Shure MX418D/C – 18-Inch Gooseneck Condenser Microphone

The Shure MX418D/C is a professional-grade 18-inch gooseneck condenser microphone designed to deliver exceptional speech clarity in institutional and commercial AV environments. With a cardioid polar pattern, it ensures focused audio pickup while effectively reducing ambient noise. Consequently, presentations, lectures, and announcements are captured with unmatched precision, providing clear and intelligible sound for every audience member.


Featuring a wide frequency response of 50 Hz – 17 kHz, the MX418D/C captures both low and high-frequency details. This results in natural-sounding speech reproduction, while background noise is minimized. Moreover, the integrated desktop base includes a programmable on/off switch, logic I/O terminals for remote control, and a bright LED ring to indicate the microphone status, ensuring easy operation and visual feedback.


Designed with RF-resistant circuitry, the MX418D/C prevents radio-frequency interference in sensitive AV setups. Additionally, its shock-mounted base isolates the microphone from table vibrations and handling noise, enhancing overall sound quality. Therefore, it is ideal for applications where clear and uninterrupted speech is critical, such as podiums, lecterns, courtrooms, and houses of worship.


The microphone is shipped with a snap-fit windscreen to reduce plosives and breath noise effectively. In addition, a 10-foot XLR cable is included, allowing immediate plug-and-play integration into professional audio systems. Consequently, installation is straightforward, and minimal setup time is required, which is beneficial for both temporary and permanent AV installations.


Furthermore, the MX418D/C’s rugged construction ensures long-term reliability, even in high-traffic or professional environments. Its sleek design complements podiums and desktop surfaces while maintaining durability. Therefore, this microphone is not only highly functional but also visually unobtrusive, blending seamlessly into any professional AV setup.
