Hi!
I got one of those evaluation board a while ago and decided to hook it up yesterday.
The EVM is connected via AES/EBU to a RME MadiFx. The EVM is the master clock (I discovered that "Master Clock" and "Word Clock" are not the same thing...)
When it initialse, before any signal have passed through it, the mixer in Totalmix shows an input noise of -107db on both channels.
Then when I feed signal through it all is good, but when I stop the input signal (I even disconnect the xlr cable) the "idle" input noise of the EVM hang around -89db.
If I reset both switch on the EVM the noise floor drop back to the initial -107db.
What is happening? Is there any thing I can do to avoid this behaviour?
Thanks!
