I haven't been able to find this summed up in one post. Could someone explain everything about speakon? Things you need to think about when connecting. I've read about mono, bridged, 1+, 2+, 1- in different posts, but would like it in clear text. My setup is a GK 700 RB head and an Ampeg Portabass PB 210-H. Are there different kinds of speakon cables? Basically, what should I ask for in the shop to make sure I don't blow up my kit? Is it at all possible to use the bi-amp feature of the 700 RB with this cab or is that exclusively for GK cabs?
