Loa cột gắn tường QSC AD-S402T
Dòng AcousticDesign™ AD-S402T là loa gắn trên bề mặt cột 4 trình điều khiển. Hệ thống toàn dải cao cấp này có khả năng tải bypass 70 V / 100 V hoặc 16 ohm, khiến nó trở nên lý tưởng cho nhiều ứng dụng nền trước và nền sau với môi trường khó khăn về âm thanh. Được trang bị hệ thống lắp ngang/nghiêng độc đáo, loa gắn trên bề mặt dạng cột cung cấp nhiều vị trí định vị cho phép loa luôn ở sát tường trong khi vẫn có thể nghiêng xuống tới -20°.

8 Reference plane is the plane coincident with the loudspeaker baffle plane. Reference axis is the axis perpendicular to the reference plane and passing through the center of the baffle. Vertical plane is the plane intersecting the reference plane at a right angle, including the reference axis and the taps selector knob. Horizontal plane is the plane intersecting the reference plane and the vertical plane at a right angle, including the reference axis.
