6. The front 3-position switch allows you to choose between:
• Single capsule cardioid (F, front capsule): ideal for interviews or lectures;
• Single capsule cardioid (R, rear capsule): ideal for podcasts or voice memos;
• Dual capsules (F+R, two capsules combined to form a figure-of-8 pattern): ideal for Q&A interviews and
every situation that requires to record audio source coming from front and back, isolating the side space.
Indeed, figure-of-8 microphones measure the difference in pressure between either side of an open
diaphragm. This meant that they were very sensitive to sound from the front and rear, but almost completely
deaf on the sides. On iRig Mic Cast HD this is obtained combining together the two cardioid capsules.
