Seventh Circle Audio

Hi, I've recently done a recording of a drum kit using A T15, two N72's and two A12's which I had only finished two days before. I had only done a voice check with the A12's but all seemed fine.
I set up the kit in a hall upstairs in the factory I'm based and used N72's on kick and snare, A12's on overheads wit ribbon mics and T15 for room mic... In doing this I made one fatal mistake .. I used a fifty metre multi-core. Now, one thing I noticed is that, apart from my overheads being week, and muffled to shit, the N72's seemed to work perfectly but A12's not. I initially put this down to them being ribbon mics but I did swap them round and the A12's sounded shite on kick and snare. I realise I have to do this recording again but, does anyone know why they would be different over long distance?
Anothe question I have is, if I put the pre's at the kit end of multi-core, will I get away with it? Bearing in mind that I will have to use and extra 3 metre loom from pre's into multi-core. Or, will I have ad the extra stuff on the pre's for driving signals over 50 metres?

Any help greatly appreciated

I'd double check the recently completed A12's since they seem to have an issue. Running a mic through a snake shouldn't have anywhere near that effect on them. The fact that you swapped the A12 and N72 and the problem followed the A12 is one hint. The snake itself could have been bad, too (those particular channels - but it would seem that you swapped cables for Kick/Snare eliminating that variable as well)

I was also thinking you might have fried the Overhead Ribbons with Phantom by accident? But again the fact that you swapped the questionable A12's to the Kick/Snare and still sounded bad pretty much isolates the A12 as the culprit IMO...

Having the Preamp close to the mics is preferred, but make sure the gains are set correctly! Most any Preamp is capable of driving longer cables than a mic is capable of itself (at least with fewer losses). I know Tim recommends the optional Inductors (in-place of the shorting jumpers) if you regularly drive really long cables.
