SHURE / KSM40C-J

Released August 2026. KSM40C's precision 1-inch capsule provides rich lows and detailed highs with warm, natural sound. Consistent cardioid response and smooth proximity effect suit varied sources. Includes shock mount, pop filter, case, hard mount, spare bands and thread adapter.

Features
■ Rich lows and natural detail from a 1-inch capsule
The precision-engineered 1-inch capsule reproduces smooth high-frequency detail without excessive brightness or harshness. A proprietary backplate controls diaphragm movement to suppress sharp resonances.

■ Consistent cardioid pickup for easy placement
Focused pickup minimizes ambient sound and bleed, making positioning quick in multimiked sessions or imperfect rooms. Smooth proximity effect offers creative control: closer positioning gives a stronger sound, while greater distance produces a more neutral tone.

■ Extremely low self-noise
Very low self-noise supports clean recordings of quiet passages, allowing gain and compression with minimal audible hiss.

■ Modern design with high-quality materials
The aluminum body balances durability with low weight for easy boom mounting. A precision-machined steel grille complements the gold-layer capsule.

■ Shock mount, pop filter and accessories
The included shock mount and removable pop filter reduce low-frequency noise, vibrations and plosives. A premium case stores the microphone with its shock mount fitted. A thread adapter and eight replacement suspension bands are also included.
