Check out this little mic baffle/recorder package I whipped up. It’s a special application not really designed for concert recording, but hopefully someone else can make use of something like this. Credit: this stuff is heavily inspired by Moke's Jecklin disc threads, with a little SparkE™ fishpole twist and a dash of bitters, served over the rocks of the Schoeps KFM 6/360 mic designed by Gunther Theile. Big thanks to everyone. [edit: lots of photos here, the photos of the final contaption are down in post #940001, the 11th post in this thread]
A little backgound..
I’ve been waiting for a decent flash recorder to come along and needed something last month to record classes, performances & jam circles at a great acoustic music gathering in NC that brings in some heavy hitters from the acoustic guitar, resonator, and mandolin world as instructors. Taping classes is encouraged and the R-09 became available just in time for the trip. I'd been planning on putting together a small decent quality recording rig and a week or so after it arrived I ordered a matched set of 4060's, MMA6000 and a few other pieces from DPA. Before I got a hold of the mini DPA's figured I could make a little Jeklin-disc like baffle to improve the imaging of the built-in mics on the R-09; something simple I could use while grabbing the class sessions. The R-09 mics seemed to have about the same spacing as the mics on the mini Jecklin-discs people have been building here.
Small ball baffle for internal mics-
The first thing I tried was cutting up a floating practice golf-ball made from dense Nerf-like yellow foam. I cut a notch in the ball to fit over the top of the recorder so that the mic capsules were on opposite sides of the ball. Pretty small baffle, but I figured I'd get a little more directionality on the high frequencies like those add on pressure modification spheres DPA makes for their omnis, hopefully rolling off smoothly as the source moved from one side to the other around the ball. A poor man's back to back 180 deg. close spaced Neumann M-50 wannabe config. I did a better job notching a just slightly larger diameter Nerf gun ball ($5 for a pack of 5 dense green foam balls) that I sanded to smooth the cut edges and flatten the opposite sides to still fit flush to the mic capsule vents. The ball just slips on the recorder, snug enough to stay put. It made a quite appreciable improvement to the smoothness of the high end, but didn't add much additional separation to the playback image.
