Thank you. That's all I asked. I have several dozen inputs and outputs
that can handle +22dBu -- it's a typical maximum output for audio equipment.

I wasn't whining. I was merely asking a specific question in response to
what seems to be contradictory information. I received answers that lead
me to me to believe that a 410 built to be used with the rest of the system
(which is what anyone would want in a modular) might have needed a special
high-voltage pre-amp in order to be able to process external signals.
Apparently, that isn't true.
Yes, I realize that motm has a published specification of 10V p-p. Yet,
everything else I own is specified in dBu. Even after trying to look it up
in several books, I did not feel confident in trying to calculate one value
from the other. So I asked the list for a better answer.

Yes, I can see that, but I'm not planning on buying a 440 or a 420. Nor
does it tell me anything about their output levels. Regardless, I am
planning on buying several other modules that have audio inputs and audio
outputs. If the levels of the motm were as high as some people were
saying, then I wouldn't be able to use either the inputs or the outputs
with the rest of my equipment. Luckily, these people were wrong. Thank
you for clarifying such an important issue.
I'm no engineering genius, but come Monday morning, I know I could call
every manufacture in the Mix directory from api to Z-Systems, ask them the
maximum input and output levels of something they make, and as ignorant or
unnecessary as that might seem, not once will any of them SHOUT AT ME,
accuse me of ranting, or call me a whiner. In the world of audio, where
are things are made to be connected to each other, it's considered a fairly
basic question.
So I apologize if I overreacted or offended anyone in any way.
