Shure MX418SE/S
18" Supercardioid Gooseneck Microphone with Switch


The Shure MX418SE/S 18" Gooseneck Condenser Supercardioid Microphone comes with an attached XLR Preamp, Shock & Flange Mount, 10' Side- (or Bottom-) Exit Cable, Snap-Fit Foam Windscreen.

MX400SE Series microphones are miniature gooseneck-mounted electret condenser microphones designed primarily for speech and vocal pickup. Their high sensitivity and broad frequency range make them suitable for recording, as well as sound reinforcement

The MX400SE series can be screwed onto a mic stand or the supplied 5/8 in. 27-threaded flange. They can be easily changed from side exit to bottom exit to conceal the cabling. All models include an in-line preamplifier, and a 3.66 m (12 ft.) cable.

NOTE: Actual product may vary slightly from picture shown.
