OK, I'm gonna be building a general purpose Supergun, which means that I can't rely on the MVS's wonderful headphone sound output anymore to give me a nice 5V sound wave that I can feed into my TV/Stereo and not blow them up in the process.
Here's my question: Those of you who have Superguns and use the standard JAMMA sound output, do you step down the voltage or just adjust the volume slider all the way down to get it at an acceptable level? See that solution might work for an MVS, but I don't think the Hyper has a volume adjustment, and I definitely want a Hyper board. So here is what I THINK may be a decent solution:
Build a small circuit using two Inverting Amplifiers. I have to use Inverting Amplifiers since they will allow me to have a gain less than one (aka Attenuation). The first amplifier will basically have gain set to 5/12 so as to give me a 5V driven sound wave. Problem is it'll be 180 out of phase, so I'll put in another inverting amplifier with a gain of 1 to get the signal back into its original phase (pretty sure this is necessary, I may be wrong but it can't hurt to put it in there).
Anyway, I'd gladly take some help from people who have a Hyper or equivalent board hooked up w/ the JAMMA sound being fed into their TV. How do you guys have it set up?
