Trying to connect SPDIF output from 4:1 MUX/Receiver with SPDIF input from Geek Pulse DAC/HPA I get no connection. Seems like Geek's input needs higher SPDIF voltage level. I changed the voltage divider R2/R3. R2 = removed R3 = 0R I get signal level 3.3V P-P when not conneced to Geek and 1,3V P-P when connected to Geek. Seems to work fine that way. Is it correct to do it this way, or should a SPDIF level converter be used? Regards Martin Edited by user Friday, April 3, 2015 9:01:40 PM(UTC)

Sounds like the Geek has a very low input impedance - it i expecting consumer level or CMOS(3.3V)?

Sorry the description was wrong. I had tried so many different things so I was quite confused. It is not the Geek causing this "problem" ist is a miniShark DSP from miniDSP.com which is expecting CMOS (3.3V). I solved it with a level converter. btw. what are the original values R2/R3 (schematic on website is out of date) Regards Martin Edited by user Wednesday, April 15, 2015 12:26:35 PM(UTC)
