Electro-Voice RE90P-12, RE90P-18 Technical Specifications

Key Features:

• 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 allo ws long cable runs

• Optional CPSM podium shock mount
provides more than 15 dB of mechanical
shock isolation at 200 Hz

General Description:

The Electro-Voice® RE90P-12 and RE90P-18 podium
microphones are phantom-powered “back-electret”
miniature condenser gooseneck microphones. The back­electret feature provides greater sensitivity, wider frequency
response, and superior immunity from handling noise than
a diaphragm-electret microphone. 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 shock­mounted (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 reproduction with natural
sound pick-up optimized for close-up use. The small­diameter gooseneck has two supple joints and a rigid center
tube. The rigid tube prevents unsightly twisting of the
gooseneck but permits the user to exactly position the
microphone. The electronics housing has a 3/4 - inch
diameter base terminated with an XLR-type 3-pin connector
which allows the microphone to be plugged directly into an
existing panel-mount XLR-type receptacle. 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 performance. The RE90P-12 and
RE90P-18 are designed to be phantom powered with a
wide voltage range, 9-52 V dc (DIN Standard 45 596).

Application Notes:

The RE90P-12 and RE90P-18 gooseneck microphones are
designed for sound reinforcement applications requiring high
quality, wide response and a uniform polar pattern in a slender,
adjustable gooseneck microphone. The RE90P-12 and RE90P­18 can be employed on lecterns, podiums, and on mixing consoles
as a talk-back microphone or other applications which require a
quick plug-in gooseneck microphone. Applications of close or
normal miking of speech at podiums, lecterns or pulpits normally
require a windscreen to control breath noise and P-popping or, in
some cases, wind noise from circulating air. A small two-stage
foam windscreen is included with the RE90P-12 and RE90P-18
mics. This two-stage filtering provides greater isolation from P­pop noise in a smaller package. In some locations, there is a
desire to permanently 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 t ape 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 reception. Next remove the
protective front layer of the attached tape. Now , pull the windscreen
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.

Mounting Accessories:

CPSM Shock-Mount Kit

The Electro-Voice CPSM shock mount effectively isolates the
mounted RE90P-12 and RE90P-18 podium microphones from
shock-induced vibrations that would be experienced on podiums,
pulpits, table and desktops, plus it provides theft-resistant security.
Compared to hard mounting, the CPSM shock mount provides
15 dB (over 5 times) of shock isolation at 200 Hz.

FMK Flange-Mount Kit

For installations which do not require a shock mount, the FMK
flange mount is designed for quick installation on podiums, pulpits,
table and desk tops, and provides theft-resistant security.
