器。 它使用多個並行前置放大器級降低噪聲和失真的能力簡直令人難以置信。 Mimesis 37S NextGen 採用完全雙單聲道結構，帶有處理器驅動的鏈接衰減器，使用單獨的電源單元實現最佳降噪效果，並使用 4 個單獨的電路進行 2 個連續的功率調節階段。
音頻電路質量
Mimesis 37S NextGen 提供 7 路輸入——5 路非平衡和 2 路平衡模擬輸入——和 3 路輸出——每通道 1 路非平衡磁帶環路和 1 路平衡和 1 路非平衡模擬輸出。 它還可以防止接地迴路和交流線路掉線或中斷將觸發和自動靜音。 Mimesis 37S NextGen 是模擬前置放大器的參考，並且在未來幾年將在音頻電路質量和聲音方面保持不相上下。
