I just bought a blackstar ht-5 head and I also have 2 external cabs wich are both 8 ohms. My idea was to hook up both cabs, until I read this:
The output marked ‘1x16 Ohm’ is for the connection of a single 16 Ohm extension speaker cabinet (or the internal loudspeaker of the HT-5 combo). The outputs marked ‘1x8 Ohm or 2x16 Ohm’ are for the connection of either a single 8 Ohm extension cabinet or two 16 Ohm cabinets. Also, the internal loudspeaker of the HT-5 combo can be plugged in here if it is used with a 16 Ohm extension cabinet.
WARNING: The output marked ‘1x16 Ohm’ should never be used at the same time as either of the outputs marked ‘1x8 Ohm or 2x16 Ohm’.
maybe this picture will make things more clear:
so does anyone know a safe way to make it possible of hooking up both cabs?
