Shure MX418/S Microflex 18" Gooseneck Microphone Supercardioid...
Product Overview
The Shure MX418/S is an 18-inch supercardioid gooseneck microphone built for commercial AV installations that need tight pickup and strong off-axis rejection. With an attached preamp and balanced XLR output, this gooseneck microphone suits conference room integration, lecterns, and house of worship speech reinforcement in acoustically challenging rooms. The supercardioid cartridge narrows the pickup angle to isolate the talker and suppress nearby noise sources.
Product Description
The MX418/S pairs an 18-inch gooseneck with a supercardioid Microflex cartridge, as shown in the product image, delivering a narrower acceptance angle than a cardioid for higher gain-before-feedback in live speech reinforcement. Its balanced, transformerless preamp output maintains a clean signal across the long cable runs common in distributed commercial AV systems, and Shure CommShield technology rejects RF interference from nearby mobile devices. The microphone ships with a complete installation kit including a shock-mount and flange-mount adapter and a snap-fit foam windscreen for fast table and lectern installation. Because the cartridge is interchangeable, integrators can refit a cardioid or omnidirectional capsule as room acoustics change. For a wider pattern or longer reach, compare it with the Shure MX418/C cardioid and the Shure MX424/S 24-inch supercardioid.
Key Features
- Supercardioid Polar Pattern — The narrow acceptance angle isolates the talker and rejects off-axis noise for higher gain-before-feedback in live speech reinforcement.
- 18-Inch Gooseneck Reach — The mid-length gooseneck positions the capsule near a seated talker at a lectern or conference table.
- Attached Preamp with XLR Output — The integral balanced, transformerless preamp feeds standard XLR inputs and mixers in commercial AV racks.
- Interchangeable Microflex Cartridge — The capsule can be swapped to cardioid or omnidirectional as room coverage requirements change.
- CommShield RF Rejection — Built-in filtering suppresses interference from nearby smartphones and wireless devices.
- Complete Installation Kit — An included shock-mount and flange-mount adapter plus a snap-fit foam windscreen speed table and lectern installation.
