Equipment cabinet Braun Atelier HiFi GS4:
Quote from the Braun brochure from back then
"The equipment cabinets GS4, GS5 and GS6 were designed as base cabinets for all Atelier audio and video modules: they are just as wide and deep as an Atelier module. Thanks to the same dimensions, the equipment cabinets can be placed next to or on top of each other in any combination. So you can set up your Atelier system with the Atelier cabinets however you like. Even freely in the room: The equipment cabinets also function as room dividers, because they are painted on their own sides. And the Atelier system can stand freely in the room, because the cables on the rear sides are covered by panels. The cables are routed in our equipment cabinets - behind a cover strip on the back."
