Beyerdynamic Classis RM 31 Q Vertikal arraymicrofon for Quinta/Orbis units

Description

The Classis s RM 31 Q is a new desktop microphone for round table discussions, podiums, tele/video conferencing, announcements and lecterns.
The Revoluto technology with integrated microphone capsules provides a so-called corridor characteristic which ensures a wide range of good voice quality. Within this range up to two speakers can move freely, i.e. they can stand up or sit down, move their head and move towards or away from the microphone. The Classis RM 31 Q is used with the Quinta and Orbis microphone units. The LED ring of the Classis RM 31 Q illuminates red to indicate the ready-to-speak status of the microphone.

Features:

Horizontal corridor characteristic for picking up two speakers
Large speaking distance
Large freedom of movement
Revoluto technology with vertical microphone array
RFI-proof due to Scudio technology
High gain before feedback
Modern metal housing
