002R wont recognize SPDIF from G5...

[rjd2]

hi folks, hoping someone may have some help for me. specs:

i am running PTLE 7 on powermac G5, 002R, apogee rosetta 800.

i recently got another powermac G5 to run my sample libraries from; i have connected its optical out to an optical/coaxial converter, and have that going to SPDIF IN on the 002R.

in session, i have changed the "hardwareptical" setting to SPDIF. and yet, when i assign tracks to "input:SPDIF L(or R)", i get no signal at the input.

i have the source comps hardware settings changed to OPTICAL OUT, and im sure its sending signal.

what am i doing wrong? thanks for the help!

Does the 002r not have an optical input? Why are you converting the optical signal to spdif? Also, does your spdif converter take adat optical, or only toslink?

[rjd2]

the 002R DOES have optical input, but i currently have it linked to the rosetta 800. i need a way to record from the auxiliary G5 w/o rearranging optical plugs in my rack every time, thus, i bought an optical to coaxial converter.

i am not sure if its adat, or toslink....ill try to find out from manufacturer.

so it at least sounds like ive got things plugged in correctly, and the session set up properly? thanks for help!

so apparently it IS toslink. am i to assume thats not what i need? great...

EDIT: would this give me a SPDIF output?

That add-on card is for an ASUS motherboard. Doubt it would work with your G5.

Toslink is just a connect, not a protocol. I believe the output on Mac G5 is S/PDIF.

A quick google yields THIS.

Something like this would be in order; Monoprice. I have no idea if those work, though.

thanks for the help, getz76.

that linked item is EXACTLY the outboard box i have. when i have it plugged into the SPDIF input of my 002R, i can open a PT session, and select SPDIF L or R as an input; i dont know if that means its being recognized or not. however, when i send signal from the aux G5, i get no signal at the track input when in record mode. if TOSLINK and ADAT are not formats of OPTICAL lines, then in theory, this should work.

any thoughts on if i maybe have the session set up improperly?

[getz76]

ADAT is a format. Toslink is a connector. S/PDIF (Sony/Philips Digital Information Format, if I recall) is a format that can be either digital coaxial or optical (Toslink).

So, let me just make sure;

1. Power Mac G5 Optical out -> (2.)
2. Toslink Optical to Coaxial Digital conversion box -> (3.)
3. 003R's S/PDIF Coaxial IN

If that is the case, there should be no need to set your "Optical" setting to S/PDIF. That would only be necessary if you wanted to run the Toslink from the Mac directly in to the Toslink (ADAT) IN on the 002R.

Can you give us a screenshot of your I/O Setting's Inputs page?

Also, make sure the output of the Mac's sound in the system preferences matches your session (assuming you are doing 24-bit/48kHz, that should be your selection).
