Hmm, right. And that means that the original poster (who undoubtedly has been waiting by his keyboard all this time without breaks for meals, changes of clothes, bathroom usage, job and/or relationship experiences, etc.) was probably talking about the original "BlueTube" preamp rather than the model they sell nowadays.
That was rather a piece of garbage, although it came in a neat little package. What I remember most of all was its "+48V" phantom powering switch, which actually delivered about 30 Volts at the microphone sockets (open circuit). And when I called the manufacturer to complain about this, they didn't have a clue as to why that might be a problem; they acted as if "48V" was a generic expression. Also, you couldn't turn the tube effect (deliberately added distortion) completely off.
I understand that the present-day version is better in both respects, though it's not in the neat little package any more. Whatever.
