So I ordered one of these as I only had one of them lying around for some reason. Arrived in perfect timing, got to use it and my other one to daisy chain from my main speakers to a couple of smaller ones for a rehearsal session that was had at the studio. Made the P.A. look beastly. Very handy and will also prove useful in case of an emergency at live events where I'm having to use multiple sets of F.O.H. speakers that aren't mine. THANKS THOMANN ONCE AGAIN!!!
