SHURE MX412 Gooseneck Microphones
General Description
The Shure Microflex MX412, MX418, and MX424 microphones are miniature gooseneck-mounted electret condenser microphones designed primarily for speech and vocal pickup. They can be mounted on lecterns, pulpits, or conference tables. All models include a preamplifier and are available with interchangeable cartridges.
- Wide dynamic range and frequency response for accurate sound reproduction
- Interchangeable cartridges that provide an optimal polar pattern choice for each application
- Shock mount provides over 20 dB of isolation from surface vibration noise
- A snap-fit foam windscreen reduces breath noise or plosives CommShield RF filtering reduces interference from nearby mobile devices
These microphones are available with 12 inch, 18 inch, or 24 inch goosenecks. Some models are also available with a built-in mute switch.
- “S” models include a mute button and LED.
- “D” models include a desktop base with a programmable mute button and LED and logic input and output.
- “SE” models feature a surface mount flange with a side-exit cable.
The polar pattern of the included cartridge is indicated by a model number suffix:
- /C Cardioid
- /S Supercardioid
- /MS Mini-shotgun
- /O Omnidirectional
- /N Cartridge not included
Interchangeable Cartridges
Microflex microphones use interchangeable cartridges that allow you to choose the polar pattern for different installations.
Snap-Fit Windscreen
- Snap into the groove below the cartridge.
- To remove, spread the gap with a screwdriver or thumbnail.
- Provides 30 dB of “pop” protection.
Preamp Gain
If necessary, the preamplifier gain can be reduced by 12 dB. Contact an
authorized Shure service center for information.
Microphone Placement
- Aim the microphone toward the desired source, such as the talker.
- Aim it away from any unwanted source, such as a loudspeaker.
- Place the tip of the microphone within 15 to 30 cm (6 to 12 inches) of the desired sound source.
- Always use the supplied windscreen or optional metal windscreen to control breath noise.
- If four or more microphones will be open at the same time, use of an automatic mixer is recommended.
Permanent Installation
Mount the microphone using one of the following methods.
Flange
- Drill a 22 mm (7/8 in.) diameter hole in the desired location.
- Trace and drill three starter holes for the supplied screws using the flange as a template.
- Insert the preamplifier through the mounting flange.
- Slip the mounting flange retaining ring over the bottom of the preamplifier and slide it up until it is flush to the bottom of the flange. Then press the ring firmly into place.
- Secure the flange to the mounting surface with three screws.
Shock Mount
- Drill a 44 mm (1-3/4 in.) diameter hole in the desired mounting surface.
- Mark and drill starter holes for screws, using shock mount as a template.
- Secure shock mount to the mounting surface with screws.
- Thread the supplied adapter onto the microphone before inserting it into the shock mount.
