Coax input fail with Audiophilleo DDC


#1

USB and Bridge input are fine.



Use USB>>Audiophilleo>>PWD MK2 and set input to coax , have no signal.



Anyone know this problem ?





#2

Specifications of Audiophilleo

#3

Does the PWD coax S/PDIF input work with other sources?


#4

I have to buy a coax cable to try pci-e sound card s/pdif coax output, make sure PWD coax S/PDIF work.



Maybe Audiophilleo +/- 0.3V amplitude let PWD loss signal.



Is PWD coax receiver need +/- 0.5v amplitude?


#5

The S/PDIF spec is +/- 500mV. 300mV seems low to me. This may be the problem as 300mV is 40% lower than spec.



Hopefully someone from PS Audio can help.


#6

Audiophilleo 300mV works on other DAC like Luxman DA-200,W4S DAC2 etc.



I know PWD focus on I2S,USB and Bridge. I use USB for PC and Bridge for NAS.

Coax input just for test.



Maybe next time PS Audio can choose a better receiver for coax.


#7

I am not aware of anyone else ever having a problem with the RCA input on the PWD. I doubt it is the PWD.



It probably has something to do with the setup you are using. I am only guessing that the level might be an issue.



Have you tried your particular Audiophilleo, set up the same way, on a different DAC?

My PWD MKII works fine with Squeezebox Touch and NAD T562. The only problem I had was with the bad SPDIF coaxial cable which i found broken :slight_smile:
