Can't get ADAT Optical I/O in Yamaha DM 2000 talking to 002 Rack

[redsearecordingstudio]

To maximize tracks I have 8 XLR mic ins going insert out from my Yamaha DM 2000 mixer and into my 8 analog 002 Rack line inputs. In the Yamaha I've patched channels 9-16 to my Waves Y56K ADAT Optical slot. I have the i/o lightpipe cables running in correct directions from the slot card to the 002 Rack optical i/o to get my other 8 tracks into Pro Tools. I've created new paths in my I/O setup in Pro Tools and designated each path accordingly with the optical ins. I've set up the Hardware options to Internal Optical I/O in the hardware setup. I've got a signal coming into my mixer lighting up the meter from the mic. But when I arm the track and try to record I get nothing....anyone?
thanks
Jason

Not sure why you had to set up new paths in I/O setup... Just renaming them?

Your hardware setup should be to clock via ADAT, not internal.. That's probably your issue. Make sure your sample rates are the same on both systems...


I suppose that if you are sending the 8 ch of ADAT out of your 002 and into the yamaha, then you could have the mixer clock to protools, but you didn't say that. Bottom line is that 1 device is the master and the other(s) slave to it.

since the 002 rack didn't automatically identify the optical ins I created new paths and named them. I restated everything with a different sample rate (48) on both pieces of hardware and pro tools now sees the optical tracks in but when armed doesn't get a signal....

Are you sure you have things routed correctly from the Yamaha?

Can you try to verify that you're getting optical out of the Yamaha by doing a loopback test?

[redsearecordingstudio]

Not sure how to do a loopback test since it's a expansion slot card...any suggestions. There are menus galore on the Yamaha. I do keep hearing a consistent crackle every minute or two come into my armed track in Pro Tools and at the same time in my mixing console...???

[JeremyPaulCarroll]

This may sound a bit basic, but have you actually put the transport into record in Pro Tools, or have you just been monitoring the signal while the track is record-armed?? It's a possibility that your track is set to Auto Input Monitoring, rather than Input Only...

Just a thought...

Cheers,

Jeremy.

"crackling" sounds like a clock/sample rate mismatch. Did you set ProTools to clock to an external ADAT source?

[DigiTechSupt]

I've set up the Hardware options to Internal Optical I/O in the hardware setup.

I think you need to set that to Optical/ADAT, so that Pro Tools gets clock from the Yamaha.

It's been way too long since I've used one of those boards, but I would imagine it has a way to route an incoming signal to one of those digital outputs so, if you loop an optical cable from the digital out back to the digital in, you should be able to send that signal out and it will come back in on an optical channel, which you can then monitor to see if you get input signal.
