Shure KSM8 Dualdyne Cardioid Dynamic Vocal Microphone

patented Dualdyne cartridgeThe premium KSM8 Dualdyne Cardioid Vocal Dynamic Microphone is the world’s first-ever dual-diaphragm dynamic handheld microphone, a groundbreaking feat of engineering design and meticulously crafted for revolutionary vocal reproduction and sound-reinforcement control for world-class live performance in top-tier professional venues. Featuring the single purest cardioid polar pattern that Shure has developed to date, the patented Dualdyne cartridge of the KSM8 virtually eliminates proximity effect and masters off-axis rejection while providing sound professionals the signal clarity typical of condenser microphones without processing, along with the reliability of dynamic microphone feedback control.
Why It’s Better

CHARACTERISTICS OF THE KSM8KSM8 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.

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 and provides mastery of proximity effect.
Quality That’s in the Details
Amazing Features
• Patented cartridge design featuring two ultra-thin diaphragms (one active and one passive).
• Accurate frequency response due to controlled proximity effect which allows for neutral mid-and-high frequency reproduction
• 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.
• The Dualdyne cartridge re-images the Shure Pumping Pneumatic Shock Mount design with specific resistances.
• Patent Pending Diaphragm Stabilisation System (DSS) Technology protects and stabilizes the active diaphragm.
• Cutting-edge cartridge manufacturing methods utilise ultra-sonic and internal laser welding to provide best-in-class.
• Neodymium magnet resides in a micro-injection mold of aerospace SoftMag material that maximises the magnetic field.
• Dent-resistant, hardened carbon-steel grille design lined with hydrophobic woven fabric.
