Connecting multiple inputs to one output

[Jack_213]

I want to have multiple inputs feeding into one output. would this mixer work? The outputs in question are Xbox, ps4, PC and my phone. all of which are regular 3.5mm jacks.

If you do, then buy the combo with the four adapter plugs. That mixer uses 1/4 inch mono inputs. All the outputs you mention are stereo.

IIf you don't want to listen to more than one source at the same time you can use an input selector rather than a mixer.

If you want to listen to more than one at the same time then you need a stereo mixer like this one

a four channel mono mixer would only allow two stereo sources and you would have to
adjust each channel separately
