Connectors IN LINK 2 × 2-point screw terminal X4i is provided with a connector sealing plate with two cable glands for 2.5 mm cables. If only one connector is used, replace one cable gland with the protective plug. Pass the cables through the cable glands before connecting them to the screw terminals.
Rigging system description X4i features one M5 insert and screw on each side to secure X-U4i or X-B4i. Three M6 inserts and screws at the back of X4i are available for compatible rigging accessories. Secondary safety for own enclosures Use one insert at the back of the enclosure to implement a secondary safety.

Rigging system description It can be used to mount one X4i on the wall or under the ceiling, with tilt adjustment. 70 mm / 2.8 in 2 x Ø 6.6 mm / 0.26 in Fasteners for wall-mounting or ceiling-mounting Secure the bracket with two M6 screws.
The U-bracket can be tted to a microphone stand with a Ø 10 mm threaded axis (European standard) and the matching locking ring. Adapter for US microphone stand Use a 3/8"-16 male to 5/8"-27 female microphone screw adapter and a locking ring to mount X4i on a US standard microphone stand. X-B4i X-B4i is bracket compatible with X4i.
