Braun R1
Braun Atelier R1
1981
1985
Center of the "Atelier R" system, with the Atelier 2 and Atelier 3 taking on a more high-endish style and pricetag.
The stark and sober designs of Prof. Dieter Rams were getting here a little too crowded with functions and displays - sign'o'the times : form could not follow function anymore.
But perhaps more interesting than the R1 itself is what Braun was planning to unveil in the coming years :
CD1 CD player
DC1 Digital Cassette recorder
VR1 Video recorder
VR1 Video Disc player
HD1 Concert Hall Decoder
AV1 AV control center
VT1 Video tuner
VM1 video monitor.
Yes - almost all digital, all A/V and surround-sound oriented !
This would have made quite a set... if the japanese sledge-hammer industry didn't make it impossible for Braun to compete, and if Gillette, majority shareholder since 1967, didn't think more cash would be coming from electric razors than stylish (and excellent) high-fidelity.
All Atelier units were made of aluminium fronts and sides, with plastic for the top and steel for the bottom plate.
A flap at the back hides all cables, conveying the power cords through the AF1 stand as well.
Producing in ever smaller numbers the famed "Atelier" series, Braun withdrew from the audio market in 1991, after two years of colossal losses and lack of sales.
Most of these prospective units never saw the light of day.
