A "natural" sound, neither "live" nor "dead"
The studios were designed by Los Angeles-based Peter Grueneisen. Pursuing a "natural" sound with properties in between a "live" and "dead" sound, Grueneisen brought all of the materials with him from the United States before construction began, including flooring and wall materials, concrete diffuser blocks, wooden diffuser boxes, air-conditioning ducts, and even wallpaper.
Each booth in the studio naturally features a glass window in front, but there are also red-bordered windows in the top portions of the walls that separate the booths so that the artists do not feel so "cooped up." The ceilings of the booths are 4 to 6 meters high. The booths are wide enough to accommodate a drum set, particularly the booths in Studios 1 and 2, where even a full-sized Steinway grand piano can be accommodated. Booth construction also reflects a no-compromise approach.
The power comes from clean power sources and runs through custom-built wiring that uses oxygen-free copper. Separate 117V and 230V power supply systems are provided for imported equipment. And the mixing consoles have been customized at every turn, for example by replacing standard contacts with gold contacts, to reflect the obsession with sound quality. With respect to equipment, the inventory of microphones alone features about 300 mics of about 80 different types. If you dream about a recording session that uses only vintage (vacuum) tube mics, it can happen here.
