Dcn-con is a standard conference device for delegates that allows them to speak, record requests for statements, register responses to requests, listen to others and vote. It is less sensitive to interference from mobile phones. It provides sockets for connecting pluggable microphones (dcn-mics and dcn-micl, which need to be ordered separately). Flat panel speakers provide minimal feedback on the super sound effects, thus improving speech clarity. When the microphone is activated, it will automatically mute. When the device is not in use, the speaker panel can be easily folded. It provides five voting buttons for all voting types. It also has an external interface to connect to an external fingerprint reader.
