The gain channel on my Bogner has a certain amount of hiss when nothing is connected to the input. This would be normal, as all amps I have do this on a high gain channel.
When I go out of the output 2 on My Axe Fx 2 XL, with unity gain, into the front of my amp on a high gain channel, I've noticed that the hiss increases a little. I've been trying to see if I can eliminate this slight increase. Last night I came to the conclusion that a certain amount of hiss increase is going to be unavoidable because there is two A/D conversions, which introduce noise, and then there is the fact that another electronic device is in the chain.
So I decided to do an experiment.
I have a Voice Live 3 by TC electronic, which has a guitar effects processor built into it. You can set it up so that it is in front of your amp. So I decided to put it in front of my Bogner on a high gain channel, in a unity gain scenario. Guess what? The noise was way way way worse. The hiss increased dramatically. It made me appreciate how little noise is being introduced by the Axe FX 2.
So, I believe some noise is unavoidable, and the little bit of hiss that is introduced by the axe in the 4CM is minor compared to other devices.
Side Note:
To get rid of the hum in the 4CM i did the following.
1. I made a really short humbuster cable and it goes from Output 1 to the return of my amp
2. I use a short George L TS cable from the send of the amp to the FX return on the Axe
3. I do not use a humbuster cable going from Output 2 to the front of my amp. I found it there was even less hum when I used ordinary TS George L cables and a Radial Bigshot A/B/Y between Output 2 and the amp input. I use output B on the bigshot with the iso transformer activated, and the ground lifted. I went with the Radial Bigshot because it has a very good iso transformer that does not impact the tone when activated.
If anyone knows of an even better iso transformer, that uses unbalanced connections, please let me know.
Good luck guys!
