KSM8 DUALDYNETM

Get the sound right at the source

Dual-Diaphragm Cardioid Dynamic Vocal Microphone

The KSM8 functionally eliminates the proximity effect while offering a neutral frequency response that one might typically expect from a condenser microphone, all while providing what Shure describes as "the single purest cardioid polar pattern Shure has developed to date." It accomplishes this with its dual-diaphragm capsule — its active, front-facing capsule is responsible for its accurate, true-to-source frequency response, while the second passive capsule (when coupled with the inverted airflow system) helps eliminate the bass-boosting proximity effect. As a result, the KSM8 requires very little to almost no signal processing.
These elements result in accurate sonic capture while increasing the area of pickup where the mic sounds its best, known as its "sweet spot." When used for vocal applications, this benefits those with microphone-handling experience, as well as those with none.

KSM8 DUALDYNETM

Broadcast
Thanks to its wide sweet spot, nearly nonexistent proximity effect, and low handling noise due to its Diaphragm Stabilization System, the KSM8 holds great appeal for broadcast applications, especially in situations concerning talent with minimal handheld microphone experience. These design features result in consistent frequency reproduction and low handling noise, helping make the sound team's job easier.
Live Sound Reinforcement
Its large sweet spot and tight cardioid polar pattern offer an attractive combination for live sound engineers, providing front of house with accurate capture that can require less processing at the board. A part of Shure's legacy of renown, the KSM8's rugged housing is designed to assure it stands up to the rigors of daily live use.
Studio
Like many of its dynamic predecessors designed for broadcast, engineers and recording artists will quickly find the KSM8 to be a valuable asset in the professional and project studio. Its condenser-like frequency response, coupled with the ruggedness of a dynamic mic, allows the KSM8 to be at home in front of a variety of sound sources, including vocals, guitar cabinets, drums, horns, and more.

Q

What is the "sweet spot"?+-

The "sweet spot" is an audio term that refers to the particular placement of a microphone in reference to the sound source for the most natural and balanced sound. For vocal microphones this is notable as the sound quality can vary dependent on how the artist is holding the microphone. If the artist is holding the mic too close the audio can typically sound more muddy or unclear. Conversely, if the microphone is too far away, the audio can sound thin and distant. The 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 of the KSM8 means that there is little-to-no external processing required, resulting in consistent, natural-sounding audio, regardless of the artist's mic technique and placement.

How does the KSM8 compare to the SM58, or the Beta 58A?+-

All microphones serve various applications - no one microphone is the solution to every problem. Within the KSM8 introduction and conversation, it is important to remember that the SM58 is still consistently chosen for a wide variety of vocal applications from the lowest to the highest tier of consumers as the standard by which other microphones are measured. Additionally the Beta 58A was designed for increased gain before feedback due to its supercardioid polar pattern, and offers a higher output and hardened grille. However, in terms of sound reinforcement, the KSM8 is able to address the issue of proximity effect in a way that no other dynamic microphone has ever been equipped to manage.

Q

A

Aren't condenser microphones superior to dynamic microphones?+-

No, they are simply different tools for different situations. Condenser microphones offer exceptional detail and sensitivity, but can be challenging for loud stages due to bleed and gain before feedback that can be a result of that higher sensitivity. Dynamic microphones offer great sound quality and are consistent in their performance - a key choice for a wide variety of loud stages, regardless of size, and chosen for increased gain before feedback. However, the perception that condenser microphones are superior is incorrect in particular when discussing Shure products as both Shure condenser and dynamic microphones are built to the same exacting standards of durability, ruggedness and sound quality regardless of environmental conditions.

How is Unidyne© III different than Dualdyne?+-

The Unidyne III cartridge features a single diaphragm with a pneumatic shock mount. At the time of the SM58s introduction in 1966, this was a groundbreaking product that redefined the industry's understanding of handling noise by rendering it negligible. The Unidyne III cartridge has yet to be bettered in this regard. The Dualdyne cartridge design features two diaphragms, one active and one passive. The passive diaphragm is part of the cartridge's acoustic network that provides a previously-unattained mastery of proximity effect. A brand new design from the ground-up, The KSM8 nevertheless incorporates key design learnings from the Unidyne cartridge, including a new iteration of the pneumatic shock mount, designed for detailed interface of with the Dualdyne cartridge.
