Hi folks, i just ordered a BH 500 head to pair up with my eden 210 XLT cab. I was reading the BH 500 manual, and i found this: My eden cab has only jack conncetion, and i have a speakon-to-jack cable that i plan to use to connect it with the tc electronic head; i don't understand why this could lead to a short circuit... Can someone enlight me? Are TC Electronic amplifiers designed to work only with speakon-connected cabinet? Any help will be much appreciated! EDIT: i searched on TC electronic's web site and i found this: http://tcsupport.custhelp.com/app/answers/detail/a_id/3235 So, problem solved!
