It's a (surprising) option. Pg 33 of manual:"Line (+48V) Use when connecting equipment with line level input that requiresphantom power"
what would it take to overload the analog input in a real life situation?
The open question I'm still seeking an answer for is why 32bit fp was also tacked onto that, because the dynamic range capability of 24 bits also exceeds the dynamic range of the recorder's analog input stage and could have been used in exactly the same way.
In comparison to a traditional digital recorder, a multi-ADC design does not in itself increase the overload point of the recorder nor decrease its noise floor. Those thresholds are determined by the the analog input stage ahead of the ADC. What implementation of the dual ADC scheme does is increase the dynamic range of the ADC stage enough that it matches or slightly exceeds the dynamic range of the analog input stage, thereby avoiding the need to manually adjust input gain. It doesn't increase the dynamic range capability of the ADC by a massive amount and doesn't need to, it only needs to increase it enough to slightly exceed the limits of the analog input stage.The open question I'm still seeking an answer for is why 32bit fp was also tacked onto that, because the dynamic range capability of 24 bits also exceeds the dynamic range of the recorder's analog input stage and could have been used in exactly the same way. I think its based in marketing. Manufacturers get to talk about +700 dB of dynamic range, being impossible to clip, all that. But those are the aspects of the file format itself and not the recorder feeding it. It totally ignores the real world constrictions of the necessary signal chain ahead of writing ones and zeros into the file format.
A little birdie told me that the F3 preamp chip isn’t even likely to come anywhere near 24 bits of resolution ( or even 16 bits). And listening to several recordings, I can hear that. 32 bit is great but the actual resolution is set by the preamp, and 32 bit float does not change that.
maybe my question earlier was stated well...cuz i finallyfigured out what the +1-16 option next to the line inI saw a youtube video where a guy recorded at +16 and +1 and then showedthe signal no matter how quiet or how loud could be adjusted in postso the questiion i have for all of you iswhats a good setting for a feed from a baby box - line ini've been hearing put it at +2anyone got idea?Taz

You are not setting the recording level (gain), that is set by the recorder. You are just setting the post recording output volume, (fader). What you choose will not at all affect the sound quality even if the setting you choose is way too high or way too low. Your choice only affects what you do in post, and has nothing to do with the recorded sound level (gain). Your setting that would perhaps give you the least work in post (if that matters to you), would be best determined by the preamp and loudness of the show, just like any recording. The biggest difference is that if you choose a level too high or too low, it does not matter because it is not the recorded level (gain) it is the output level (fader)
