Re: Follow-up on headroom

Frankly, it sounds to me an urban legend.
Maybe it can (could likelier) be true of one specially bad designed mike which gave birth to the motto?
All mikes with phantom power are to be built to work from 11 to 52 volts as specified, which includes the SPL at a given distorsion. Or it's just poorly designed. Which I don't believe from all manufacturers who want to stay on the market...

Maybe some will disagree, in this case, I would be curious to have them ask and read the manufacturer's explanation on this one (they would be admitting their mikes does not work as specified!)

BTW, this large span of voltages is typical of a standard built after many manufacturers had their proprietary solution having worked on field for some time. So, the standard is build in order to accept all the oddities and choices everybody did.
A standard built from scratch would specify for example 22V minimum, 28 volts maximum, drop-outs shorter than 10 ms...

In the same vein of late standard, ISO7816 (smart cards) is a marvel: each reader shall accept data with parity, without, inverse or direct, msb first or lsb first, intervall between bytes in 4 versions, etc etc... Such diversity brings nothing, but it's the way things are...
