Recording From Digital source

Well, I couldn't find a manual anywhere online for this product, but typically if you use the digital IN you also have to use the digital OUT, not the analog outs. Check your manual.  

Sorry, Dave is wrong,
The input is a input just like any input. The only difference is the interface does not do the conversion. It only converts the connection from RCA jack to a USB. So the sound is output from the UBS . 
 I use the digital in all the time. It will ( should ) be at the bottom of your input selection list for the track. If it is not then  you need to use the ASIO drivers.

The SPDIF output is to use for things like  studio monitors that have SPDIF input or to record to a DAT or digital recorder , or in my case to a digital mixer.  It can be used concurrent with the analog outputs, It will have it's own faders in concol veiw if active.   

On my M audio interface you had to choose the SPDIF in the M audio control panel to make it work, It shut down the 3/4 analog output.  

I'm also assuming you understand that the digital device your patching to the SPDIF input is output at 44.1 too, You will get a warning asking which device is the master clock if not.  
What is it your trying to patch in, A CD player or Mini Disk?  

I used to have that interface. It only supports optical (ADAT) data inputs. What you need is a S/PDIF to optical converter, which I believe set me back about $40 with cables. 

Thanks Guys very helpful - I will try tonight - the inputs are balanced jacks/RCA on the back and Optical - I am connecting a Minidisc Player using a fibre Optic cable Optical out to the optical in on the SPS 250 (same as Edirol UA25 from M Audio by Roland just Cakewalks version originally bindled with Sonar but now upgraded to Sonar Producer)picture is here http://www.rolandus.com/products/details/704

It is a shame that Sony still has not made it possible to do a direct hi speed transfer via USB from Mini disk back to a PC. Letters have been written by the thousands. Because it is a dead format there is no desire to even make a hack of the protection codes. 
The request is that only analog source recordings be made transferable. 

I still use mini disk as a back up when I do live PC recordings and this means I have to transfer in real time anything I needed. Thank goodness this has been a rare case. 


A little bit of reading about what is actually output from the digital cable had me pondering the fact that there can be a few clock and bit rate formats depending on the recorder and the ATRAC system used.  A CD player is easy, it's always 44.1 / 16, but Mini Disk is a different animal. 
I think it might be best to record directly to a wave editor like Wave Lab, Sound Forge or Audacity which is what I have always done. Sonar might not like a odd ball clock/bit rate. 


I have never had to do anything special, I hook the optical cable into the SB Audigy TOS input and then select that as the recording source in the Audigy's mixer GUI. Wave Lab would record it as a 44.1/16 bit wave which is what my deck must output digitally. Sony  MDS JD 530 

Thanks for posting the picture and I see that you might have to also select the digital source on the interface. If there is a GUI ( software) mixer for the interface you will possibly have to set that too. 

As my interface uses SPDIF , I'm not sure how a TOS link digital in shows in Sonar, must be the same. The only difference in the data is that SPDIF cannot transfer the Serial copy protection but TOS Link does,,, that's why Sony used it.

Be sure to order a TOSLink cable, too.

Hey Bit, He won't need the converter. 
His Mini disk and his Interface both use Tos link. 

His problem will be activating the digital input as a source and/or clock rate sync.
