living sounds said:"Discrete" as in resistor ladders (or other single components) - or do you mean 4 AD ICs per channel?
I'm not sure but I know there were no AD IC's that gave anywhere near that performance in the early 90's.

iampoor1 said:I wonder if they rolled a custom A/D converter using an FPGA? That might be what's under the heatsink....Might explain the "discrete" aspect too IE: They designed it out of discrete gates in the FPGA ;D
mhelin said:Currently AKM's AK5578EN (8 ch A/D) for an example can be configured to parallel it's all eight converters for 130 dB SNR (112 dB THD). You will still need two chips for 2-channel conversion to get that SNR.

Yup... 3dB for every doubling so 1-2 is 3dB, 2-4 is 6db, 4-8 is 9dB... not nothing but they would need to go to 16 for the next 3 dB.mhelin said:Currently AKM's AK5578EN (8 ch A/D) for an example can be configured to parallel it's all eight converters for 130 dB SNR (112 dB THD).

Patents are published so you should be able to read what they claim...cyrano said:Zoom has a seemingly similar 32-bit setup in one of their new portable recorders. The Sound Devices one is patented. Wonder what's original enough to get a patent for it. And who they'll hit with it, of course.
By law the patent is supposed to show the "preferred embodiment" or best way. While I have never heard of this happening, obvious obfuscation could be used to deny an application from ever winning a patent.cyrano said:This kind of patent is usually heavily obfuscated, if it is already publicly available at all...
