I'm using Nuendo 1.5.1 (w/Steinberg's 96/52 interface card) with my DA7 desk. I'm running 75 ohm BNC cables between the DA7 and Nuendo with the DA7's clock set to internal. There are no other digital devices in this line. Yet I am still getting a considerable number of clicks and pops during tracking.

I have been advised on the Nuendo Bulletin Board to purchase an Aard Synch II card. But I have also been told that the RME 96/52 card is stable enough to not require the other clock. Since this is a 2 way street, I thought I'd ask you guys how stable the DA7's clock was? Do I really have to by an external master clock for such a simple set-up?

I am also using 2 96/52 cards (Which I'm assuming are actually RME card?)
I have the DA7 set to internal and then a cable from DA7 to a T piece for each card.
The last card has a terminator on it.

I have no problems with this setup which has been unconditionally stable since its first connection.

Check your cables and terminator.
My guess is you don't need an external wordclock.

Hope this helps

I'm also using Nuendo 1.51, however, I'm sliding into homeplate thru a MOTU2408mkII. Using TDIF cards in my DA7, and apogee 110 ohm wordclock cable, I have made the computer the clock master...I find less interference(clix & pops), and more stability. Keep in mind, everyone's system responds differently, due to any number of variables - try switching your word master, and perhaps you will resolve the noise. One other thing you might check, is that you have Nuendo set to the same clock rate as the DA7 - I've had software (cubase) change clock rate in mid - song, and send the DA7 into a tizzy...
just my 2 bits, envoid

It's not a matter of clock stablity, you don't have it set up correctly somehow. If you get pops it's not the clocks fault. The problem is somewhere else.

Keyplayer: I'm all ears. Tell me what to do.
I'm running 75 ohm bnc cables between the PC and the DA7. The DA7's wordclock is set to int. The termination switch is on.

The 96/52 card offers 3 possible settings for synchronization, 1) Autosynch, 2) Master, and 3) Wordclock. I tried Wordclock and got continuous noise ( like someone was making popcorn). I tried Master and got less noise, but still a healthy showing of pops and that ripping sound. Autosynch was the best of the 3. I can go about 2-3 minutes clear and then I'll get A click. I only get the ripping sound every now and then. But, so far, all 3 still give me some kind of aggrivation.

So tell me how to set it and I'll gladly do it and let you know how it turned out.

When you tried Master, did you set the DA7 to external (and maybe remove the wc cable going from the DA7 out, to the card wc in)?

Sorry if that's obvious but hey, I miss the obvious all the time.

Keyplayer: The manual says "WHEN THE WCK IN BUTTON IS SELECTED IN THE [D-I/O>INPUT SET] WINDOW, THE DA7 WORKS AS A SLAVE UNIT TO AN EXTERNAL CLOCK DEVICE."

Doesn't that mean that when it's set like that the card is in control? I hadn't thought about removing the cable. Do you think it's causing some kind of wordclock loop?

Keyplayer,
Proper cables, and short runs help to improve W.C. distribution in a complex audio environment. My buddy's would insist that either the DAW be the Master or that you use a Master Generator...however it seems that there is no exact way and experimenting won't hurt any of your components (except your speakers).

To make the DA7 the Master W.C. device you must select INT as the Clock Source and select the proper Sample Rate in the D-I/O Setup section of the DA7. Once selected the mixer will send W.C. sync (at the selected Fs) via the W.C. OUT (BNC) and through any of the other digital outputs and digital option cards.

The DA7 can be Slaved to W.C. Sync via the W.C IN (BNC), the AES/EBU/S/PDIF 2-Track IN and any of the optional digital I/O inserted into the DA7's card Slots. You could also Slave the DA7 to Ext. W.C. Sync by selecting (moving the cursor over) any of the option Card Slots that have a LOCKED status...or by selecting 2-TRK IN. Remember to hit Enter to execute the change.

The 75 Ohm termination switch on the DA7 should be selected to ON if the DA7 is the final device in the wordclock chain thats being connected using the BNC connector on the back panel of the DA7.

Good luck,

Hey Keyplayer,
Maybe this will cheer you up while you figure it out…

"i just discovered somthing nasty .. when i make my d8b the slave using the appogee via wordclock hooked to a motu 2408 .... i lose adat card 1 .. gone ... non existant yet if i revese the cable and make the d8b the master up it pops again ...... i thought it could be the motu yet none of my other devices slaving off the motu are having any trouble any one else see this ? i realy prefere my daw to b the master clock,,,, not the desk ,,,"
