Beyerdynamic Classis RM 30 Desktop Condenser Microphone – Black Overview:

The Classis RM 30 is a desktop microphone for round table discussions, podiums, tele/video conferencing and lecterns. The vertical microphone array results in a horizontal corridor characteristic (horizontal cardioid, vertical lobe). This allows the speaker or conference participant maximum freedom of movement at a consistent intelligibility of speech. It is possible for two people to share one microphone. The vertical lobe polar pattern also optimises the gain before feedback in ceiling installations.
