Here's what I'm trying to accomplish- 4 channels onto 2 separate recorders using one clock so I can easily matrix;
mics>v3>microtrack>(digital link to AD2K) + SBD>XLR out>AD2K>microtrack
Never done this before so I don't know if my understanding of wordclocks is accurate, so please feel free to harshly correct me. :) After looking at the manuals it seems like it will work, but would love some advice. Might try this set-up tomorrow if I can do it.
Any advice?
Thanks!
Jesse ;D

from the ad2k manual-
The digital input will only accept digital audio signals, and will automatically
recognize either professional or consumer formats. It will not respond to non-audio
signals such as word clock, super clock, or video.
that's a no i take it?
-
yeah, I don't think you can do it, because neither the V3 nor the AD2K have word clock in.
-
I think it can be done. What you need to do is to put an RCA(m)>2 RCA(f) splitter on the SPDIF signal coming out of the V3. Send one side of the split to your first MT and send the other to the AD2K. You will need to have an RCA-BNC adaptor to plug into the AD2K, though.
I split the SPDIF signal from my Mytek192 to do essentially the same thing you're trying to do, which is to lock a second A/D converter (in my case, a mod MOTU Ultralite) to allow four channels on the same clock to two different MTs. Works like a charm for me.
-
Hmmm. Gonna give it try and see what happens. I happen to have the exact splitter and BNC adapter, surprisingly so I just rigged it up and tested to makes sure my MT saw the mic>v3 dig signal through that splitter. Worst case I just get mk41>v3. best case I get that and sbd>ad2k>d8 and it's synched. I don't have much faith in the D8, but if the clocks sync and it works I might buy a MT II for this application.
Thanks to Jason for sparking this idea in my head with his 4 channel d'elf set up. +T to you both!
Wish me luck.

Jesse - let us know how it goes. alternatively, you could easily do a 4 channel setup with one MT + one HD-P2. The tascam is great, because it has word clock in. not only that, but you can send the HD-P2 an S/PDIF signal, and tell the unit to only grab the clock info from the S/PDIF stream.

Cool--hope it works for you. With the D8 in the picture, I'd probably make sure the V3>MT and AD2K were at 16 bits. Not sure how well this would work if you mix 24 and 16 bits. Get that second MT and go back to 24 bits.
The HDP2 would certaily be an easier solution (heck, an R-44 would be much easier and cheaper than the Tascam, at least new), but you're probably getting better A/D conversion this way.
-
it can be done, ive ran this way before, just take the aes out of the v3 to the ad2k wordclock in, i beleive the light on the front will tell you if its locked to an external clock
dont forget that the input of the ad2k is reverse polarity. if you want to matrix with 4 channels using v3 and ad2k, make sure you flip pins 2 and 3 on the short xlrs to the ad2k (unless your v3 doesnt have polarity fix, in which case both signals would be inverted.)

Well I wimped out and didn't try it. ::) I was with some friends that were SUPER excited about hearing the tape so I didn't want to screw it up. I did get a great mk41>v3 tape that I am happy with though. In the future I'll definitely give this a shot, I had planned on upgrading to the MT II anyhow just for the seemless split ability. I would think a MT I wouldn't fetch too much these day in the yard sale, so I'll probably hang onto it and try to get this going. The thought of mics>v3+sbd>ad2k recorded onto 4 channels on the same clock is very appealing. And with digital outputs on both boxes the MTs seem like an easy, inexpensive way to capture the digital signals.
Now I will need a new audio editor with multitrack support that runs on a mac...?? Probably means another good chuck of cash.. :-\
Thanks for your help guys. +T's all around. I will try this out in the near future and report back!

if you want to borrow a 744t let me know. obviously, you pay shipping both ways.

You're awesome, Ian.

what was confusing me was that it's not called an "word clock" input (which is why I never tried it the times I've used an AD2K).
but straight from the manual, at the bottom of page 5, it says:
A digital audio input jack allows the AD2402-96 to phase-lock to an external AES or SPDIF digital audio reference. Most 2-channel applications will not require an external reference and many users will never need to use the external reference input. However, the external reference is provided to allow phase-accurate multi-track recording with two or more AD2402-96 converters.
and then on page 12:
The “LOCK” LED will turn on whenever the AD2402-96 is locked to a reliable digital audio reference of the correct frequency. The digital input/reference signal must be AES/EBU or SPDIF.
If the lock light is off, the AD2402-96 is operating as clock master (using the internal crystal reference).
so there you go. the key thing, when syncing the AD2K to the V3 clock is to NOT use the word clock output. the manual says that it needs to be AES or S/PDIF for the digital lock. the good thing is that the V3 has both S/PDIF and AES ouputs, so whichever one you aren't using to send to your record deck, you can use the other one to the AD2K to get it all sync'ed up.

Connected AES out from V3 to the digital input on the AD2K and bam! lock led on the 2k flashed for a few seconds then stayed solid and lit. Awesome. Got the second microtrack today at Guitar Center for 240. Not too bad! I might sell my MT1 and buy another 2. The other great thing is I have an easy way to run a backup for those "must not screw this one up" type nights. ;)
I'm going to tape The Brew tomorrow night and see if I can do 4's>v3>MT1 + sbd>ad2k>mt2. And apparently I can use Sound Studio to do the mix down which I already have. This is such an awesome feature about my setup that I didn't even realize I had! ;D

that is sweetness jesse :) let us know, and hear, how it went ;)
if I were you tho and you started to do this more often(which you should), then id get an r44 in a heartbeat. i saw rob clarke's at moedown and it is TINY compared to the r-4 :) just need cf cards :) and i bet its battery compared to the r44 is alot better.
but, you are golden w/ what you ahve. very cool. ive never messed w/ word clocks, but that is supa cool IMO :)
-
Yeah I think I'm pretty golden as is. The Microtracks are ideal for taking digitial inputs, and they are super small and lightweight. With the V3 and AD2K the last thing I need is a bigger recorder in my bag! And there is NO way I'm ditching the V3 or AD2K. It's just my ideal setup. Sound quality is more important than convience to me.
Can't wait to try it tonight at the Iron Horse. Hopefully, I can get a patch. I'll keep you updated.

Well ???
-
Ha! :D
Everything went perfect. MK4(DIN)>KC5>CMC6>V3>MT1 + SBD>AD2K>MT2 (synched from V3s AES output). It should be a killer tape, because I just listened to the two tracks off the soundboard and it sounds great as is, very well balanced. It took some finagling to get the board patch, because apparently it's against the Iron Horse's policy, but the FOH was very cool and hooked it up just in time to get the whole thing 4 channels. Should be cool. More to come after some sleep.

This is really a great idea - gonna have to give it a try with the AD2K+ and my Mini-Me

With you all the way. I could never give up my AD2K+. You should hear it with the PSP-2 in front >:D

I bet!!

But you did give up the ad2k+. I thank you for that everytime I record ;)
