Title: AD20 > MT = 24 bit
Post by: Steelcorner27 on November 18, 2005, 09:12:21 PM
Well I was just playing around with my Microtrack trying various things then I hooked my Denecke AD20 up to it via spdif and to my surprise it recognized the signal as 24 bit, now I know this pre puts out a 20 bit word,could this thing actually be recording at 24 bit? I haven't tried it in the field yet but in my at home testing the files verify out at 24 bits when analyzed in Wave lab. anyone else test this combo? anyone else have ideas on this?

Thanks
Brad

20 bits of data (output by the AD20) fit inside 24 bits. The lower 4 will be 0 when coming from the AD20.

So I could run: mics > psp2 > ad20 > MT @ 24/96 and it would sound better than a 16 bit recording?

except for a couple of things.  the AD-20 adds a minimum of 17dB of gain.  unless you run attenuators between the psp2 and the ad-20, I wouldn't want to run a pre-amp in front of it.  not too mention, I don't think the A/D converter in the ad-20 would be that much better than the converters in the microtrack.  you might as well run line-in from the psp2.  or just buy a mytek or a ad2k and be done with it :)

AD20 is fixed at 44.1 KHZ also

I think there is a 48khz version out there as well...but no 96
