Maybe I could figure this out on my own but I’m sure it’s a pretty common situation so just wanted to see if anyone chimes in with some wisdom. I have a radial extc reamp box off of my mix out 4 on a qu32. The extc is mono in and out and has two loops for connecting guitar pedals, seemed like a fun box to have around to play with and so far it has been pretty cool when I send a mono source to it, but if I want to just send the left channel of a stereo channel to mix 4 what do I do? Do I have to unlink the stereo source? I guess I’m just not entirely clear how stereo channels are dealt with when they go out on a mono out. I don’t want to send a stereo channel combined into mono into my reamp box, but I also want to keep my stereo channel for the main mix. I’m definitely still an amateur at all this but I’m having fun! Well as long as I’ve kept my inputs and outputs in my patchbays connected properly. Always double check and mute and pull down faders before you make connections kids.
