Overview

The Peavey PM 18S Podium Microphone is purpose-built for spoken-word applications where vocal clarity and feedback resistance are paramount. Its back-electret condenser element paired with a cardioid polar pattern focuses pickup tightly on the speaker, rejecting sound from the sides and rear of the capsule. This makes it particularly effective in acoustically challenging environments like houses of worship, auditoriums, and conference venues where ambient noise and room reflections can compromise intelligibility. The specially tailored frequency response is voiced for the spoken word, ensuring natural, present vocal reproduction without the harshness or boominess that can plague general-purpose microphones repurposed for podium duty.

Weighing just 9.1 ounces with overall dimensions of 26.3 x 3 x 3 inches, the PM 18S offers enough gooseneck reach to accommodate speakers of varying heights while remaining unobtrusive at the podium. The wired corded electric design provides a reliable, interference-free signal path and eliminates battery management. With a 78 dB signal-to-noise ratio, the microphone maintains clean audio even during quieter speech. Available in both black and white finishes, the PM 18S integrates easily into professional presentation environments where appearance matters as much as audio quality.
