Crown PZM-10 Application Manual page 9

The wedge can be suspended, or can be placed on edge
on the floor, with the PZMs at the junction of the floor
and the vertical panels (as in Fig. 11).

• Place two panel-mounted PZMs about 3 to 12 feet
apart, 14 feet high, and 5 to 20 feet from the first row
of players. Place the microphones farther apart to
widen the stereo spread, closer together to narrow
the spread.
• For noncritical documentary recordings, PZMs can
be taped to the proscenium arch, the backstage wall,
or the floor in front of the ensemble.
Choirs:
• Try two PZMs on panels, 5 feet above and 3 to 15 feet
in front of the choir. Coverage is wide and the re-
sponse is uncolored off-axis.
• For small choirs singing in an open area, place PZMs
or PCCs on the floor in front of the group.
• For choirs seated on one side of a church chancel or
small chapel facing the other side of the chancel or
chapel, mount a PZM on the wall opposite the choir.
Ambience:
• One or two PZMs on the walls give an uncolored
sound.
• One or two PZMs on the walls of an echo chamber
provide ambient richness and naturalness.
Audience:
• On panels suspended over left and right sides of audi-
ence.
• Two PZMs on the front face of the stage about 4 feet
apart.
Altars:
• Place a PZM or PCC on the altar table (perhaps under
the table cloth).
Recording a conference:
Note: These suggestions are for recording, not for
teleconferencing sound reinforcement. For teleconfer-
encing sound reinforcement applications, see the Crown
Microphone Application Guide for Teleconferencing
and Distance Learning.
For maximum clarity, hold the conference in an acousti-
cally "dead" room with carpeting, drapes, and acoustic-
tile ceiling.
• Lay a single PZM in the middle of the table (Fig. 12).
• On a long table, use one PZM in the middle of every
4 to 6 people. No person should be more than 3 feet
from the nearest microphone.
• For permanent installations, use the PZM-20R, a
recessed microphone with all electronics and cabling
under the table. Before installing it, first check that the
pickup will be adequate by testing a regular PZM lying
on the table.
• Try a PCC-170, a PCC-130 or a Mini Boundary mic
at arm's length for every one or two people.
• For more clarity, feed the PCCs into an automatic
mixer.
• If table placement is undesirable, try mounting a PZM
on the ceiling.
• Remove the plate from a PZM-6D. Install the capsule/
holder in an upper corner of the room as in Fig. 13.
This arrangement increases microphone output by
12 dB and gives surprisingly clear reproduction. Large
rooms may require such a pickup in all four corners.
