Shure KSM141/SL Dual-Pattern Studio Condenser Microphone
The KSM141/SL Stereo from Shure is a switchable polar pattern, condenser studio microphone pair designed for instrument recording and sound reinforcement. The microphone capsule is switchable between a true omni-directional and a cardioid pattern using a rotating collar. The omni-directional pattern offers a greater pick up area, while cardioid offers attenuation of noise and ambiance at the off-axis sections of the microphones.
