Hi all
I recently bought a used FireFace 800. And there is one problem with it, the high frequencies are greatly attenuated. I took measurements using RMAA and am attaching an image. I can say that the problem is definitely in the output stages, since the sound in the monitors is also very “dark”.

Perhaps some of the capacitors have become unusable or something like that, I could try to repair the device. Can someone tell me what could be broken?
