What is a good mic to use for a group of six standing in a semi-circle? This is for singing in a church - live sound.A semi-circle is difficult as the angle is 180 degrees. Cardioid mics, most often used for live sound, have a 120 degree pickup angle.
To cover 180 degrees and six people, we recommend mounting two identical models of the following mics on a Shure A27M stereo mic adapter (a device that holds two mics on one mic stand):
Best: SM81 or KSM137
Better: SM94 or KSM109
Please note that these mics require phantom power for your mixing board. Also note that these mics should be placed no closer that 12 inches to any singer's mouth.
