[. . . ] 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 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. Description The RE90P-12 and RE90P-18 podium microphones are phantom-powered "backelectret" miniature condenser gooseneck microphones. The back-electret 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 shock-mounted (CPSM shock-mount kit) accessories are also available. The RE90P12 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 small-diameter 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 micro- RE90P-12 and RE90P-18 Condenser Cardioid Gooseneck Microphones Mounting Accessories CPSM SHOCK-MOUNT KIT nal balanced output, with an output level of ­43. 0 dB (0 dB = 1 mW/pascal). In addition, the Limited Warranty for the acoustic system contained in these microphones shall apply for the life of the product, defined as a period of ten (10) years from the date that the manufacture of the specific microphone has been discontinued. Any and all active electronics incorporated in these microphones are guaranteed against malfunction due to defects in materials or workmanship for a period of three (3) years from the date of original purchase. The Limited Warranty does not extend to cables, cable connectors, or switches. Additional details are included in the Uniform Limited Warranty statement.

RE90P-12 and RE90P-18 Condenser Cardioid Gooseneck Microphones 2 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 desk tops, 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.

Architects' and Engineers' Specifications RE90P-12 The microphone shall be a single-D cardioid back-electret condenser type with frequency response of 100 to 15, 000 Hz. The microphone shall have a 200-ohm nominal balanced output, with an output level of ­43. 0 dB (0 dB = 1 mW/pascal). [. . . ]
