DIS Digital Discussion Systems
DC 5900 F Discussion Unit
Description
The DC 5900 F is a flushmount discussion unit for the DIS DDS 5900 Digital
Discussion System. It enables participants to address and monitor others in the discussion, while mounting unobtrusively onto the surface. The DC 5900 F is configurable as a chairman or delegate.
The modular design of the DC 5900 F allows component variations to expand or
simplify the system. A loudspeaker is available for listening to the discussion, while
a headphone output provides two language translation channels. Expanded microphone options offer greater flexibility and deliver superior audio performance.
Touch-button controls automatically configure as chairman or delegate, according to
the attached overlay.
Component Variations
The DC 5900 F is a system of modular
components that can be expanded or
simplified once the base unit has been
installed. The following is a description
of each component:
① Base
Each component connects to the
DC 5900 F base to assemble the
discussion unit. Two RJ-45 jacks
on the bottom provide power,
audio, and control across a chain of
discussion units.
② Front plate
The front plate includes the touchbutton controls. Two models are
available:
◦ FP 5921 F: speech only
◦ FP 5981 F: speech with
language interpretation
monitoring
③ Loudspeaker
The optional LS 5900 F loudspeaker
provides sound reinforcement of the
discussion.
④ Gooseneck microphone
The microphone enables
participants to address the floor and
is available in a variety of models:
◦ GM 59xx
◦ GM 6xxx
◦ Shure MX4xxRLP (requires AC
5901 XLR/Microflex adapter)
⑤ Touch-button overlays
The overlay attaches to the front
plate and automatically configures
the touch-button controls. Each
overlay provides specific controls
for operation as a delegate or
chairman. A blank overlay is also
available for participants that do not
require any controls.
