Shure KSM9/CG User Manual

OVERVIEW

KSM9

The Shure KSM9 is a dual-pattern (cardioid and supercardioid) handheld condenser microphone. Designed expressly for live vocal performance applications, the KSM9 removes the boundary between the studio and stage, offering the finest and clearest performance on modern high-end touring systems. The large dual diaphragm provides consistent polar response across the entire frequency range, for higher gain-before-feedback and minimal proximity effect for clear vocal reproduction.

FEATURES

• Dual 3/4” gold layered, low mass Mylar® diaphragms provide superior frequency response.

• Dual polar patterns (cardioid and supercardioid) for maximum flexibility in a wide variety of performance applications.

• Class A, discrete, transformerless preamplifier provides transparent, extremely fast transient response with no crossover distortion and minimal harmonic and intermodulation distortion.

• Advanced suspension shock mount system that isolates cartridge from handling and stand noise.

• Premium electronic components, including gold-plated internal and external connectors.

• Three-stage grille reduces “pop” and breath noise

SUPERCARDIOID RESPONSE GRAPHS

Cardioid. Is most sensitive to sounds directly in front of the

microphone and is least sensitive to those in back. Cardioid is the most commonly used pattern in live sound applications. Its slightly wider pick-up pattern is more forgiving at picking up off-axis sound. See Figure 2.

Supercardioid. The narrower pattern provides greater rejection of off-axis sound and maximun gain before feedback. The supercardioid pattern is ideal for use in loud environments or applications in which sound sources are very close to each other. See Figure 4.

Phantom Power

The KSM9 requires phantom power and performs optimally with a 48 Vdc supply (IEC-268-15/DIN 45 596). However, it will operate with slightly decreased headroom and sensitivity with power supplies as low as 11 Vdc.
