My new zoom A3 pedal has Balanced XLR out and regular mono phono cable outputs. I am unsure which will give the best sound on my home system (Behringer acx450 Amp).

The box says use the balanced out to connect to PA systems but I don't know too much about the differences to be honest. Balanced out always gives the best sound ?

Any help appreciated as although I am a long time acoustic player, am new to effects and never used it with a PA system.
