Reply to Do i need to connect an amp to my audio 2?

I have one laptop and im connecting the audio 2 to that. i also have a 3 channel mixer out of which 2 channels i will be connecting to my audio 2 (also is there any way i can connect all the 3 channels or atleast use the eq knobs for other functions on traktor i.e effects etc).

So now do i need to connect an amp to my mixer for it to produce sound or can i simply connect speakers to the mixer and it'll play? Also what do you mean by self powered or not self powered speakers?
