| Features |
KSM109/SL with windscreen and
zippered carrying case.
The Shure KSM109 offers incredible performance, combining an
extended frequency response for natural sound reproduction with a
smooth high end and a tight, controlled low end. It is all the
microphone you need for studio instrument recording. Other
features:
- A tight cardioid polar pattern
- Transformerless Class-A preamplifier circuitry
design
- Outstanding transparency without crossover
distortion
- An extended frequency response (20Hz to
20KHz)
- Natural reproduction of sound with a smooth high-end and a
tight/controlled low-end
- Switchable 15dB Pad allows the input of a wider range of
SPL sources
Some typical applications for the KSM109 are listed below,
but the microphone may be used for a variety of applications other
than those listed.
- Acoustic instruments -- such as piano, guitar, drums,
percussion, strings
- Wind instruments -- brass and
woodwind
- Overhead miking -- drums or
percussion
- Ensembles -- choral or orchestral
- Room ambiance pick-up -- guitar amplifier or
drums
Both the acoustic environment and microphone placement
strongly affect the sound obtained from miking a source. You may
need to experiment with microphone placement and room treatments to
achieve the best overall sound for each application.

Cardioid
- Output Impedance : 150 ohms
(actual)
- Attenuation Switch : 0 dB or 15
dB attenuation
- Phantom Power : 48 Vdc +/- 4 Vdc
(IEC26815/DIN 45 596), positive pins 2 and
3
- Current Drain : 5.2 mA typical
at 48 Vdc
- Common Mode Rejection : >50
dB, 20 Hz to 20 kHz

Hz; 1 Pa = 94 dB SPL) : -41 dBV/Pa
- Selfnoise (typical,
equivalent SPL; A-weighted (IEC 651)) : 19 dB
- Maximum SPL@ 1000
Hz
- 5000 ohms load (Attenuator on) :
150 (165 dB)

- Output Clipping
Level*
- 5000 ohms load : 15
dBV
- 2500 ohms load : 9
dBV
- 1000 ohms load : 3
dBV
- Dynamic Range (Attenuator
On)
- 5000 ohms load : 133 (136)
dB
- 2500 ohms load : 128 (130
dB)

dB
- Signal to Noise Ratio** : 75
dB
*20 Hz to 20 kHz;THD < 1%. THD of the microphone preamplifier
when applied input signal is equivalent to the cartridge output at
specified SPL.
**S/N ratio is the difference between 94 dB SPL and equivalent SPL
of self-noise A-weighted
