I have been using an Mutec +3 USB for several years in my main system. USB in and AES out to my DAC. Mutec REF10 as external master.
I am trying out a new pair of KEF LS50W-ll’s and want to feed their coax input from the Mutec until Roon Certification is completed. I thought that it would be as simple as disconnecting the AES cable and then hooking up the coax to the KEF but I am getting no audio output. I have not changed any settings on the Mutec. I have chosen coax as the KEF input and switched the Roon app to point to my Audiolinux Roon Endpoint which feeds the Mutec.
The Lock LED MAIN REF is on, as is the LOCK RE-CLK REF and Audio LED.
The top three REFERENCE lights are on.
For MODE I have EXTERN and Re-CLK
