2021 - kinetic sound and video installation


The title of the work refers to the device designation of the used plasma screen. It is a common device that has been used for many years in exhibition and event contexts. However, this screen has become obsolete due to recent technological developments. With the installation TH-50PH10EK WALL, this object is transformed from a carrier of art into a work of art.

A 50-inch plasma screen is installed as a pendulum, which swings out freely on the wall after being triggered. As soon as the screen comes to a standstill, it is pulled back into the original position with the help of a cable winch and is made to swing again – triggered by pulling a ripcord, a performative act that cannot take place without human intervention and which involves the exhibition supervisor in the installation. Each cycle ends when the screen has come to a standstill and no sound and video is produced by its movement. The sound is generated by the amplification of the friction which the back of the screen is subjected to on the wall. The visualisation on the screen is a direct translation of the analogue audio signal into an analogue video signal. Voltage and frequency are represented by a speaker in sound on the one hand and as flickering horizontal white lines on the screen itself on the other hand. There is no processing of the signal, for example by a computer or an effects device.

In his works Tiefengraber plays with the meaning of the function of the devices and objects used. He breaks with their predetermined purposes and modifies them. This experimental approach and exploration of old and new technologies and their combination can also be found in the work presented here.
