有兩種可能的組態,通常稱為水平和垂直雙放大。
在進行雙擴大機連接時,在連接揚聲器電纜之前要先取下縮短耦合線。
如果不這樣做,將會使擴大機受到損壞。
垂直雙放大
這種組態,各揚聲器系統都使用相同的立體聲擴大機 各擴大機
的一個頻道驅動低頻段,而另一頻道如下圖所示驅動高頻段。
將一組電線和擴大機頻道連接於接線柱的底部裝置 (低音驅動器

兩條負極 (-)電線連接於負極 (-)擴大機端子。
水平雙放大

個擴大機的各頻道驅動各揚聲器系統的低頻段,而另一擴大機的
各頻道則驅動中頻到高頻段,如下圖所示。
此方法要求兩個擴大機有相同的增益。否則,在來自揚聲器的低
頻和中頻到高頻播放之間聽起來會有不平衡感。
