An end-addressed large diaphragm condenser microphone with mechanically switching dual polar patterns (cardioid and omnidirectional).
Includes two KSM141, two foam windscreens, A27M Stereo Microphone Adapter, carry case
A mechanical polar pattern switch for highly consistent cardioid and true omnidirectional polar patterns
Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect
Three-position switchable pad (0 dB, 15 dB, and 25 dB)
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
Can withstand high sound pressure levels (SPL)
High output level
No crossover distortion

Polarity
Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
Power Requirements
1152 V DC [4]phantom power (IEC-61938) 4.7 mA, maximum
Net Weight
156 g (5.5 oz.)
[1]1 Pa=94 dB SPL
[2]THD of microphone preamplifier when applied input signal level is equivalent to cartridge output at specified SPL
[3]S/N ratio is the difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
[4]All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slightly decreased headroom and sensitivity.
