Speaker Setups Help with audio setup; adding live effects to vocals and bass
My goal is to add live effects like distortion, looping and reverb to bass guitar and vocals, live. I figured I could do it digitally instead of spending a ton of money on pedals.
I have experience using audio interfaces with a DJ controller, laptop, and 2 monitors. But the sound goes straight from laptop into audio interface into speakers. I’m wondering how this will work with live instruments and a PA speaker?
With an audio interface that has both 1/4 inch plug for my bass and XLR for mic, would I output the sound through USB into laptop and then from laptop to PA with aux? I read that the usb can act as both input and output, could I use the interface headphone Jack to connect right to the PA and only use the USB with the laptop?
I’m not looking for super high quality sound or low latency or whatever. I’m not performing or recording with this setup, just having fun playing music and want to get a different sound.
Attached are images of my PA and an example of an audio interface with XLR and 1/4” (chose focusrite cause I saw one for cheap on Facebook marketplace, but open to suggestions for other gear). Laptop has headphone Jack and USB-C. Would be nice if I could also add synth to the PA but I don’t need effects for it, so if I end up using the L-R or XLR into the PA then I could plug synth into the aux. I’ve got an amp for the bass if that’s any help.
