In Reply to: Re: Are the sonic benefits of clock-syncing signficant? posted by Max on March 26, 2002 at 02:30:15:
How does that increase jitter? Or put another way, why would any of the ADC's come with clock-sync capability? I guess you're saying that it's best to make the ADC's internal clock the master, and make everything else slave to *that* clock...?Mike

How does that increase jitter?Well, you're sending the clock over a cable. It may not hurt a lot, but it certainly doesn't help.
Or put another way, why would any of the ADC's come with clock-sync capability?
One possible reason is if you need to use more than one ADC box at the same time and want to keep all channels in perfect sync. There are probably other uses.

Definitely.
I respectfully disagree with some of what youve said. Clock sync was originally added for the purpose of keeping a whole system on one clock (necessary for video, and some audio such as multiple ADC uses) however since clocks have become much better in recent years, outboard clocks can improve the AD and DACs of lots of gear. You are right that performance is degraded over that same clock built into a piece of gear since it is going over wire but since that clock isnt imbedded in a digital stream it isnt so bad and since lots of clocks are terrible, outboard clocks can make a positive improvement. Heck, George Massenberg uses a genex with his dB technologies AD and DAC's which are fabled to have amazing clocks.My findings on this are backed up by noting that my RME converters (which have pretty good clocks) dont benefit much (but some) from the ultra low jitter genex clock but my digidesign 888 boxes do benefit a lot.

Adding a little more into all your arguments. Wether or not you are using multiple DA's or AD's isn't the point. All the different digital equipement in your chains must clock to a common clock!! In a DA situation, it is likely to be clocking to the input source working as a slave. Digidesign 888's are not in my opinion good AD or DA devices anyhow. Run Pro-tools, a DA 88, and a 02R desk and see the problems you get if you try to have more than one Master clock in the system.regards
