Behringer XENYX X1222USB Mixer (Tri Connect Test)

I had someone ask about if they'd be able to use multiple inputs in a single channel, and to put it plainly the answer is yes.
theoretically you should be able to connect something into all 22 (counting the XLR Connectors) inputs, if you have to means or the need.
But it would still advise against this. i can't imagine the strain it could put in the circuitry on the mixer.
Anyway as an example and test, I use all three inputs in channel 1 for this video.

to loop the effects peddle into any channel of your choice by using a single TRS 1/4 to a double or split TS 1/4 (you can find these readily on amazon). You connect the single TRS into back of the mixer as there is a single input jack for each of the channels then connect both the split TS jacks into the effects peddle tip is send and ring is return

I’m not entirely sure what your trying to do but you’er making some great sounds mate. I might run the video through Koala sampler and pull a few sounds off :)
