Before I knew that there was any risk of blowing the audio on a Jamma board I would run standard Jamma boards on a Neo stereo wired supergun all the time, and I have never seemed to have hurt any of the Jamma boards in the past.

Exactly just how bad is it to run Jamma on a MVS set-up?

What happens when a Jamma board is pumping out speaker neg through the speaker left pos? and how does that effect the board?

I just bought a shiny new Jamma pcb and I do not want to fry it.

please keep in mind, my supergun is using a car line out adapter to convert sound to RCA if this makes any difference.

Thanks

OK, so Jamma Board in an MVS cab:
-Depends on the board. Some boards ALSO use a ground as a negative terminal, so in those specific cases you don't have anything to worry about.

If you are attenuating the signals:
-I'd say that the risk is minimal to non existent. In fact, many boards put out pseudo-stereo when hooked up in that rig. Some even get picked up by Dolby Pro-Logic and have strange 3D effects.

Or, you can just take the R-out off the supergun and split it.
