Description

The Classis Classis RM 31 is a desktop microphone for round table discussions, podiums, tele/video conferencing, announcements and lecterns. The Revoluto technology with five 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 microphone features the innovative Scudio technology, making it absolutely insensitive to wireless communication devices such as mobile phones.

With the Classis RM 31 RC you can select via the programmable button between the operating modes ON/OFF, Push-To-Talk and Push-To- Mute. The microphone button can also be disabled. The frequency response can be set with a separate switch in two stages: Linear or with low-cut filter to suppress low-frequency interference. The illuminated ring indicating the microphone status can be deactivated. In addition the Classis RM 31 RC provides the option of external control. Furthermore, when operating the microphone button, an external device can be controlled via the control output. The LED ring displays the ready-to-talk status of the microphone.
