ADAT setup

HI everyone.

I have recently switched over from steinberg/windows platform to mac osx / logic pro 7.2 and must say I have never more happier.

The audio interface is the digi 002 running on MAC OSX tiger with CoreAudio driver.

Excuse my ignorance but I am trying to get an ADAT signal into an audio track in logic. I am running ADAT signal feeds from the focusrite octopre (just 1/8 (48/96)) into DIGI 002 ADAT IN.

In logic, I have created the audio objects in the environment. As an input source surely I am able to select ADAT 1/2/3/4/5/6/7/8 IN for record for that specific channel? Do I have to use busses to control routing rather than a direct in? Surely its possible? I have gone through the manual extensively, maybe I am missing something at this alarming pace of setting things up...

What do you propose or recommend the best connection setup would be in my case using focusrite octopre platinum with digiboard, digi002, 01v96?

I have also a VAMP guitar & bass processor I need to link to 01v96 but will use auxillary busses for that, but again, I need to get digital signals into logic 7.2 from the focusrite pre.

I come from a total analog environment into digital... getting to grips with the new tech.... slowly. oi.

Any help would be greatfull.

What sample rate are you running? If it's 96k, the focusrite is S/mux out on the ADAT cables, so the 002 won't know what to do with it. If you stick to 48k then just plug them together, set your Digi core audio pref's to lock to ADAT, then create input objects in Logic. The ADAT channels should show up as 9-16.

How many input choices is Logic showing you?

Do you see all of the 002's inputs?
Typically the analog inputs are 1-8 and the digital inputs come after that.

hi guys, thanks

i did have the sampling frequency set to 96khz, but am now trying on 48khz/24 bit to get things going. now here's an interesting thing S/MUX? you mean I cannot send 96khz over ADAT from the focusrite? or should i use the 25pin d-type?

in logic i get inputs 1-8 reserved for analog, i presume 9-16 for ADAT and 17-18 for SPDIF. (that is how it shows up in pro-tools le 7.1.1. I/O settings. all in all i get 18 channels of inputs but there is no signal meter-reading in the channel-strip's level meter..

which brings me to the point of creating an audio object (like mentioned) where signal can be routed to appropriate logic channel.

I created an audio object and chose input 9 through 18) just to be safe and now should get a signal but still not.

there are two mixers, environment and global. as i create the audio object it shows in global.

still no reading, any ideas?

ok any ideas?

ok.... i managed to record on input 9, just have to setup the 01v96 to route the input 2/3/4/5/6/7 of the desk to the relevant ADAT channels. funny thing happened...

although they say you wont have to install protools basic, just the update.... well i uninstalled and reinstalled with the upgrade and cs update.

thanks.

You can send it, but the 002 doesn't support it. You can send 2 channels digitally at 96k using the spdif port though. But for ADAT and the 002, it's 48k max.

Correct.

all in all i get 18 channels of inputs but there is
no signal meter-reading in the channel-strip's level
meter..

In arrange, select an audio track, set its input to the desired channel, record arm it. You should be good to go "IF" you've set your 002 clock to slave to ADAT or spdif, whichever you're using, in the Digi core audio manager.

ADAT protocol has a max sampling rate of 48k
So you can have 8 channels of 44.1 or 48K.

Smux is not supported in the 002.

That is where you can have higher sample rates with fewer channels.
(4 channels @ 96K)

The optical connector looks the same, but unless the device supports smux
48K is the highest sampling rate supported by ADAT.
