Hi, I recently purchased a Radial X-Amp with high hopes on reamping.
I connect my X-Amp to the guitar amp and no noise... all is good,
then when I plug into the X-Amp's input from the Fireface's out (TRS>XLR) I get huge hum noise.
Thats when the ground lift is engaged, when its not it sounds like a jet engine.
Remember that this when I connect the X-Amp to the Fireface and no recorded DI's or DAW's are involved.
Any ideas?, I really want to get going with Reamping!

I've tried adjusting the output level on the fireface and the X-amp.
The output level on the fireface has no effect on the hum, but the output on the X-Amp will of course lower the hum, still you need it at least half way up to get a decent signal into your amp.
I haven't tried other cable because I don't have them :)
I'll try it in another house tomorrow, wish me luck!
Sounds like the common wire has come off, either your patch cabl
Sounds like the common wire has come off, either your patch cable of the unit. How is the ground lift cap doing? Are there any caps to common in the audio path? Is that passive box? If so they likely used this... as basic circuit.

Thanks for the pics!
Well we now know its not passive.....
I would think he would not be using a tantalum cap for the ground lift circuit.
The one closest to the XLR connector would be my guess, maybe the poly brown guy.
From what I see in the pictures nothing is obviously damaged.
Is it true that you 220V 50 Hz system for everything but this unit?
Yeah I've got a big converter for the 120V amp, I've plugged the
Yeah I've got a big converter for the 120V amp, I've plugged the stuff into the same outlet source, which didn't make a difference.
On other news, I tried using output B on the X-Amp and engaged the side ground lift of the X-amp, wouldn't you know it, all the hum was gone.
Still when I plug into Out A the hum comes back, I'll live with this for now.
Could be that you're sending the wrong level signal to the X-Amp

Try changing the output level for the Fireface in Settings.
You have three settings for both input/output levels. Not sure which one the X-Amp is looking for.
To cover all bases - check your cables, and also for ground loops.
