Shure KSM9 Consistent with legendary Shure microphone innovation, the KSM9 is the first handheld condenser with dual diaphragms and variable polar patterns. As a premium vocal microphone, the KSM9 captures vocal subtlety with extraordinary detail to deliver clear articulation, functional flexibility and precise vocal reproduction for live performance. Transformerless, Class A preamplifier circuitry and dual, gold-layered diaphragms capture a transparent sound, revealing every nuance and subtlety in a vocal performance. The KSM9 uses an advanced suspension shock mount to virtually eliminate handling noise even in the most demanding live environments.

FEATURES Dual 3/4" gold layered, low-mass Mylar® diaphragms provide superior frequency response and proximity control Dual polar patterns (cardioid and supercardioid) for maximum flexibility in a wide variety of performance applications Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response and no crossover distortion, while minimizing harmonic and inter-modulation distortions Advanced suspension shock mount system that isolates cartridge from handling and stand noise Subsonic filter eliminates rumble from mechanical vibration below 17 Hz Premium electronic components, including gold-plated internal and external connectors Integrated three-stage "pop" protection grille reduces plosives, wind, and other breath noise PERFORMANCE CHARACTERISTICS Extremely uniform polar response Extended frequency response Minimal self-noise Exceptional low-frequency reproduction Able to withstand high SPLs High output level No crossover distortion Superior common-mode rejection and suppression of radio frequency interference (RFI) APPLICATIONS The KSM9 is designed to capture and control the detailed sonic nuances of critical studio performance, while withstanding the punishment of professional live sound reinforcement. The frequency response of the two patterns are nearly identical, allowing performers to easily adapt to any venue. The cardioid pick-up pattern is ideal in live performances for musicians with in-ear monitors, providing a warm, full sound. This setting provides excellent gain before feedback, with minimal off-axis coloration. The supercardioid pick-up pattern provides maximum sound isolation and is ideal for applications in which there are high levels of ambient noise, or where multiple instruments or vocalists are close together.

PROXIMITY EFFECT Directional microphones progressively boost bass frequencies as the microphone is placed closer to the source. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. However, it usually requires the vocalist to maintain a consistent distance from the microphone in order to avoid changing the low-frequency response. The dual-diaphragm design of the KSM9 helps to control and minimize proximity effect, resulting in a more uniform low-frequency response. This allows the performer to move closer or further from the microphone with minimal changes in sound quality.

SELECTING A POLAR PATTERN Cardioid: Captures sound directly in front of the microphone and has the greatest rejection 180 degrees toward the rear. A cardioid pattern has a wider coverage angle, resulting in increased off-axis pickup. This is the most common pattern in studio recording and live-sound applications. Supercardioid: Captures sound directly in front of the microphone and has the greatest sound rejection at points 120 degrees toward the rear of the microphone. A supercardioid pattern has a narrower coverage angle of 115 degrees, resulting in increased off-axis rejection. This pattern is ideal for loud environments or applications when sound sources are very close together.
