THANKS SO MUCH for the additional pics dgirardin -- I stand by my guess that this device is some kind of "color organ" meant to control various banks (?) of colored lights of some sort, responding to an 'input signal' from an otherwise external sound/music amplification system. Probably not anything that'd be used around a 'radio station', much more likely for a dance hall/club or someplace...?? A *most interesting* item indeed, any way or the other!! <applause>
I’m really only guessing but my first reaction was it’s for sound not light. Each color refers to a set of cables those are volume controls.
Imagine this in the 1950s

With due respect DairyGodmother, the sort of 'color coded' connectors as seen in your pic are a much more recent 'invention/standard' meant for modern/current (mostly 'digital') sound/video equipment interconnections.
The connectors on the back of dgirardin's box here are mostly 120VAC plugs, (output probably, except for the 2-prong one on the upper LH side, not sure what that'd be for except it is probably also a 'line voltage' connector for something?) plus a pair of "RCA" style and a "DNC" style audio signal connectors (input, presumably) that'd take an audio signal from an external source, then do something to react to it in real time and in turn control something else to react accordingly. (light banks) Typically such devices kinda randomly divide up the 'frequency range' of music into a few (4 in this case) "channels", such that the bass frequencies activate one channel (color), the treble frequencies activate another, and so forth.
I'd still have to guess it was meant to control a small 'light show' in coordination with amplified music, whether a small stage/live band or small(ish?) club/dance floor environment.
DEFINITELY an interesting and unique item/puzzle, anyways about it -- THANKS SO MUCH for showing it, dgirardin!! :-) :-) :-)
