最近購入的兩台UREI LA-4,還沒有正式上線測試;不過有拿到TheWall小小的玩了一下。
在操作上有個最大的不同,threshold的設定方向和大部分的機器是相反的。
大部分其他的壓縮器的threshold操作方向是,往順時針方向,是「升高」threshold,逆時針則是「降低」。
而LA-4是,相反,順時針方向是「降低」,逆時針方向是「升高」。我想它的邏輯,是以threshold的觀點來設計的,順時針方向,降低了threshold,讓threshold作用「愈大」,如果逆時針轉到底,到了「0」的位置,代表無完全沒有作用,表示所有的訊號都低於threshold。

總之這是需要習慣的。

照一下內部照片。據說,LA-4需要改掉某個OP AMP聲音才會好聽。
