(Live sound) DI box? Is it needed to send the Line out from Blackbox to FOH?

I see. Thank you for the response. Is there a cheaper solution than buying like 5-6 DI boxes if I'm sending out a lot of synths?

DI box? Is it needed to send the Line out from Blackbox to FOH? I’m thinking about sending multi-outs to front of house and am wondering if DI boxes are necessary. I think the BB is line out on for it’s outputs. I read somewhere that many synth players...
