He still responds to Private Messeges info@pmi.com

knowdoubt said:Just one thing that kinda has me scratching my head about the color dot thing is - If true that they just classify a specific range of sensitivity & there is no more than a 0.05db difference between any mics within a given color class (which is very close tolerance), it stands to reason there would be no more than 0.15db variance between any mics across all color classes & would seem to me to be close enough to negate the need to group them into ranges for closer matching at all.
Dolemite said:
Yeah, 0.15 dB seems negligible, but that assumes that the three tolerance ranges are contiguous. That's another reason I'm thinking the different colors might represent different electronics. Then you might well end up with mics that have a few dB's of difference with different [internal] preamp implementations, but very close when comparing mics with the same implementation.

There may be a very few people who for reasons of their own, feel that this BBS is better of without Alan, unfortunately they also raised the ire of Harvey over their behaviour. From what Harvey said, I don't know that we will see him he much from now on.

knowdoubt said:According to that it's related to capsule tolerances. If so, the 3 tolerance ranges would pretty much have to be contigeous, otherwise a lot of good capsules (& $$$) would go to waste that fell in between the ranges. I understand what you're saying though. Another possibility is that Alan made a mistake or typo when he quoted me a tolorance value of 0.05db within a color range & perhaps it should have been more like 0.5db or 0.15db or something like that.
LooneyTunez said:I emailed Alan about the color codes this past week as well. According to the reply he gave me, there can be as much as a 4db difference in sensitivity between capsules, thus the reason for the different color codes. He did give me an example as to what colors were what sensitivity, but I'm not sure that it's actual data...seemed more like just an example to show how the sensitivity between capsules were different.
Well, Neumann guarantees their mics to be within +/- 2dB of their published curves. That means that one mic may be + 2dB above the curve, while a second mic may be - 2dB below from the curve, giving you a possible variation between any two mics of.....Dolemite said:OK, I stand corrected, it must be the capsules. I didn't realize there could be that much variance in sensitivity in the capsule itself. Having 4 dB difference sure says "crap QC" at the capsule plant to me...but at least Alan & co. are taking the time to measure output level (at a certain frequency), separating capsules and coding mics, because I'm sure there are other manufacturers who aren't doing this at all.
