The Behringer PX2000 Patchbay features 48 total points using balanced 1/4" TRS Phone connectors on both front and rear. The PX2000 is configurable for Parallel, Half-normalled, Normalled and Open modes. The Patchbay occupies a single unit 19 inch rack space. 充當無敵翻譯機一下 這東西是個patchbay，就是跳線盤，共48孔,分上下兩排,是使用1/4吋平衡式Phone頭來跳線的,可有parallel, half-normal, normal, open四種跳線模式[至於這四種模式是什麼,解釋起來有點長...] 我想背後應是用夾線的那種方式連接訊號線的, 不是傳統焊接式的.
