APPLICATIONS
The MPR 211 is a desktop microphone with many different functions.
Depending on the application, the operating mode ON/OFF, PushTo-Talk (PTT) or Push-To-Mute (PTM) can be selected at the bottom
of the microphone unit. The different functions are controlled by a
micro-controller.
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 the speaker can move
freely, i.e. can stand up or sit down, move his/her head and move
towards or away from the microphone.
The MPR 211 is turned on/off with a silent microphone button. The
illuminated LED on the microphone button and the LED on the left
hand side indicate that the microphone is ready to speak into.
The MPR 211 is ideal as desktop microphone for discussions,
tele/video conferencing and announcements.
The MPR 211 can also be operated with an external control
contact. As a choice the built-in microphone button is switched on
or off. An external device (e.g. mixing amplifier for announcements)
can be triggered via the control output when operating the microphone button (e.g. mixing amplifier for announcements). These
basic functions are possible: Autonomous, Remote and External
Logic.
