Hi,

I just bought a Origin 50H head as a spare for my DSL 100hr while it is in the shop. The problem I'm having is I can only plug one speaker cab at a time, one is a 16 ohm cab with 4 12's, the other is a 8 ohm with 2 12 inch V30's. when they are both pluged in only the 8ohm 2 12's work, if I unplug the 2 12 cab then the 4 12's work. Is this normal or should I return it?

Thanks for your time.
