For audio input, a single VLA42 was installed thanks to easy operability, the option to plug-in up to four audio sources, and the use of an external wall panel (VRE11) offering easy control for staff and the ability to plug in a fifth local device via a 3.5mm TRS socket. The VLA42 was also specified with the optional JUP2 19” rack-mount kit allowing both the VLA42 and 4SDL160 to be fixed in to a flight case taking up only 3U of space.
