Hello, I have an original AudioFuse and have upgraded to firmware 1.2.3

I am seeing a phantom left level signal of approximately -36 dB on Phono Line input 3 in the Control Center (see screen shot)

Does anyone know why this is happening? It may of appeared since upgrading my firmware. I don’t really hear anything unless I crank-up the input, but I would certainly LOVE to get rid of this phantom meter displaying on that input!

HI @peejaygee and welcome to The Sound Explorers Forum!

Most logical question is, do you have anything plugged into that Phono input?

RCA Phonos are pretty noisy in comparison to balanced XLR/TRS .

HTH!

After your reply, I unhooked the AudioFuse confirming nothing was plugged into the phono inputs 3/4. I then connected the unit to a MacBook from the MacMini (both M1), only to confirm the same problem with nothing connected to the AudioFuse.
