Beyerdynamic MPR211 Revoluto Desktop Array Microprocessor Controlled BLK

The MPR 211 B is a modern desktop microphone, which is ideal for discussions, tele/video conferencing and announcements. The Revoluto technology with 17 integrated microphone capsules provides a so-called corridor characteristic, which ensures a wide range of good voice quality. Within this range the speaker can move freely, i.e. he/she can stand up or sit down, move his/her head and move towards or away from the microphone. On the left hand side the MPR 211 B provides an LED, which will illuminate when the microphone is switched on.
