GK MB200 and Laney RB410 compatible?

[RedShec66]

Im looking into getting my first amp and cab setup and have been thinking about getting the GK MB200 and the Laney 410 as they fit into my budget and should have the power that I need. The only issue is that I have noticed the both have different inputs. The GK MB200 has the standard nl4 speaker input whereas the Laney RB410 has a 6.3mm audio input, similar to that found on you guitars and basses. I was just curious as to whether or not they are compatiable and its just the case that I will have to get a cable with one connector on one side and the other on the other side. Sorry I know this may sound like a really dumb question to some but I am still a relatively new bass player and havent looked into amps much
