Rotating Polar Pattern Switch 0/15/25 dB Attenuation Switch Low Frequency Response Switch FIGURE 1. KSM141 CONDENSER MICROPHONE GENERAL DESCRIPTION ® The Shure 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 reco

USING THE KSM141 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. Cable Connections Use a cable with XLR co

Setting Low-Frequency Response A three-position switch on the KSM141 lets you adjust the low frequency response of the microphone. The low frequency filters can be used to reduce wind noise, room noise, or proximity effect. Refer to Figure 2. Flat response. This setting +5 provides the most natural sound 0 reproduction in most applicatons. Low-frequency cutoff. This setting provides an 18 dB-per-octave –10 cutoff at 80 Hz. It helps eliminate floor rumble and low-frequency noise produced
