Sound Blender - Manipulating the (VGA) Monitor Signal

By Wolfgang Spahn

Nam June Paik is known for manipulating a TV set with a magnet. One might think that after we abandoned monitor tubes the combination of TV and magnetism is gone as well. But even today something similar is still possible by manipulating the monitor signal. The fact that VGA is a signal based on electric current makes hacking easy.

One can manipulate the signal with coils and magnetic fields. As VGA’s are similar to sound signals an easy transfer to sound and vice versa is possible. The “VGA & Sound Blender” is a small, analogue signal mixer for VGA signals, sound and all kind of other signals.

One can easily blend different signals and mix them with signals provided by analogue synthesizers. Thus the “VGA & Sound Blender” is a perfect board for live analogue light-sound-performances.


• hack the VGA signal of our computers.
• learn the basics about the VGA and how to manipulate, mix and sonificate the signals.    .
• build a “VGA & Sound Blender” and learn to use it with our sound- and video equipment.






about the workshop holder

Wolfgang Spahn is an Austrian-German visual artist based in Berlin. His work includes interactive installations, miniature-slide-paintings and performances of light & sound. His art explores the field of analogue and digital media and focusses on both their contradiction and their correlation. That's why he is also specialized in re-appropriated and re-purposed electronic technologies.

Spahn teaches at the Professional Association of Visual Artists in Berlin (BBK-Berlin) and is associated lecturer at the University of Paderborn, department of media studies as well as at the University of Oldenburg, department of art and visual culture.
