Cardioid dynamic vocal microphone is the first high-end dual-diaphragm dynamic microphone. It features a patented Dualdyne cartridge to combat proximity effect and master off-axis rejection, and a patent-pending Diaphragm Stabilization System.

  • Patented cartridge design featuring two ultra-thin diaphragms (one active and one passive) and groundbreaking inverted airflow system, which allows exceptional consistency of the cardioid polar pattern throughout the entire frequency range.
  • Accurate frequency response due to controlled proximity effect which allows for neutral mid-and-high frequency reproduction, resulting in the most natural sounding dynamic microphone available.
  • Exceptional control of proximity effect vastly increases working distance without on-axis coloration.
  • Off-axis attenuation is flat and broad resulting in superior quality of rejection of unwanted sound sources for increased vocal clarity.
  • The Dualdyne cartridge re-images the Shure Pumping Pneumatic Shock Mount design with specific resistances and precisely machined components that are fully integrated into the cartridge’s acoustic properties.
  • Patent Pending Diaphragm Stabilisation System (DSS) Technology protects and stabilizes the active diaphragm from unwanted excursion or rocking during plosives or impact, providing substantial protection against high frequency handling noise.
  • Cutting-edge cartridge manufacturing methods utilise ultra-sonic and internal laser welding to provide best-in-class mechanical reliability.
  • Neodymium magnet resides in a micro-injection mold of aerospace SoftMag material that maximises the magnetic field for maximum output level.
  • Dent-resistant, hardened carbon-steel grille design lined with hydrophobic woven fabric provides exceptional plosive and wind protection, while offering virtually waterproof protection.
  • Aluminium handle with brushed nickel or black finish

Gordon Mack FOH Engineer for Jennifer Lopez

The KSM8 is a very full-throated mic. It captures all the warmth and depth of Jennifer's vocal without losing the crispness of a lightly sung lyric, all the while maintaining its composure as she struts in front of the PA. The only feedback I’ve had isn’t from the mic – it’s from people talking about the mic!

Michael Abbott Broadcast Mixer The Voice, Shark Tank

The off-axis rejection is amazing. Low-frequency response is very smooth, and high-frequency response is noticeably enhanced. I definitely noticed nice proximity control, too. It’s an exceptionally well-designed microphone by Shure.

Kevin Harvey The Smith Center Las Vegas, Nevada

The first thing I noticed about the KSM8 was how nice it looked; however, its good looks were very soon eclipsed by how great it sounded. The highs sounded silky and transparent with an equally impressive and very tight low-end response. Proximity effect is greatly reduced, leading me to bypass my compressor for the entire show. This is an excellent microphone and will be my first choice in vocal mic selection going forward.

Jason Batuyong Monitor Engineer iHeartRadio Stage

The KSM8 is a phenomenal mic for IEMs. It’s the only mic I can use with in-ears that sounds natural in the low end. It’s crazy how little processing and EQ it needs. The off-axis bleed is so clean that it immediately cleared up my in-ear mix.

J. Mark King Music/Production Mixer Dancing with the Stars, Country Music Awards

Warm and natural! I barely used any EQ or processing, which is every engineer’s dream! I think you have a real winner here. The KSM8’s versatility sets it apart.

Harold Blumberg Event Sound Designer

The KSM8 is stellar. I can say unequivocally that the KSM8 surpasses every other dynamic vocal mic I’ve tried. The polar pattern, proximity control, and flat top-end response give this mic a very wide and deep sweet spot that’s perfect for corporate events.

Brian Foisy & Mark Deadman Monitor & FOH Engineers Al Jarreau

Al’s mic technique is as varied as his vocal stylings, which range from beatboxing and vocal percussion to quiet whispers. The KSM8 excels across the board at both FOH and monitors, which is rare. This mic makes mixing the band’s IEMs, monitors, and FOH much easier. It brings high-end clarity naturally, without the need for additional processing and EQ.

Art Janota Top Freelance Engineer Las Vegas, Nevada

I used the wireless KSM8 for a corporate gig, and I love the off-axis response! The CEO got far away and off axis with minimal audible change. It was stable even in a very odd PA design. The working distance is huge on this mic and made my job so much easier!

Anne-Lise Coulet Monitor Engineer for Jennifer Lopez

The KSM8 capsule is a life-changer in monitor world, especially for in-ears. When Jennifer is moving between the PA, side fills, and the live band, and the audience starts screaming, the KSM8 gives me the clarity and control I need so that her vocal easily cuts through it all without bleeding.

Where should KSM8 be used?

KSM8 redefines dynamic microphone technology for leading performers and engineers. It virtually eliminates proximity effect and provides unmatched vocal accuracy with minimal EQ and processing and has been designed for use in large, complex sound systems. Providing absolute vocal clarity, KSM8 is suited for production studios, live performance venues and broadcast productions.

Characteristics of the KSM8

KSM8 has an extremely wide sweet spot, due to the design of the Dualdyne element and its ability to control proximity effect. Additionally, the neutral mid/high frequency response means that there is little external processing required, resulting in consistent, natural-sounding audio, regardless of the artist’s mic technique and placement.

How is Unidyne III different than Dualdyne?

The Unidyne III cartridge features a single diaphragm with a pneumatic shock mount. The advanced technology of the Dualdyne cartridge originates in the second diaphragm which has been added. Besides the active diaphragm, a second passive diaphragm has been implemented, which is part of the cartridge’s acoustic network that provides an unattained mastery of proximity effect.
