Led Zep interview snippet
Rick: And you've finished your new album?
Plant: We finished that, and we did it in our own home. Well, how it went was that we used a mobile truck for our recording unit and we went to an old manor in Surrey. There we put up all the equipment in one room and stuck all the mike leads through a window. Straight into the recording van. So anything that we did just went straight down on tape. Bit by bit it grew up into a great collage of numbers.
Rick: Do you like it?
Plant: (nodding head): Yeah. It was another atmosphere altogether.

The mobile truck he's referring to had a Helios console in it.
Looking around the web quickly - I cant seem to find any supporting evidence regarding the M160's as the mic's actually used.. So I will have to re-enforce that my opinion was a hunch more than a presented fact and a matter on which I still seek clarity!
Here is the original statement -"I believe the M160 + Helios is the Zeppelin overhead drum signal chain (ain't it?)"
Along with did AW use use samples on the mix of Nevermind? - this could be perhaps one of the great unanswered audio engineer mysteries of our time!
