Afternoon all! 
 
I'm after some advice on a technical question as I have nil technical knowledge..! 
 
I have a TC electronic BH550 and a couple of Genz focus 112 cabs, sounds great and a lot of bang for my fairly limited budget, suits me well... I also have a spare BH250 Head that I no longer use, I had thought about moving it on but someone suggested that I could put another cab on it and slave it up to my other head..... 
 
Is this a thick idea that could fry my rig or just sound crap? if not then how would I do it? Both heads have an XLR balanced out, could and xlr to jack run from my 550's xlr out into the 250's input and power a third cab? 
 
this is all just a thought etc and if it is a stupid one I hope some will tell me! 
 
Cheers 
Chris.
