Rolls MX122 MiniMix Pro Mic/Source Mixer

what type of imputs does it have? can i hook up my bass, michophone and computer then hear all through a headset without additional equipment?

Hooking up an outdoor theater do i need this 5mixerplus powered speakers and a receiver with hdmi for blu ray movies for this to work?

Can you use this with active, powered studio monitors? What cables would I need?

Can this mixer power speakers without amplifier?
