shelve down at and below the frequency F,
where F= 750/D, and D = the boundary dimen-
sion in feet. At approximately F= 188/D, the
output of the microphone is down 6 dB, be-
comes omnidirectional, and maintains a flat

If your mixer or recorder requires an unbalanced
phone plug connector, modify the cable exiting
the power supply as follows: solder the cable
shield and the pin-3 lead to the phone-plug
ground terminal. Solder the pin-2 lead to the
phone plug “hot” or “tip” terminal.
Placement
PZMs are designed to operate on any stiff, non-
absorbent boundary (or surface). Typical bound-
aries are a floor, wall, ceiling or table. This type
of mounting maintains the flattest low-frequency
response.
The published response curve is measured on
an “infinite” boundary such as a floor, ceiling or
wall. The microphone’s low-frequency response
depends on the size of the boundary on which it
on an infinite boundary. The element shall be
a sub-miniature electret type of rugged
construction.
A smooth frequency response from 20 Hz to
20 kHz shall be obtained. The response shall
be switch-selectable between flat (F) or
rising (R).
The microphone shall employ the patented
PRP principle for maintaining phase coher-
ency, thus eliminating comb filtering in the
audible spectrum.
Permanently attached to the microphone is a
fifteen-foot black cable with an XLRM con-
nector.
The PZM6 D shall have a sensitivity of
–43 dBV/Pa. The microphone shall accept
150 dB SPL input while contributing no
greater than 3% THD (open circuit
termination). Equivalent noise shall be
typically 20 dBA re .0002 dyne/cm

Service
If the microphone does not function properly,
check that it is placed correctly and is con
nected as described in the Operating Instruc-
tions. Also check mic cables and your power
supply. If you determine that the
microphone product is defective, return
the complete product in its original
packaging to one of the addresses below .
