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. PERFORMANCE CHARACTERISTICS Smooth, pronounced high-end response Upper mid-range sounds accurate and articulate without sounding harsh Reduced proximity effect Focused low-end response KSM9KSM9 3 MODEL VARIATIONS APPLICATION AND PLACEMENT The KSM9 provides superior sound in any application that demands reference quality audio. The KSM9 is the ideal microphone for touring musicians, regardless of venue. The frequency response of the two patterns on the KSM9 sound nearly identical, making it possible to choose a pattern most suitable for a given application. The cardioid pick-up pattern provides excellent sound isolation and gain before feed-back with minimal off-axis coloration. The narrower 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 to each other. General Rules for Microphone Use 1. Mute all microphone channels prior to plugging or unplugging XLR cables, switching polar patterns, applying pads, high pass filters or applying phantom power. 2. Aim the microphone toward the desired sound source and away from unwanted sources. 3. Place the microphone as close as is practical to the desired sound source. 4. Keep the distance between microphones at least three times the distance from each source to its microphone. 5. Place microphones as far as possible from reflective surfaces. 6. Use the fewest number of microphones as is practical. 7. If necessary, add a windscreen when using the microphone outdoors. 8. Do not cover any part of the grille with your hand.

This phenomenon, known as proximity effect, delivers a warmer, more powerful sound. Unfortunately, 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, however, provides vocalists with more consistent low-end response when adjusting microphone distance during performances. And the gradual, low-frequency roll-off of the KSM9 minimizes the distorted or “boomy” sound that typically results from very close proximity. Wind Noise The KSM9 has an integral wind and pop filter which provides excellent protection against most wind and breath noise. An optional foam windscreen is available for use in conditions such as high winds or close proximity to a “problem” vocalist. TWO POSITION SWITCH FIGURE 1 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 for- giving at picking up off-axis sound. See Figure 3. Supercardioid. The narrower pattern provides greater rejection of off- axis sound and maximum 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 5. Phantom Power The KSM9 requires phantom power and performs optimally with a 48 Vdc sup- ply (IEC-268-15/DIN 45 596). However, it will operate with slightly decreased headroom and sensitivity with power supplies as low as 11 Vdc. 5 Impedance A minimum load impedance of 800 ohms should be used for maximum signal handling and minimum distortion. The impedance may be as low as 150 ohms, but a reduction in output level and output clipping level will result.
