No phantom on 5&6, just gain from non-Kashmir preamps,
I think the confusion here is the definition of "preamp." I think there is a ~60db gain range on these inputs, and it wouldn't surprise me at all if you could run a phantom box into these inputs for loud rock concerts without a "preamp."
Kashmir is simply a
marketing term for these particular kind of combo jacks which take 1/4 inch or xlr, "line" or "mic" and provide 12v or 48v phantom power.
Channels 5 & 6, on the mini jack are
designed for "line" and not "microphone" level inputs. Hence no phantom. Makes running 2 pairs of microphones and a SBD feed (might need attenuator cables coming from XLR "pro" outputs on the SBD to prevent "brickwalling"), or an outboard stereo preamp easy. (Though input volume control is via the [tiny] headphone knob).
I'm happy that SD
didn't add two more preamps to the mixpre6- it would have raised the cost to over a grand- an $899 box is going to have compromises. But with the (relatively inexpensive) addition of a 1/8 inch input, they gave me two more channels. It's also fun to use a single stereo preamp for fun and "flavor" in those "extra" channels.
