Hi folks,
Just checking my understanding of this, the outputs of the 9.2 are parallel so whichever speakon output I use for a single cab will get either of the channels through them (if I wanted to switch from the FET to the Tube and vice versa).
However on the 12.2 version the outputs are per amp, one for amp a and one for amp b. So if I only have one cab and use the amp a output I won't get any sound if I wanted to switch to the other channel. If I did I'd need to use two cabs. Even further to this each channel would come out of the separate cabs, so each time I used one channel on it's own I'd only be using one cab. Bit of a bummer if your cabs are different sizes with therefore different characteristics. Also the only way to get the most power would be to mix the channels limiting your sound options!
Hopefully I misunderstand this!
