Xenosonic Audio Modulation DRSSTC Tesla Coil

The Xenosonic Audio modulator interface is featured here on an initial testing run hooked up to an Eastern Voltage Research miniBrute DRSSTC system. Not show, the Xenosonic is connected to a Yamaha S03 Synthesizer.

The Xenosonic is a universal musical interface for DRSSTC, SSTC, and VTTC Tesla coils provided PRF based modulation on monophonic inputs. One can connect a keyboard, guitar, acoustic instruments such as trumpets, saxophones, and even esoteric instruments such as Theremins with the Xenosonic interface.

I ordered the xenosonic board....Not such great audio quality even when I had a sinusoidal audio input. Blew my coil again and again :P

Firstly, the xenosonic board doesn't product great audio quality by any stretch of the imagination. It merely PRF modulates a high voltage arc by turning it on and off repetively at the audio tone desired. At best, this sounds like a buzzing on steroids - hardly anything of quality audio.

Secondly, if you were blowing your coil again and again, you obviously did not have the xenosonic set up properly for your coil (prf, pulsewidth, etc... not properly set)

And the keywords "even when i had a sinusoidal audio input" is a MAJOR clue. This means you obviously input other types of complex waveforms and did not follow the instructions. Remember, this is a simple zero cross detection circuit and complex waveforms with lots of harmonics will not work properly. You obviously did not follow the instructions.

nice thing... .but it sounds a bit like it's farting! :)

Oh well I meant when I inputted a clean sinusoidal audio signal it came out sounding sort of fuzzy and the coil didnt make really clean tones. I turned the pulsewidth up which seems like the only way to increase audio quality (obviously not analog good but good enough to get good tones) and get sufficient sized arc but the price of that is unreliability and duty cycle increase which causes everything to blow. Also I made the mistake of buying the board before the site was redesigned...

What would you amplifie??? i don't understand quite... the arc. or what???
