where do I monitor optical input on the digi 002 or pro tools7.4.2

[dbluprecords]

I am getting to much noise from a synth through the line inputs, so I am trying to go optical. Where is my signal?

Optical from your keyboard is probably optical SPDIF. You would need to go into Hardware Setup and select Optical=SPDIF, then go to the I/O setup>input tab, and enable the path(Add Path, make it stereo and click in the boxes for 17&18). Then probably go back to Hardware setup and select Optical as the SYNC source. Now having said all that, I suspect that your noise is an issue that would be solved by some troubleshooting. Running the keyboard volume at or near full up is a good start. Then running the outputs into the 002 on inputs 1 thru 4 with quality cables, no more than 15' long. If you need longer distance, run short cables from the keyboard to a pair of direct boxes and use mic cables into 2 mic preamps(if the DI boxes have pads, make sure they are off).

Unless it's an Alesis.. My QSR uses ADAT outputs.. Would be helpful to know what the OP's unit it...

Optical inputs are ADAT 1-8 as Pro-tools defaults (accessed through the setup menu).

If your devise has a stereo optical out this will need to be converted to a SPDIF signal to be connected to the SPDIF in on the back of the 002R (002's only take ADAT optical NOT stereo optical). The CO2 is a good converter, but there are loads out there.

? SPDIF is available on the optical connector...

Correct. No converter needed.. Unless you need the ADAT and SPDIF at the same time..

Cheers for that.

Help!
I'm using analog Mic and Line inputs to record through my 002, while monitoring through SPDIF output (RCA) into a digital crossover on an active speaker. Everything works and sounds great.

When I hooked up my Alesis QS 8.1 synth via ADAT into the optical input to record, I discovered that I could not monitor the output of the Alesis while recording. I'm getting the signal into Protools, and can hear the tracks upon playback, but I can't listen to the ADAT tracks while recording.

Can anyone help me figure out why I can't hear the ADAT input out of the RCA optical SPDIF output while recording? It's quite difficult to record on top of other tracks if I can't hear what I'm playing!

What am I doing wrong?

you're mixing up terminology here... RCA means copper wire not optical..

The other thing I am not clear about is..

Are you recording MIDI or Audio from the QS8? If you are recording MIDI then you need to have MIDI thru enabled in order to trigger the QS. Local control should also be OFF in the QS..

Explain a little more clearly exactly what you are doing.. Type of tracks etc..

Hi Flommer, I finally figured out why I couldn't monitor my 002's SPDIF outputs (using RCA copper wire cables going into the SPDIF RCA inputs of my electronic crossover's input) while recording my Alesis QS8.1 synthesizer plugged into the 002's ADAT optical input.

I went back to the Digi 002 Manual (after putting it away for the past few years) and discovered that you can use either RCA or optical, but not both together. I feel like an idiot: when in doubt, read the owner's manual, etc....

Since I want to monitor the ADAT optical input of my Alesis while recording, the obvious method is to use the Main Analog Outputs to monitor the signal, using conventional powered monitors.
