What kind of speakers for this mixer?

Hey guys I am a noobie DJ just starting off. I just ordered a Numark m101 USB Mixer and 2 Numark NDX400 Scratch CDJ’s.

Now the mixer just has RCA inputs for speakers. Would some KRK monitor speakers that have a connection for RCA but it says “Unbalanced” work fine with this mixer?

Any powered speakers will work with any mixer as long as you have adapters. And yes KRKs work fine- all RCA is unbalanced.

What does unbalanced mean?
