Omni is omnidirectional, meaning it listens to the entire room. 
PlainTalk mics were unidirectional, meaning that they only listen to 
what is pointed directly in front of them.  This was necessary for 
ensuring the Mac would only listen to its user instead of background 
noise. The Q700 was years before PlainTalk, which debuted in the 
LC520 Edu and [Q|C]840/660AV (the 700 & 900 were the first Quadras).

Given its name, amplified...generally, when referring to audio 
outputs, it's either line-level, or it is speaker-level. It is likely 
just a different name for a headphone jack...they needed a different 
name for when they had a convenient jack in the front (headphone) as 
well as the jack in the rear (speaker).

It is a stereo mini jack with a stereo output signal for the speaker 
jack. The mic jack is a mono mic-level jack.
