Thanks guys, some really useful information here.
Can anybody recommend a small mixer? I don’t need a huge amount of channels obviously. Also, most of the mixers I’ve looked at seem to use a single xlr input on the channels. Does that work with my gear? (Do I just use a cable that combines the trs outputs from the A4 to an xlr jack, or do I need to use trs inputs to the mixer?).
Working with hardware only is a lot more complex than making computer music, but definitely worth it!
