(a) The Audio Control Panel is contained in a box. The front panel of the Audio Control Panel is attached to the console with four captive fasteners. The Audio
Control Panel is made of alodine-treated light-alloy. It has the sub-assemblies that follow: - Cover subassembly
- Chassis subassembly - Front panel subassembly.
(b) Two fasteners secure the cover subassembly to the front panel/chassis subassembly. The rear face of the
cover holds the identification plate. There is an opening in the cover subassembly for the main board ARINC connector J1.
(c) The U-shaped chassis has two rectangular side plates. One of these side plates has the same identification plate as the cover. Two circuit boards to the chassis.
