48V conference microphone A-211
Delicate and elegant heart - shaped sound - picking head structure design, ergonomic, very modern atmosphere
Combined with acoustic space requirements (sensitivity level, directivity factor, directivity coefficient) has the patent of the extended microphone pick up head, so that the sound restoration degree is high, to achieve a longer pick up distance.
Designed to enhance sound pickup, conference, television broadcast, professional recording and other high quality requirements of sound pickup applications
A windproof sponge cover is attached to reduce the incidence of unpleasant blowing and other wind noises during speech
