Thread Starter | Digidesigns Digital I/O box Does anyone use Digidesigns Digital 192 I/O in their rigs with other AD or DA converters? I'm talking about the 16ch box with AES not the regular 192AD. Just wondering if it did anything to the sound? My thinking is with this box you could have for example an 8ch Mytek AD and 2ch AD's from Cranesong, Lavry, Benchmark etc giving you a lot of different flavors going into ProTools. I figure if you can have various flavors of mics and preamps why not AD's too. Of course this would work optimally if Digi's Digital I/O didn't screw with the sound any. Thoughts...? -John |

| I´m using a Cranesong Spider as an alternative AD converter on my 192´s AES Inputs and it works just fine. I like the cranesong over the 192´s AD´s especially for drums.  Will try the apogee rosetta 800 in the near future. |

it does nothing to your sound. it passes whatever you feed it in or out of it. It offers to handle your digital signal in a very versatile way though. Routing / format assignments / different sample rates etc ... and of course integration in you Protools setup. It's basic idea is to get digital signals in and out of Protools through external peripherals ... wether those are FX or AD or DA ... doesn't realy matter ... Lots of people welcomed the all digital interface exactly for the reasons you described.

| Yeah 192 Digital I/O: an INexpensive (probably only in Digi terms) Protools dongle!! Well it does more than just passing the digital signal to and from PT HD. Real time conversion (if any good?) should help a bunch when you move up to 96K and want to use those boxes like Kurzweil KSP8 via digital I/Os. Lately I've been surprised on how much you loose by sample rate conversion.. from lets say 48k down to 44.1k... amazing... do the mix and try A/B-ing original @48k and srconv.@44.1... huh...!! Anyone noticed that??? I wonder what happens when you SRC from 96k to 44.1k?... Some serious Pitagorian math calculations going on there... some say they prefere to work @88.2k rather than 96k 'cause the math algorhythm is more simple, more like halving when SRC (88.2 to 44.1) and they say it sounds much better. Anybody?? Also I'd use an external Word Clock to 192 rather than syncing it through the AES/EBU!! The sexiest looking dongle for the money! (I love its sound as well, much better than the standard 192 I/O IMVHO)  !! Greets...

| I'm using the Digi 192 Digital i/o with a KSP-8 via ADAT connections... works perfectly. The KSP-8 is being used for both fx and a/d d/a.

... and are you using it @96k (or 88.2k) Sample rate converted? Have you tried that at all? I'd be very intrested in hearing your findings... All the best | |

Thread Starter | Thanks!! Awesome stuff guys.  This is the info I wanted to hear. The Dig192 might be a little expensive but there are many ways it will come in handy.At least this way I can experiment with different AD/DA's to look for conversion possibilties other than those offered by Digidesign. I'd like to give the 8ch Mytek a shot. The word on the street is that it's fairly transparent and goes up to 96k (if you need that). -John |

| Here's the Digi's info on the specs of 192 Digital I/O: Features * Supports up to 16 simultaneous channels of AES/EBU I/O at 96 kHz * Supports up to 8 simultaneous channels of AES/EBU I/O at 192 kHz * Extremely flexible digital I/O: 16 channels of AES/EBU, TDIF, ADAT I/O; 2 additional channels of AES/EBU or S/PDIF digital I/O; 8 additional channels of ADAT optical or 2 channels of optical S/PDIF I/O * Switchable, real-time sample rate conversion on digital inputs , which allows easy streaming of digital signals at any sample rate * Word (1x) and Slave Clock (256x) input/output * Expansion Port that allows for direct connection of another 192 Digital I/O, 192 I/O or 96 I/O * Legacy Peripheral Port that allows for connection of 888|24, 882|20, 1622, or 24-Bit ADAT Bridge I/Os* * At 48 kHz or lower sample rate One would presume that ADAT I/O on the digital I/O would do realtime SRC... 48k in to 96k (or 192k) session! It's a upsampling process! Would the limitation of the Adat protocol (48k max) matter in this case?? Anyone??? |

All I know is that when selecting the ADAT i/o in ProTools, the "enable SRC" option for those ports becomes inactive. Another thing: the "base" digital i/o's DO NOT have the option for SRC... only the add-on slots (the sixteen banks of TDIF, AES, etc.) | |

| ManicHouse Thanks alot for your info... This really sucks for me... now I need the AES/EBU card for KSP 8 or an extra Analog I/O so to run tha thang at 96k... hmm, just bought the ADAT I/O few months ago... Cheers bro! |
