Convert SPDIF coax to ADAT optical?
Without going through a sound card in a computer, I'd like to:
- stream SPDIF coax (really an RCA connector) output from one machine... to: - two channels of an 8 channel ADAT optical input on another machine. Being able to select the pair within the 8 channel ADAT stream would be nice, but I'd settle for fixing it to channels 1 & 2. Is there a utility box that will do this and is "relatively cheap" and okay, or need I be concerned about introducting jitter with a cheaper box? (That is, on the ADAT side will a well-clocked D-to-A correct any timing problems that might be introduced by this configuration? Thanks in advance, Frank Stearns Mobile Audio -- |

There are a lot of boxes to do this, but the RME ADI-8 DS is inexpensive and well designed. The Studer D19 rack can do this also. The quality of the lightpipe connection is so poor that nothing else you can put in the path will even approach the jitter resulting from the lightpipe link, so don't worry about it. --scott -- "C'est un Nagra.

Is there a utility box that will do this and is "relatively cheap" and okay M-Audio made something like that called SAM. Of course you can't buy a new one, but you might be able to find one in the bay swimming with the sharks. "Converts S/PDIF to ADAT as follows: Left channel to all ADAT odd channels and right channel to all ADAT even channels" The literature that I have doesn't indicate whether the S/PDIF port is optical or coax but from the illustration in the manual, it appears to be coax. http://www.m-audio.com/images/global...SAM_Manual.pdf |

It ain't "relatively cheap," but I just read about a new box from TC
Electronic that may do just what you're looking for. List price is $1750, IIRC. http://www.tcelectronic.com/Default.asp?Id=11320 e In article , Frank Stearns wrote: Without going through a sound card in a computer, I'd like to: - stream SPDIF coax (really an RCA connector) output from one machine... to: - two channels of an 8 channel ADAT optical input on another machine.
