I always thought the Calf dithered to 16 bits in much the same way the AD-20 does. I hope that's the case.
No - assuming a 16 bit recorder - They truncate to 16 bits - no dither...assume the same occurs with the AD-20.
hmmmmm, I don't feel like going digging but wasn't there alot of talk in past threads over this. If memory serves me correct (often times it doesn't) the 20bit ad's are giving you the full 16 bits, with a more natural truncating since you are not using all the 20bits anyways (unless your pegging 0db constantly) so you are actually getting the full 16 bits using a 20bit adc. Maybe I'm way off target, but this is how it was explained to me.
Isn't the sbm-1 a 20 bit adc. Same with the ad1k, ad-20, flying calf, dmic-20......
