The dual representative interface is suitable for user customized embedded installation solutions. It allows you to add a variety of functions to meet the needs of conference chairs and delegates. These features include facilities for connecting voting panels (with or without card readers) (dcn-fvcrd and dcn-fv). In addition, it also provides two independent audio inputs that can be used for line input at the same time. Each input can be assigned its own seat number so that dcn-ddi can be used by two representative seats. Through setting, the dual representative interface can be used as single representative machine, dual representative machine, chairman machine, attendance / withdrawal device or venue microphone. The venue environment microphone is located in the venue. When there are no other delegates or chairman microphones active, it will turn on automatically.
