Bobby,

There are so many options that's one of the nice things about the L1 system. I personally purchased two L1 systems with four total B1 modules and I am very happy with the system. I will admit it took a little bit of time to get used to the system but I love it more and more every time I use it. I have only had my system for about 3 months now and it's already seen a lot of use. I wouldn't hesitate to recommend it to just about any DJ.
