Electro-Voice re90p eds User Manual

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).

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
