Smooth and Natural Audio Reproduction 
Equipped with a brass 1-inch dual-diaphragm capsule, the SM4 captures clean, controlled low-end and smooth, detailed highs. The uniform cardioid polar pattern provides superior off-axis rejection of unwanted noise, and the large “sweet spot” reduces proximity effect.  
 
Patent-Pending Interference Shielding Technology 
Block unwanted RF noise from common wireless devices including cell phones, laptops, and wi-fi routers. The proprietary system features an integrated pop-filter and woven mesh faraday cage that shields the microphone capsule for clean audio capture.   
   
Mix-Ready Sound, Effortlessly   
Internal pop filter enables clean, plosive and rumble-free recordings for easier post-production work. Compress or EQ to taste without bringing forward unwanted elements that can plague recordings and mixes.  Additionally, the SM4 works with any interface to achieve professional-quality recordings, no matter the environment. 
  
Exceptional Flexibility for Vocal and Instrument Recording  
Optimized to capture a wide range of sound sources from soft vocals to loud instruments including drums, guitar amps, and horns with exceptionally high-SPL handling (max SPL of 140dB). 
 
Legendary Durability & Camera-Ready Design 
Rugged, all-metal construction and exceptionally high-SPL handling from a brand with decades of experience in producing reliable gear for the stage and studio.  A sleek, low-profile design won’t obscure the performer or environment.  

Shock Mount & Detachable Magnetic, Pop Filter
Included with the SM4 Home Recording Kit and available separately, the shock mount and detachable pop filter dampen undesired noises including rumbles, vibrations and plosive “pop” sounds. When combined with the internal pop filter of the microphone, the detachable pop filter creates a two-stage filtering system that dramatically increases the resistance of plosives.
