Posted: Sun Jul 17, 2011 5:59 pm Post subject: Kronos and S/P DIF |
|
|
The Kronos has a "litepipe" type connector for S/P DIF and my Motu 828 mk2 has an "RCA" type connector for S/P DIF???
Is there an adapter available for this situation? Is there a way around it?
I tried to just plug the optical cable from the Kronos into the ADAT section on the MK2 but I only got one channel and there was a fair amount of crackling and upleasantness. Yes I have the Motu set to 48K
any ideas?
This is just the first in what is sure to be a long line of questions about the Kronos so get ready...
Thanks!!! |

On my mk3 it's possible to change the input type on the adat to optical s/pdif. This changes the cuemix at least to stereo for that input.
Have a look in the submenues of your interface or check out the Motu Audio SetUp application.
The reason for crackling when you don't do this is because of the time-slots in the multiplexing algorithm dose not align... the Motu is expecting 8 channels, not only 2... |

For optical/coax conversion:

Or, as previously mentioned you need to open the options panel for the motu device and tell it to configure that ADAT port as SPDIF.
Either way, make sure to tell the Kronos that the audio clock source is spdif instead of internal. This is somewhere in Global|Audio? |

Hosa also makes one.

I think you should check the Set Mode in your 828.. because your ADAT is configurable to Optical S/PDID.
Which means you don't need any converter. This is a quote from Sound On Sound:
The 828 MkII's LCD can be switched between Setup and Mix modes by pressing the Setup knob, and in Setup mode you can choose whether the optical I/O is ADAT or S/PDIF, you can choose the digital sync mode, set the headphone assignment and so on. _________________ Lou

On MkIII this is certainly like Lou says. I use MkIII in this way with M3. Consult your Motu manual or ask them directly about MkII - they used to be helpful. Also I have my MkIII as a clock master and M3 is set in Global mode > system pref tab > system clock as S/P DIF - so it is slave (I have both cables in/out connected) I found that it works more stable (though unfortunately it is not possible to record motu main mix back into M3 this way - you get unavoidable feedback loop as there is no way to disable input monitoring to L/R outs when sampling on M3). Perhaps something similar applies to Kronos as well. If you have Kronos as only digital input connected to motu, you can try to clock slave motu to Kronos. In this case Kronos will be digital audio clock master and motu will be slave. Also note - audio clock master/slave thing has nothing to do with midi clock master/slave |
