Apart has released a tabletop discussion system that is designed to be flexible and easy to set up and use.
The Microphone Discussion System consists of a chairman unit (MDS.CHAIR) and up to 19 delegate units (MDS.DEL). The connection interface (MDS.INT) is located at the beginning of the microphone chain.
It has a circuit loop design which uses standard CAT5 cables to link up to 20 units in a daisy chain (every microphone and switching adaptor can be located anywhere in the loop).
