It's so loud at NAB that sound is pointless, plus when this plays in dealer showrooms they usually have the sound off as well.

MOS for those that aren't familiar with this:

The term "MOS" is used, on a slate, when a scene is filmed without sync sound (or any sound).
What MOS orginally stood for is still up for discussion.

The "Mit out Sound" legend
Some of the early directors in Hollywood, whose first language was German, had trouble with the sound with. So instead of saying, " we are recording this scene "without sound" the words came out "We are recording this scene mitout sound. Because this word corruption, MOS means "without sound"

wow, if only my production company would spring for nice equipment like that!

Yo tengo la ex1 pero la ex3 es ok ok

Very Cool! Digging what you guys do for shooters!
Hey maybe , i'll make it on there!

Well actually, mit out sound, would mean "with out-sound" and not "without sound". This makes sense as someone who doesn't speak English well, would think that "out-sound" is a word, and he would say record "with" "out-sound", just like you would say record "with sync sound" for example.
