KSM141 Dual Pattern Instrument Microphone |
|
|
Product Code:
KSM141 |
The KSM141 is a small diaphragm
end-addressed condenser microphone with a rotating collar
allowing easy switching between a highly consistent cardioid or
true omnidirectional polar pattern for smooth and extremely
focused sound reproduction.
Designed for studio use, yet rugged
enough for live applications, the KSM141 can withstand extremely
high sound pressure levels (SPL). Its low self-noise and
extended frequency response make it ideal for recording musical
instruments.

windscreen and carrying case, champagne finish
•KSM141/SL ST PAIR with two KSM141 mics, two windscreens, one
carrying case, champagne finish |

Features
- A mechanical polar pattern switch for highly consistent cardioid and
true omnidirectional polar patterns. Provides flexibility in a wide variety
of recording applications
- Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar® diaphragm
for superior transient response
- Class A, discrete, transformerless preamplifier for transparency,
extremely fast transient response, no crossover distortion, and minimal
harmonic and intermodulation distortion
- Premium electronic components, including gold-plated internal and
external connectors
- Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused
by mechanical vibration
- Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling
extremely high sound pressure levels (SPLs)
- Three-position switchable low-frequency filter to reduce background
noise and counteract proximity effect

Applications
Some typical applications for the KSM141 are listed below. Microphone use,
however, is a matter of personal taste. The KSM141 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
- Low frequency instruments -- such as double bass, electric bass, kick
drum
- 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.

Specifications |
- Cartridge Type :
Permanently Biased Condenser
- Frequency Response : 20 to 20,000 Hz
- Directional Polar Pattern : Cardioid/Omnidirectional
- Output Impedance : 150 ohms (actual)
- Attenuation Switch : 0 dB, 15 dB, or
25 dB attenuation
- Low Frequency Response Switch
Flat; -6 db/octave below 115 Hz;
-18 dB/octave below 80 Hz
- Phantom Power : 48 Vdc +/- 4 Vdc
(IEC26815/DIN 45 596), positive pins 2 and 3
- Current Drain : 4.65 mA typical at 48
Vdc
- Common Mode Rejection : >50 dB, 20 Hz
to 20 kHz
- Polarity : Positive pressure on
diaphragm produces positive voltage on output pin 2 relative to pin 3
- Dimensions and Weight : 20 mm (0.8
in.) diameter, 146 mm (5.75 in.) long; 156 grams (5.5 oz.)
- Sensitivity (typical, at 1000 Hz; 1
Pa = 94 dB SPL) : -37 dBV/Pa
- Selfnoise (typical, equivalent SPL;
A-weighted, IEC 651) : 14 dB
- Maximum SPL
5000 ohm load (Attenuator on): 145 (160, 170) dB
2500 ohm load (Attenuator on): 139 (154, 164) dB
1000 ohm load (Attenuator on): 134 (149, 159) dB
- Output Clipping Level*
5000 ohm load: 15 dBV
2500 ohm load: 9 dBV
1000 ohm load: 3 dBV
- Dynamic Range
5000 ohm load: 131 dB
2500 ohm load: 125 dB
1000 ohm load: 120 dB
- Signal to Noise Ratio** : 80 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 difference between 94 dB SPL and equivalent SPL of
self-noise A-weighted.
