Description
The RE90P-12 and RE90P-18 podium mi-
crophones are phantom-powered “back-
electret” miniature condenser gooseneck mi-
crophones. The back-electret feature pro-
vides greater sensitivity, wider frequency re-
sponse, and superior immunity from han-
dling noise than a diaphragm-electret mi-
crophone. The RE90P-12 and RE90P-18 are
mechanically designed for quick, easy
mounting to a lectern, pulpit or podium
equipped with a bulkhead female XLR-type
3-pin receptacle. For permanent installation,
optional fixed (FMK flange-mount kit) and
shock-mounted (CPSM shock-mount kit)
accessories are also available. The RE90P-
12 and RE90P-18 are designed for sound
reinforcement applications. The frequency
response is tailored for full-range sound re-
production with natural sound pick-up op-
timized for close-up use. The small-diam-
eter gooseneck has two supple joints and a
rigid center tube. The rigid tube prevents
unsightly twisting of the gooseneck but per-
mits the user to exactly position the micro-
phone. The electronics housing has a
3
/
4
-inch
diameter base terminated with an XLR-type
3-pin connector which allows the micro-
phone to be plugged directly into an ex-
isting panel-mount XLR-type recep-
tacle. The housing is machined steel for
ruggedness and superior EMI/RFI attenua-
tion. The electronics’ output circuit utilizes
a transformerless balanced construction with
a low-output impedance, which is typically
200 ohms. This permits very long cable runs
without degrading the microphone perfor-
mance. The RE90P-12 and RE90P-18 are
designed to be phantom powered with a
wide voltage range, 9-52 V dc (DIN Stan-
dard 45 596).
Applications
The RE90P-12 and RE90P-18 gooseneck
microphones are designed for sound rein-
forcement applications requiring high qual-
ity, wide response and a uniform polar pat-
tern in a slender, adjustable gooseneck mi-
crophone. The RE90P-12 and RE90P-18
can be employed on lecterns, podiums, and
on mixing consoles as a talk-back micro-
phone or other applications which require a
quick plug-in gooseneck microphone.
Applications of close or normal miking of
speech at podiums, lecterns or pulpits nor-
mally require a windscreen to control breath
noise and P-popping or, in some cases, wind
noise from circulating air. A small foam
windscreen is included with the RE90P-12
and RE90P-18 mics. This windscreen is
made of two stages of foam (a dense exte-
rior surrounding a sparser core) which is
easily slipped over the transducer. This two-
stage filtering provides greater isolation
from P-pop noise in a smaller package.
In some locations, there is a desire to per-
manently attach the foam windscreen to the
microphone to prevent loss. Included with
the microphone are two strips of double-
sided tape (the second strip is a spare). To
permanently attach the foam windscreen,
first crack and peel off the protective back
layer of one strip of tape. Apply the tape to
the transducer by wrapping it around the
gooseneck adapter. The eight screened ports
on the transducer should be well above the
tape so as to not disturb the sound recep-
tion. Next remove the protective front layer
of the attached tape. Now, pull the wind-
screen down over the tape, stopping when
the end of the foam is even with the flexible
gooseneck. Caution: the windscreen foam
is delicate and therefore easily ripped by
applying too much force.

Condenser Cardioid
Gooseneck Microphones
• Small size – unobtrusive for podium
applications
• Frequency and cardioid polar response
uniform across the range, for natural
sound and high resistance to feedback
• All-metal construction substantially
reduces noise from stray magnetic
fields and RFI
• Low, 200-ohm output allows long
cable runs
• Optional CPSM podium shock mount
provides more than 15 dB of mechnical
shock isolation at 200 Hz
