Help with the different Mogami cables for analogue

[johnah5]

Hi I need to connect out of the DAC to the amp and can only use S/PDIF (RCA) connection.
Mogami has so many cable like 2534, 2497 and what I have is 2964!
Is one better than another sonically? My 2964 cable says "Hi Def 75ohm" which is the same as the digital cable I am using.
Should I get an "analogue" cable or is the ohm rating only important to digital connections?

Thanks

Only important to digital connections. And S/PDIF is so rugged that it usually doesn't matter.

Analogue line level uses impedance bridging instead of impedance matching, and therefore 2964 should work perfectly fine.

Mogami W2964 is an excellent 75Ω cable for use as an S/PDIF interconnect. The S/PDIF spec is fairly clear but the implementation in devices can be wide-ranging with signal voltages and impedances far outside of specifications yet they still seem to work. You'll be fine with what you have.

Thank you so no need to think about 75ohm rating when dealing with analogue signal? If the cable is working all is good?

Yes. Line level audio signal are far less demanding than s/pdif (much higher bandwidth), and on well designed gear the inputs are high impedance, meaning that practically any coax cable with sufficient shielding will function flawlessly in terms of audibility.

Thank all for the help!

IIRC it was a spec for analog component video rca cables.....

The 75Ω rating is the characteristic impedance of the cable—which would be of some concern for S/PDIF signal frequencies—but since the spec is so poorly followed and the short distances involved won't have much effect on the signal integrity, any cheap RCA interconnect still would work. As before, the cable you have is more than adequate for your needs so you needn't worry about it.

Shield cable don't really need to worry about. 2497 another shield cable. 2534 mic cable terminated like RCA. For me, still like single core.

Really wish your translator would work with english....
