Conference Techniques


With conference techniques it is important that every participant of the conference is able to understand the speaker. This is why you should invest in wireless microphones which provide perfect sound quality.

Just like with every wireless system, you need a receiver, a transmitter (base of the microphone) and a recording device (microphone). The microphone recognizes the sound waves produced while speaking and passes them, as electrical signals, on to the transmitter. The transmitter then broadcasts these signals over a wireless connection to the receiver with which the sound can be adjusted.

But you are not limited to the classic gooseneck microphones. With Sennheiser?s newest additions to conference techniques you can take online conferences to a new level.
