KSM9

GENERAL DESCRIPTION

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.

PERFORMANCE CHARACTERISTICS

• Smooth, pronounced high-end response

• Upper mid-range sounds accurate and articulate without sounding harsh

• Reduced proximity effect

• Focused low-end response

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.

USING THE KSM9

Proximity Effect

In general, unidirectional microphones progressively boost bass frequencies

up to 10 to 15 dB (at 100 Hz) as the microphone approaches 6 mm (1/4 in.)

from the sound source. 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.

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.
