HypercardioidWide CardioidShure KSM9HS

Multi-Pattern Condenser Microphone

The KSM9HS is a new premium stage vocal microphone, based on the design and success of the KSM9. While the KSM9 offered Cardioid and Supercardioid patterns, the KSM9HS offers Hypercardioid and Subcardioid (wide cardioid), selectable via a switch under the grille.

As does the KSM9, the HS employs a dual-diaphragm, prepolarized, 3/4-inch capsule (outside diameter 19.8mm, according to Shure). Electronic circuitry combines the output of these two diaphragms to produce the Hypercardioid or Wide Cardioid pattern.

The self-noise and sensitivity figures vary with pattern:

Hypercardioid2.98 mV/Pa20.7 dBA
Subcardioid2.23 mV/Pa22.7 dBA

The impedance circuitry is transformerless, and according to Shure is built with premium components and gold-plated connectors.

Live Sound International - 2013
[…] while many mics change tonality when you get off-axis, the KSM9HS sounds the same all around the pattern. Even cupping the capsule did not radically change the sound. I had several people at the shop check it out as well, and their input was unanimous that sound is remarkably even and doesn’t change no matter the positioning of the vocalist.

The mic ships with a clip and an aluminum carrying case.
