Hey guys, I was having trouble understanding the difference between AB boxes, ABY boxes, and Combiners. For example the Morley AB/ABY Box. The Morley has an A and B jack and an In/Out. Is it an AB box or an ABY? I’ve seen it marketed as both. Is it essentially the same thing? And as for Combiners, aren’t they the same as AB/ABY boxes? You can either combine or split the signal? Thanks!
