I hope it doesn't seem too strange since I often answer people's questions about Schoeps microphones here, but: There's a setup that they offer that I've never tried and am thinking of trying. Could I just ask whether anyone else here has tried it, and if so, what were the pros and cons?
People here seem to be pretty familiar with active cables, but in concert recording, active extension tubes are at least as widely used, particularly in Europe These are thin (~1/4" diameter), long, rigid, hollow Nextel-finish metal rods that have a fitting for a Colette capsule at one end, a fitting for a CMC microphone amplifier (body) at the other end, and a shielded cable inside. See the attached photo for one prominent example of their use. I use these sometimes in closely-spaced stereo pairs to record classical concerts.
Anyway, Schoeps also makes a tube for coincident stereo recording or for the "redundancy" (safety factor) of having two microphones in the same place. You can't adjust the angle between the capsules--there's an up/down pivot for angle adjustment of the two capsules as a pair, but they both face whichever way you turn the tube. If one of the capsules is a figure-8, you can make an M/S recording this way. And that would put even less "hardware" in sight between the audience and the stage and the performers than anything else I can think of.
So I might like to try it out. Has anyone else here done so already?
