I have a sort of odd situation here.
I want to set up a preexisting audio snake for an installed mixing console so that I can feed some in-ceiling monitor speakers from an aux on the board. So basically I would have, say, send "C" on the snake, which leads via the ELCO connector to the main rack, and from the main rack that send would be connected to the "long" line that goes to the in-ceiling speakers, >100' away.
The problem is, the mixer only has unbalanced auxes for some dumb reason, and the speaker amp will be at the other end of the "long" line, and also only has unbalanced inputs. I know I need a balanced line along the long run to keep out interference, but I'm not sure how I should do it. I was thinking of installing a direct box or something in the main rack, so basically the unbalanced signal coming from the multipin breakout in the rack would be connected to the direct box, which would be connected to the long cable run, but even then, should I just leave the shield unconnected at the other end? I'm not too worried about the unbalanced out of the mixer, not much I can do about that anyway, and the hum pickup along that run isn't so bad (tolerable at least for this application).
Anyway, how would you go about this?
Thanks,
Dan
