Large Dual-Diaphragm Vocal Microphone

Premium cardioid condenser microphone with capsule ideal for world-class vocal recording.

 

Dual-diaphragm cardioid microphone delivers exceptionally smooth proximity control and ultra-wide dynamic range. It features a natural off-axis response, a dual-diaphragm with a gold Mylar diaphragm, 3-stage grille, and internal shock mount.

 

  • Highly consistent cardioid polar pattern creates a broad “sweet spot” and natural off-axis response
  • Prethos® Advanced Preamplifier Technology exhibits extremely low self-noise with superior dynamic range, transient response and ultra-low distortion for transparent recording
  • Dual-diaphragm design with an active front, ultra thin (2.5 micron) 24-karat gold, low mass, 1-inch Mylar® diaphragm
  • Passive back diaphragm delivers exceptional control of low frequency proximity effect
  • Tailored low-frequency roll-off minimizes low frequency room noise
  • Integrated three-stage mesh grille guards against wind and breath noise
  • Open cage ShureLock® rubber suspension shock mount with low-profile Popper Stopper™  magnetic pop filter produces a natural space between performer and microphone
  • Extremely low self noise for critical studio vocal recording
  • Premium electronic components and gold-plated internal and external connectors
  • Durable zinc die-cast housing and hardened low carbon steel grille
  • Internal shock mount to reduce unwanted handling and stand noise
