Sujet convertisseur ou horloge?

CMC6-> j'ai retrouvé la doc digi dont je parlait plus haut:
http://akmedia.digidesign.com/support/docs/192ClockJitter_30957.pdf

je sais que les 96io et le rosetta c'est pas tip top

MAIS la question est de savoir si je perds tout bénéfice en chaînant toutes mes synchro (en ADAT actuellement), plutôt qu'en ayant une vraie horloge maître. Si quelqu'un a une idée...

je pense que ca changera pas grand chose, si ce n'est au niveau des conversions faites par le lavry lui même.
Quand à la distribution du signal d'horloge, il me semble que c'est préférable de le faire via word clock, plutôt que par les liaisons audio numériques type spdif, adat, aes.... (à confirmer) et encors, si ca se trouve tes convertos font du reclockage, donc ca changera que dalle.

There’s a widespread notion that adding a high-quality master clock to a digital system will somehow magically improve its overall performance. While that might possibly have been the case in the very early days of semi-pro digital converters where, frankly, some of the internal digital clock designs were pretty ropey, it certainly isn’t the case today. As I’ve explained above — and will prove below — today’s converter designs generally work best on their own internal clocks, and most will deliver a slightly poorer performance when clocked externally. The very best devices will show no change in performance at all, because they have superb clock-extraction circuitry that can remove all traces of clock jitter and other external clocking artifacts, so they work just as well as when running on their internal clock.
(...)
The obvious conclusion is that in simple digital audio setups a master clock is usually unnecessary, although it remains critical that multiple digital devices are clocked sensibly. In more elaborate digital audio systems, a master clock can make the task of slaving multiple units much easier and neater, and allow the system to operate more reliably. In systems where digital audio is being used in synchronism with video, an appropriate master clock is absolutely essential. But in any of these cases, the use of a master clock will not improve the audio quality achieved by the converters in any technical sense — and the most expensive clocks fare no better in this regard than the least expensive. The only relevant criteria for purchase is whether the clock provides the facilities, inputs and outputs required, and is designed sufficiently well to conform with AES11 Grade 1 standard.
