Hello,

The instrument input of my Fireface 800 is blown because of connecting my Korg polysix synth. I heard some loud crackling when inserting the jack and now the limiter led is always on and there's a constant hum and no input signal anymore. Also the output 1 is louder than the outputs 2 to 8 so now I can't use output 1/2 as master output anymore.

On this forum I have read a similar post from 2012. As an answer somebody from RME said the opamps are probably dead. I will have them 'read' by a proper technician but my question is: with which opamps do I need to replace the old JRC 4580?

Thank you, STEF.
