Rosetta->001: which connection type would be best?

[GapeOne]

All,

I picked up a Rosetta 96KHZ 2-channel A/D and would like to know which connection type would yield the best performance (i.e. XLR, SPDIF, etc..)?

Thanx in advance!

Spdif....... If you use XLR, I think you would be going through extra damaging conversion.

I dont have the APogee but that's what I am using on my converters.

Damn! That's right. I forgot about the 001's crappy converters (which is pretty ironic since they are what lead me to purchase the Rosetta in the first place... lol).

Thanx!

>you don't specify what model Rosetta..
However, if it is used for A/D conversion in front of PT LE hardware , SPDIF on coax will work.
Not sure if ADAT optical is available on Rosettas, that could also work..giving 2 channels of either SPDIF or ADAT format.
75 ohm coax is preferred for clocking reasons over the optical. Besides, no PT LE hardware can receive above 48Khz over the lightpipe port, using ADAT opt. protocol.
The XLR you have mentioned is a true 110ohm, transformer balanced digital connection, referred to as AES/EBU.
So...SPDIF for you, on coax..

It depends on what else you use;
-You can use the optical as ADAT and still have your RCA SPDIF available for something else.
-You can use RCA SPDIF and have your optical available for ADAT.
-You can use the optical as SPDIF dut you will lose the RCA SPDIF.
Remember you can't use two SPDIF's at the same time.
The AES will be used when you add a DAC, it will allow your DAC to hear the ADC while it feeds a signal to the 001 without monitoring through the 001's converters.

I just updated which Rosetta I purchased above. Sorry I left that out...

Also when you do connect your Rosetta throught SPDIF go into your DIGI settings and select the clock to come from SPDIF. That way you will clock off of the Apogee which will be better than the 001 clock.

What do you mean? I don't use anything else. Just a mic and an MPC as I'm still building my studio..

Will all of these yield the same quality?

Why is that? Lemix mentioned 2 channels of SPDIF. Is this not correct or is it correct, but I can only use one at a time???

Thanks for the insight. Though the D/A will come later it's really nice to have all of this info in one place.

Hey GapeOne ,

Why is that? Lemix mentioned 2 channels of SPDIF. Is this not correct or is it correct, but I can only use one at a time???

It simply means, that only the RCA (coax) or the lightpipe (ADAT) connectors can receive the SPDIF stream. Never both at the same time .
" 2 channels " of SPDIF is just that ...stereo signal into either the RCA or ADAT ports..
1 cable/1 connection...=2 channels of audio

happy tooling,

It can only be a stereo signal? Can I not use it as 2 mono signals as I don't have a stereo mic?..
