    Ah, yes, I see what you're saying. I usually just use one half of a balanced line and gain it appropriately if I'm using an unbalanced input without a balun, rather than shorting one side to ground, as I don't like shorting a side to ground (unless there's a ground loop issue to be concerned with, etc.). (In permanent installations, I use a balun and a slight gain to compensate for loss)

    yeah, I always tell my students to keep a balun in their vehicle. it always solves the problem.

    khv, yes, a 3-circuit plug and a TRS plug are the same thing. What you have described should work, if you've got mono out of the mixer. You have, yes?

    Aww, you shouldn't be so nice. You should teach them to carry transformer wire and a variety of cores, as well as how to wind them

    If I were going to be that much of a dick, I'd insist that they carry mu-metal too, and forms to bend it into shields, and gear to reprocess the stuff so it would get back its magnetic properties after bending.

    Oooohhhh.... mu-metal loses it's magnetic properties after being bent? I never knew that - I just cut to the size I wanted. More tidbits to remember for another project - thanks!

    Relationships are based on compromises - behavior accepted is behavior repeated.

    Even dropping a magnetically shielded transformer on a concrete floor can reduce a mumetal shield's effectiveness by 20dB or more. Not that it's useless, it's still orders of magnitude better than steel, but it ain't right.

    Mumetal is a mostly-nickel alloy that's formed first and then annealed in a hydrogen atmosphere. Don't try this at home, kids.
