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.
