English Rotating Polar Pattern Switch 0/15/25 dB Attenuation Switch Low Frequency Response Switch FIGURE 1. KSM141 GENERAL DESCRIPTION The ShureR KSM141 is an end-addressed condenser microphone with mechanically switching dual polar patterns (cardioid and omnidirectional). 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.
PERFORMANCE CHARACTERISTICS English SExtended frequency response SLow self-noise SExceptional reproduction of low-frequency sounds SCan withstand high sound pressure levels (SPL) SHigh output level SNo crossover distortion SUniform polar response SSuperior common mode rejection and suppression of RFI (radio frequency interference) MODEL VARIATIONS KSM141/SL KSM141/SL ST PAIR One KSM141 Condenser Microphone Two KSM141 Condenser Microphones One A141C Carrying Case One A141SPC Carrying Case One A100WS
USING THE KSM141 English Mounting the Microphone To secure the KSM141 to a floor stand or boom, thread the mount onto the microphone stand and insert the microphone into the microphone clip. Power Requirements This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-268-15/DIN 45 596). It can operate on voltages as low as 11 Vdc, but headroom and sensitivity will be decreased slightly. NOTE: Most modern mixers provide phantom power.
Setting Low-Frequency Response A three-position switch on the microphone lets you adjust low frequency response. The low frequency filters can be used to reduce wind noise, room noise, and proximity effect. Refer to Figure 2. Low-frequency cutoff. This setting provides an 18 dB-per-octave cutoff at 80 Hz. It helps eliminate floor rumble and low-frequency noise produced by heating and air conditioning systems.
