Microphones never EVER have a characteristic that defines the distance
at which they will record a sound. They instead have a sensitivity to
the pressure level of the sounds that reach them. Whether a person speaking
at a distance of 20 feet will be adequately recorded while the mic/recorder
is in a pocket depends on the sound pressure level that reaches the mic and
the sensitivity of the mic and the gain of its amplifier.

I believe that the thing that makes people believe that mics have a "range"
characteristic is that microphones can be constructed to be directional.
That is, they can reject sounds that arrive from their side or back while
not rejecting sounds that arrive from their front. This makes them appear
to reach out to sounds from the front, but this isn't really the case.
Instead, it allows one to increase the mic's amplifer gain to increase
the level of desired sounds without increasing the level of undesired
sounds.

I'm not familiar with this unit, but I suspect that the built-in mics on
any of its kind are best suited for dictaphone-type work.

1981 was a long time ago, but Romero's _Knightriders_ seemed
important at the time and sunk without a trace. Ed Harris as
a charismatic touring troupe leader trying to maintain an
impossible ideal. Very 1981 if you're geezery enough to dig
postwar vibe. DVD rumoured for this summer.
