There are seven strands of electroluminescent Wire (EL wire) which are six feet long and connected to the output of a power amplifier by means of a 50-to-1 step-up transformer and a six-way crossover. The amp is driven by a music source and its output, via the transformer, lights the EL wire in proportion to both the amplitude (voltage) and frequency (as determined by the crossover links). Gain on the power amp is pretty nearly all the way up and voltage to the EL wire is between 0 (no light) and roughly 80 volts AC (music waves). This view is looking down at the EL wire. The crossover connects the following wires to the following frequencies: Green - 20-800Hz; Orange - 20-1600Hz; Red - 800-5000Hz; Yellow & Pink - 1600-7000Hz; Purple - 5000-20000Hz; Blue - 7000-20000Hz. There are persistence-of-vision effects which occur watching this art work in person. Direct link to movie file is http://homepage.mac.com/credmond/concepts/Proof_of_Concept_3.mov.
