Cool, so I'd hook it up like normal, speaker cord from head to cab, and xlr out of my head to the board, no DI box needed? In this instance a DI box would be optional....I may still pick one up anyways, seems to be standard bass player gear. Trying to up my game. Thanks.
Yes, option one is too use your XLR out on your amp, like always.
Some benefits of a DI box:
1 You protect your amp from a sound man applying Phantom Power to it. (it happens)
2 You eliminate Ground Loop noise. I had an Ampeg that sounded fine live, but when I listened back to the recording out of the board, It hummed and introduced noise I did not want into our live demo.
3 You provide a consistent line level to the mixing board when working with sound technicians (They like that stuff, even if your amp provides the same line level, the tech will like to see a DI box)
3a When you occasionally run across a picky sound tech, who demands a DI box, it eliminates an argument 30 minutes before you go on a multi band festival performance.
4 A DI box provides you insurance that you can complete a gig should anything happen to your amp during a show.
Again, there are several threads about this subject. Some guys use them, some don't.
