I have my DA7 setup for WCK-In and my Lynx AES-16 card is sending wordclock to it. I was under the impression that whenever I opened a new song in Nuendo that the DA7 would follow the Lynx AES-16 lead and switch sample rates to suit the new song but it doesn't. I have to keep switching things over manually, is this the way it is supposed to operate?

I never needed wordclock cause i set the da7 to be the master.

But surely that means that if you are using a DAW program and record different projects at different sample rates then you have to still switch the 7 between 44.1 and 48 manually

If you are using the wordclock input BNC and have selected it, it should follow. On the D I/O page under "source select", you should see it change.
Make sure you are selected to the source you want to lock to.

Brilliant.

Nope it just doesn't work. If I switch projects in Nuendo going from a 48kHZ sample rate to a 44.1kHZ rate then my Lynx Studio AES-16 automatically switches too. I can check that in the Lynx software-based meter window. However, the DA7 still stubornly stays at the original rate until I go in and maunally change it over . If I forget to do this then it causes the expected clicks on playback which acts as a warning. The clock coming out of the AES-16 is OK and it's definitely going into the right port on the 7 which is terminated by using the small switch at the rear. Anyone??

Be sure that the DA7 isn't running under automation.

It won't allow you to change Fs in a session.

Maric,

I had high hopes that this would cure the problem, but when i checked automation was disabled. BTW, when i receievd the board fom the seller I did a complete factory preset reload, would this have activated something on that could be causing the problem? When I select WCK-IN instead of manually selecting either 44.1 or 48 I do get an "wordcock error message" in the bottom RH corner of the screen and it messes with my AES-16 settings too. Manually selecting the sample rate to suit the song file in Nuendo removes the error code and the songs playback normally.

What version of OS is in the mixer?
It should automatically detect the sample-rate (mine does).
A master re-set shouldn't effect anything.
In fact I'd back-up and re-set it again.
Good luck,

If you're using the DA7's BNC clock input and the computer is the master clock be sure that the DA7 termination switch is set to "on".


If you're clocking to an AES cable from your card to an AES card in the DA7 then "Wordclock in" is the wrong setting. You then have to set the DA7 to slave to the card slot that's receiving the clock.

OK, you might be on to something here. The AES-16 PCI card has 2 AES ports each giving me 8 I/O's. I had to have 2 custom digital cables made up by a very reputable company back east (Redco). The cables are Yamaha pinout at one end (Lynx) and Tascam/Panasonic (DA7) at the other and are 10' long. Since one format includes wordclock in it's pinout (Lynx AES-16) and the other dosn't, they provided a special breakout clock connection at the Lynx end. All I needed to do was to then run a standard BNC cable from this special breakout to the DA7 clock input.

Are you telling me that this is an incorrect proceedure? or is your comment only valid under certain conditions

It's a MK 2 with the final software version available.

Boy... not helpful perhaps and FWIW, but I have the MK1's with the entire studio driven by a WC amp via BNC. Switch the WC amp to either 44.1 or 48K, and both DA-7's follow suit, NP.

It ain't happening for me

Maric, where are you when I need you?

If the breakout cable is at the Lynx end wouldn't you be feeding the DA7's clock to itself? The BNC would have to be at the DA7 end.

If I"m misunderstanding you and you're sure that the cable is feeding your computer's clock to the BNC input of the DA7, then please check your termination switch.

Yes, this is what I am trying to do, I want the lynx AES-16 and the DA7 to follow my recording DAW program not the other way around. The Lynx already does this but the 7 won't so far. I definitely have the termination switch correctly set according to the DA7 user's manusl

The Lynx should be providing the master clock in this setup.

And you're quite sure that the BNC connector is a clock ouput from the Lynx and not an input?

Yes I'm definitely sure. On the AES-16 Port A is the clock input and port B is clock output according to the AES-16 manual and that's the way I have it connected. This is really weird.

I just spoke to Pual in Tech Support over at Lynx. He confirmed that i have the AES-16 setup correctly to output clock to the DA7. He also added that I didn't actually have to use clock to sync the two together since syncing also takes place via the AES cables automatically. He said it was up to me to determine which method gave me the tightess sync. The problem is that neither way seems to be working since the DA7 will not switch sample rates automatically to suit the sample rate of the song in Nuendo. I'm current only using 2 of the 3 AES cards that i currently have installed in the DA7. I would have to buy another Lynx AES-16 card to give me access to the DA7's 3rd AES card. I currently have 16 tracks of audio passing both ways btween the DA7 and the AES-16 into Nuendo. I heard a vague comment somewhere that I should maybe have two of those channels set aside for sync via AES cables, is that true? If so, how do i go about it? Using Clock and an external BNC cable would have been simpler.

I don't know if that's true about the 2 channels. I don't think it should be.

I think what Paul meant was that the Lynx card is always outputting clock through the cables when it's the master however, syncing via AES won't happen automatically unless you lock the DA7's clock to one of the card slots. What happens when you do that?

"syncing via AES won't happen automatically unless you lock the DA7's clock to one of the card slots. What happens when you do that? "

Yes, but how do i do that? I can't seem to find it in the 7's manual I find vague references but nothing in the way of instructions that i can follow.

If you look at the manual, Page 12-7...
Go to the Digital I/O -> Input Set window.
Once you have your AES card in, and it is talking to something else, it should show Locked next to the slot. You can then choose that slot to be the master clock.

That did the trick...problem solved
