On the Death Star they used a video mixing console to operate its planet-destroying weapon, so I don't see any problem using some DAT machines to talk to aliens.Well known production classic.
Jodie Foster communicating with aliens utilising her trusty Eventide Ultra Harmoniser, also at her disposal she had the Focusrite Red 3 dual VCA compressor at the top, I'm not familiar with the second device and then a pair of Alesis ADAT machines.
