SPDIF - RCA to BNC cables ?

Posted by: DIL on 17 November 2002

Hi,

I am interested in taking streaming audio (eg BBC radio via the web) from PC to my main system. I have an SPDIF output (RCA) and a mini-audio jack output. The DAC to be used is a Linn Numerik (BNC input)

Am I barking up the wrong tree ? Is SPDIF just for the output from the PC's internal CD/ROM ?

I have done a search on SPDIF but none of the hits seem to address this.

SPDIF is the data format, it can go via all sorts of electrial sockets, mainly phono, bnc and XLR

I have made leads to get the following to work :

Marantz DVD (phono) - Linn Numerik (bnc)
Marantz CDR (phono) - Linn Numerik (bnc)

Linn Karik (bnc) - Marantz CDR (phono)

Linn Karik (bnc) - Ego-Sys WAMI Rack (phono)

Linn Karik (phono) - Musical Fidelity X-DAC (Phono)

All worked fine.

The only one I wouldn't get to work was

EGO-Sys WAMI Rack (phono) - Numerik (bnc)

but I think this was more to do with getting a digital lock on the signal. I have not found the Numerik very compatible with digital sources. It is O.K. with the Karik though!

The easiest way to go is to make a lead is to buy the right length digital interconnect phono- phono, with not too big a cable diameter, cut off the right end, taking account to the directionality, and solder on a 75 ohm bnc plug.

Another factor to worry about is the SPDIF output format of the PC. If it is a Creative soundcard, it might be 48Khz, but this should be automatically recognised by the Numerik. If you can switch it via software/ configuration I would go for 44.1KHz, for optimum compatibility.

Good luck

You can buy BNC-phono adaptors from Maplin and elsewhere, these do the trick if you have a phono/phono cable.

I connect my PC to my Numerik, but I made a long cable for the purpose.

Whether the S/PDIF output on your PC is 'parallel' to the analogue sound output, or whether it's separate and will need configuration I don't know. You could explore the relevant control panel applet.
