Overview

The Shure MX412D/S is a supercardioid condenser microphone mounted on a 12" gooseneck with a dedicated desktop base — purpose-built for environments where intelligibility and consistency matter more than sonic character: conference rooms, broadcast desks, houses of worship, courtrooms, and lecture halls. The supercardioid capsule provides a focused pickup window aimed directly at the speaker's mouth, with strong side rejection that keeps neighboring voices, projector fans, and HVAC noise from bleeding into the channel. The wide dynamic range and extended frequency response capture speech with accurate transient detail — consonants register cleanly without proximity-effect bloom, and the transformerless balanced output keeps the noise floor low across the full cable run to the mixer or DSP.

Build quality reflects Shure's professional touring and installation standard: the gooseneck holds position without creep, the locking flange mount secures the base permanently to a table or lectern surface, and the snap-fit foam windscreen handles breath pops without adding mechanical bulk. The programmable switch and redesigned high-brightness LED deliver clear on/off status even under strong theatrical or conference lighting — a small detail that matters significantly in live-to-camera scenarios where a hot mic indicator needs to read from across a table. The logic I/O terminals connect directly to automatic microphone mixers or room control systems, allowing the base to function as an addressable node in a larger installed AV system rather than a standalone input. For integrators, that interoperability is what separates this from a generic gooseneck solution.

Pros & Cons

👍 Pros

  • Supercardioid pattern delivers tight, focused pickup that rejects side noise from adjacent speakers and room ambience.
  • Balanced transformerless output provides clean signal integrity across the included 10' cable run with strong resistance to RF and electromagnetic interference.
  • Programmable switch and high-visibility LED give speakers and moderators immediate, reliable visual confirmation of mic status under bright stage or conference lighting.
  • Integrated 20 dB shock mount isolation eliminates surface vibration noise without any additional hardware.
  • Logic I/O terminals enable seamless integration with automatic mixing systems for multi-mic conference and broadcast environments.

👎 Cons

  • The supercardioid polar pattern requires precise placement — speakers who lean significantly off-axis will hear a noticeable drop in presence and intelligibility.
  • No built-in pad switch means high-SPL close-talking sources can risk overloading the capsule, though this is rarely a concern in the speech-oriented applications this mic targets.
  • The 12" gooseneck length may feel constrained at larger lecterns or standing-height podiums where a longer reach is needed to position the capsule correctly.
  • Desktop base footprint is fixed — permanent installation via the locking flange mount is straightforward, but repositioning a semi-permanent setup takes more effort than a simple stand-mount mic.

Frequently Asked Questions

Yes, this is a condenser microphone and requires 48V phantom power. Most modern mixers, audio interfaces, and automatic microphone mixers supply phantom power natively — confirm your device has it enabled on the relevant channel before use. Without phantom power, the capsule will not produce audio signal.
Supercardioid is tighter than a standard cardioid, with a narrower pickup cone aimed directly at the speaker and greater rejection at the sides. This means you get stronger off-axis rejection of room noise and neighboring speakers, at the cost of a small rear lobe — position the base so the rear null isn't aimed at another open microphone or a loudspeaker.
Logic terminals allow the MX412D/S to interface with automatic microphone mixers (like Shure SCM series) or room control systems for remote muting, LED status control, and conference automation. If you're running a standalone setup into a standard mixer, you can simply ignore these terminals — they don't affect the audio signal path.
Yes. The Microflex MX400 series uses interchangeable cartridges. The MX412D/S ships with the supercardioid (D) cartridge installed, but you can swap to omnidirectional or cardioid capsules depending on application. This makes the base a long-term investment across different room configurations.
The integrated shock mount provides over 20 dB of isolation from surface-conducted vibration — keyboard typing, table thumps, and HVAC rumble transmitted through a desk surface are attenuated before they reach the capsule. In practice, this keeps low-frequency noise out of the signal chain without requiring a separate decoupling solution.
