Made of sturdy sheet metal, the Rear Protection Plate not only protects the electronics of the LINEAR 7 118 Sub A / LINEAR 9 118 Sub A from splashes of water, but also from unauthorized access in cardioid mode. Thanks to the keyholes, the wing screws only need to be loosened slightly to remove the plate. The grille required for ventilating the electronics is backed with acoustic foam, effectively protecting connections and controls. The acoustic foam also serves to dim the LEDs, which is helpful in cardioid mode on dark stages, while still allowing the LED status to be seen.
