EMU 1212 schematic and mods help

realrift · 16th March 2008, 04:17 AM

Hi guys,

I have an EMU 1212M sound card outputting a S/PDIF signal via coax to the SFD-2 dac. I have done a bit of reading about this card and some people have upgraded the pulse transformer, caps and adjusted the output to true 75ohm. My questions are:

1) does anyone have a schematic for this card?

2) Does anyone know what parts would be good to use? Pulse transformer? Caps?

3) How to set the output to true 75ohm?

Thanks,
Rift.

Most of the guys around here are using analog out - these mods apply more to the analog board:

Post #9 in this thread has some more detail on digital, maybe you can email foo directly:

Thanks for the info Sangram. The post by foo does look to be along the lines of what I need. Unfortunately as I have only recently joined, I can't send any emails to other members

Cheers,
