AU9 transforms ambiance-noise to an A-major triad.

A resonance-chamber receives sound waves and passes them on to 3 tuned strings. An electro-magnetic pickup converted the string-vibrations into electric signals. The signals are amplified and passed on to a line-out, where headphones and recording-devices can be plugged in.

AU9 was specially designed for the URBAN AUDIO AmericanSoundsTour. It is dismountable and can be stored in a case. The case can be taken on a flight as an additional piece of luggage.
