Subway station
Mount PZMs of your choice in posts, in the ceiling,
or in walls.
Mount the mics 10 feet above the floor, out of reach
(Fig. 5).
Figure 5
If the mics will be 10 feet from people on the aver-
age, mount the mics 20 feet apart to pick up everyone
about equally. That is, the mics should be no more
than twice as far apart as they are from the people.
Entry
Mount a PZM in an overhang, or mount an MB-3
aiming down over the entry (Fig. 6). It is best not to
expose the microphone to rainfall.

GLM-100 techniques
The GLM-100 miniature mic is easy to install and is
for temporary use. Simply tape it to a wall, ceiling,
or upper corner of a room.
If possible, place the GLM so it has a line of sight to
the person speaking. A mic behind a barrier or fabric
tends to sound muffled.
By following the suggestions in this guide, you
should be able to discreetly pick up speech and other
sounds with clarity.
