RECORDING / BROADCAST
CM-700, CM-700MP
Professional Recording
The CM-700 is a cardioid condenser microphone for use in
professional recording and sound reinforcement. It repro-
duces music with an accurate, natural sound. Handling up to
151 dB SPL before overload, this mic is an excellent choice
for miking overhead drums or acoustic instruments. The CM-
700 also features a 3-position roll-off switch. A stereo
matched pair of CM-700s is available as the CM-700MP.
Element Type: Electret Condenser
Frequency Response: 30 Hz to 20 kHz
Polar Pattern: Cardioid
Impedance: 190 ohms
Sensitivity: 2.5 mV/Pa
PZM-30D
Rugged Pressure Zone Microphone
Clear, natural sound without phase interference
from surface sound reflections. Excellent
“reach.” Uniform polar response. The PZM-30D
offers all of these PZM advantages. A switch-
able dual-frequency response provides a “ris-
ing” position that adds brilliance and articula-
tion, while the “flat” position maintains a
smooth, flat and natural high-frequency
response. Miniaturized electronics allow direct
connection to a mixer with phantom power. The
mic accepts a rugged detachable cable.
Element Type: Electret Condenser
Frequency Response: 20 Hz to 20 kHz
Polar Pattern: Hemispherical
Impedance: 240 ohms
Sensitivity: 7 mV/Pa
PZM-6D
Inconspicuous, Lightweight PZM
A smaller plate makes the PZM-6D even more inconspicuous
than the PZM-30D, while performance remains the same.
Mounts easily on panels for overhead stereo miking, or on
the underside of a piano lid. The microphone offers switch-
able “rising” response for bright sound or “flat” response for
natural sound. Miniaturized electronics in the XLR-type con-
nector housing are attached to the mic via a 12-ft. mini cable.
Element Type: Electret Condenser
Frequency Response: 20 Hz to 20 kHz
Polar Pattern: Hemispherical
Impedance: 240 ohms
Sensitivity: 7 mV/Pa
MIC TIPS
Studio Recording: Microphone
Choice and Placement
Several suggestions for mic techniques
used in studio recording can be found in
the Crown Microphone Application Guide
for S tudio Recording at
www.crownaudio.com. Under Expert
Advice, Mics, click on Tech Info.
Here is an example of a suggested mic
technique:
Grand Piano
• Raise the lid. Tape a GLM-100, PZM-6D
or PZM-30D to the underside of the lid in
the middle. For stereo, use two over the
bass and treble strings. If you need more
isolation, close the lid. Cut a few dB at 300
Hz to reduce boominess.
• Raise or remove the lid. Place two
CM-700s, CM-150s, or GLM-100s 8 to 12
inches over the bass and treble strings, 8
inches horizontally from the hammers. If
desired, boost a few dB at 10 kHz for
clarity.
• Remove the lid. Place two GLM-100s or
CM150s about 12 inches apart, angled 90
degrees apart, 18 inches over the sound-
board and 10 inches horizontally from the
hammers. If desired, boost a few dB at 10
kHz for clarity.
