Introduction
The Dual Delegate Interface is intended for use in flush
mounted custom solutions. It enables a number of functions
to be added, making it suitable for chairmen and delegates.
Such functions include facilities for connecting a Voting
Panel, with or without a Card reader (DCN-FVCRD or DCN-
FV). In addition, two separate audio inputs are provided that
can also be used as line inputs. Each input can be assigned
its own seat number, allowing the DCN-DDI to serve two
delegate positions.
Settings are available to assign the Dual Delegate Interface
for use as a delegate unit, a dual delegate, chairman unit,
entrance/exit unit or ambient microphone. The ambient
microphone is located in the conference venue, and
automatically switched on when no other delegate unit or
chairman unit microphones are active. In this way,
interpreters always have audio contact with conference
venue.
