Conference system is a system that allows a large number of participants to use individual desktop microphone on a flexible stem. Feature of the conference system is the low number of wires and switching. When using a conventional desktop microphones from each of them must be laid in a separate cable across the room to a mixing console. You also need to have a mixer with a lot of mic inputs (up to 100 entries!), Which is extremely difficult and costly.
Conference system allows you to connect microphones on a chain one after another small cable length of 2 meters. Thus it is possible to set from 1 to 100 or more microphones, stretching from the mixer is just one cable.
