Nice test setup, but as the rest of the posting notes, as well as most of contents of this tread say, 24/192 is pointless. While the Neuman U87 is a great mic, and used in studios all over the world, if you get the specs from Neuman, see http://www.neumann.com/?lang=en&id=current_microphones&cid=u87_description It has a claimed Frequency range 20 Hz ... 20 kHz but if you look at Neuman's own test plot: http://www.neumann.com/zoom.php?zoomimg=./assets/diagrams/u87ai_diagrams.htm&zoomlabel=Diagram&w=878&h=278 you see that its down 5 dB at 20kHz and the curve is falling off rapidly. Eyeball looks like more than 6dB per octave. There ain't gonna be any signal over 30kHz. And the Struder has its own fall off well over 6dB per octave over 20kHz. So its gonna ignore any signal that the Neuman sends its way. The choice of a 1/2 inch 2-track is smart, their decks with more tracks have worse rolloff. The usual tracking 2" x 24 track Studers can't do as well as the 1/2" 2-track. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
