At Fenway Park the PA announcer's booth provides one of the greatest possible
vantage points from which to observe the action; it's high up, just
to the right of home plate, on the 5th level (i.e. press level).
It's a two man booth; in addition to myself there's a sound engineer who
manages the sound "mixing board", and there are various
items of electronic equipment in the booth --
the two I personally utilize are the microphone
and the device which enables me to enter certain data on the left field scoreboard.
(In addition to doing the PA announcing, I also operate that part of
the left field scoreboard (at the base of the so-called "Green Monster")
which informs the people present:
At bat - uniform jersey number, balls, strikes, outs, hit or error - and who's
charged with the error on close call scoring decisions.)
The sound engineer ensures that the sound levels are correct for the various audio
which comes through the ballpark's speaker system - whether it be organ music, CD
music - from classical to marches to rock, or my voice. He must ensure
that my microphone is "live" for every announcement I have to make.
My sound engineer's name is Mike Wilkens; he's very capable.
He's been at Fenway Park in this capacity for two years.
