Overview
The Shure MX418D/C is an 18-inch Microflex gooseneck microphone with a cardioid electret-condenser cartridge and integrated desktop base. It is designed for speech applications including lecterns, podiums, conference rooms, courtrooms, and other presentation environments.
Microphone Performance
The cardioid pickup pattern provides a 130-degree pickup angle and is designed to capture speech from the intended sound source while reducing pickup from off-axis directions. The microphone has a 50 Hz to 17 kHz frequency response, 123 dB maximum SPL, 65 dB signal-to-noise ratio, and 94 dB dynamic range.
Desktop Base and Controls
The integrated desktop base provides a stable mounting platform and includes a programmable mute switch with LED indication. The switch can be configured for momentary or toggle operation using the base controls. Logic input and output connections support remote control or use with automatic microphone mixers.
Connectivity and Power
The microphone uses a balanced three-pin male XLR output through its attached 3 m cable. It requires 11–52 VDC phantom power at 2.0 mA. The balanced transformerless output is designed to provide resistance to electromagnetic interference during longer cable runs.
Cartridge
The MX418D/C is supplied with the cardioid R185 cartridge. Microflex cartridges are interchangeable, allowing compatible cartridges with different pickup patterns to be used when the installation requires an alternative directional characteristic.
Key Features
- 18-inch flexible gooseneck microphone with cardioid pickup pattern
- Electret-condenser transducer with 50 Hz to 17 kHz frequency response
- Integrated desktop base with programmable mute switch and LED indicator
- Attached 3 m cable with balanced three-pin male XLR connector

Applications
The MX418D/C is suited to lecterns, podiums, conference tables, courtrooms, houses of worship, presentation spaces, and other speech-focused sound reinforcement installations.
DC Supplies Product Note
The MX418D/C specifically combines the 18-inch MX418 gooseneck with an integrated desktop base. The D/C configuration should not be confused with MX418/C, which uses a separate mounting arrangement rather than the integrated desktop base.
