Can't get SPDIF through 50 ft of wire!

50ft is how many meters?
My interface did 13 meters......
You enlighten them Jocko!

Ok.......so you need a pulse transformer to break up the ground loop.

If you put it on on the RX side, you can use it come up with a differential output to the RX chip.

Newava makes a good one. Pulse Engineering is ok. I do not like the Scientific Conversions models, despite all their hype. Whatever you do, make sure that it is a 1:1 model.

I listened to this advice and obtained excellent results with Newave S22610. Thanks Jocko.

S22083 looks very promising as well.... I haven’t tried it.

I did try S22133 and compared it with S22610. S22133 was noticeable worse.

Make sure no DC goes in to primary winding.

Hi Extreme Boky

may i ask where you got the Newave S22610 and how much??

I assume its some sort of matching transformer.

Cheers

DigiKey, search by part number: S22610

Didn't I also point you to a good buffer stage, to go in front of the RX chip?? Maybe it was another guy.

Newava S22160 available from digikey amongst others.
Combine this with a coilcraft common mode choke DLF2000L to reduce noise from the computer.

Works well in my system although the cable between the computer and my dac is only a couple of feet.
