GP DMIC 20 question
« on: March 16, 2017, 07:59:56 AM »
do any of our local wizards know if its possible to somehow mod the pre to bypass the dac or upgrade the dac to 24/48 ?

ran across some older 414 and 461 > DMIC recordings that smoke and was wondering about taking it out again. Yes i know i can run  hotter on 16/48 but was curious

No analogue preamp actually has enough dynamic range for more than 20bit anyway.

Using a 24bit bit bucket will preserve all 20 bits with this unit.
Recording:
Capsules: Schoeps mk41v (x2), mk4v (x2), mk22 (x2), mk3 (x2), mk21 & mk8
Cables: 2x nbob KCY, 1 pair nbob actives, Darktrain 2 and 4 channel KCY extensions:
Preamps:    Schoeps VMS 02iub, Naiant Littlebox, Naiant IPA, Sound Devices Mixpre6
Recorders: Sound Devices Mixpre6, Sony PCM m10

Home Playback: Mytek DSD 192> McIntosh MC162> Eminent Tech LFT-16; Musical Fidelity xCan v2> Hifiman HE-4XX / Beyerdynamic DT880

Office Playback: Grace m903> AKG k701 / Hifiman HE-400

I ran 481>DMIC20 from 1999->2003 when I got a V3 and I did pull some smokers with that combo! If the DIP Switches for gain weren't such a PITA it would be a great lil Pre/ADC Combo for a small 16bit rig! Ive seen people mod the dip switches with some gain knobs on the top of the unit! Always wanted to try that when I had mine back then, jus5t to avoid the dip switches lol ;D

And as far as I know, you CANNOT bypass the ADC stage, unless you mod the inside chips or something like that most likely!
