Capsule & Audio Performance

At the heart of the SM4 is a 1-inch brass dual-diaphragm capsule, engineered to consistently reproduce every element of a performance with remarkable accuracy and exceptional low-frequency control. The uniform cardioid polar pattern provides superior off-axis rejection of unwanted noise, and the large "sweet spot" reduces proximity effect, resulting in clean, controlled low-end and smooth, detailed highs.

Patent-Pending Interference Shielding Technology

One of the SM4's most distinctive features is its Patent-Pending Interference Shielding Technology, which blocks 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. This makes the SM4-K Kit especially well-suited for modern home studio environments where electronic interference is an ever-present concern.

Versatility, Durability & Complete Kit

The SM4 is 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 up to a maximum of 140dB. Rugged, all-metal construction and a sleek, low-profile design ensure the microphone won't obscure the performer or the environment, while its camera-ready aesthetic suits both audio and video production workflows. The SM4-K Kit includes the A4SM shock mount and A4PF detachable magnetic pop filter, which together with the internal pop filter create a two-stage filtering system that dramatically increases resistance to plosives for easier post-production work.

Why We Love This

Our gear experts appreciate the SM4-K Kit because it keeps them in the creative flow rather than chasing down audio problems. The dual-diaphragm capsule reproduces every element of a performance with remarkable accuracy, while the internal pop filter and interference shielding mean tracks arrive mix-ready. Whether recording delicate vocals or loud instruments, the SM4 works with any interface to achieve professional-quality results, no matter the environment.
