Hi all, 

Being a classical guitarist this is all new to me. 

I have katana m3, it says to plug the L/mono into the power amp in. The guitar into instrument 1.

To bypass the physical amp 

 

Ive set the 1/4 out level to line. 

I get a ghosted sound, very quiet, master volume is on full. When i take the end from "power amp in" plug it into the "input" its very loud, but not a neutral sound, as all the physical bells and whistles on the amp dominate. 

Ive been scratching my head for 2 hours, 

Any help please?

Have a look at the online manual for connections with the Helix Stadium https://manuals.line6.com/en/helix-stadium/live/quick-start

 

Plug the output from the Stadium L mono into the your Katana Gen3 power amp in to use it as an FRFR cab (powered speaker). Plug your guitar into the instrument input of your Stadium or if using a microphone to get your guitar sound then use the mic input.  The L mono output from the stadium into the Katana is the only connection it requires do not plug your guitar into the Katana guitar input connector.

 

Guitar into Stadium and its effects are then output thru the L mono to Katana and thats it!
