DDS 5900 Digital Discussion System
WHAT GREAT SOUND
LOOKS LIKE.
Raise your expectations,
not your voice.
Whether your meetings let people innovate, educate, or
legislate, effortless and effective communication is key to
getting the job done.
With clear sound and simple setup, the Shure DDS 5900 Digital Discussion System
makes it easy to hear and be heard, without shouting or straining.
The DDS 5900 combines the microphone, loudspeaker,
interpretation audio, and user controls in an integrated system.
Now with a choice of both flush-mount and portable discussion
units, the DDS 5900 enables meeting participants to hear each
other clearly or join in videoconferences. Easy to configure and
expand, the DDS 5900 is equally at home in historic buildings
and contemporary meeting spaces. It’s the ideal all-in-one
audio solution for:
• Corporate meeting rooms
• City councils and regional government bodies
• Educational institutions
• Courtrooms
• Non-profit organizations
Why use a discussion system?
Sound Quality
Scalable Hardware
Plug-and-Play Simplicity
The DDS 5900 system delivers
consistent sound quality everywhere
in the room, regardless of room size or
acoustic conditions.
The DDS 5900 system can be expanded
to accommodate up to 250 users as
your needs grow.
Discussion units connect in a ‘daisychain’ using standard shielded CAT5e
cables, so setup is quick and easy.
Convenience
Global Capability
Secure Audio Transmission
The DDS 5900 allows for simultaneous
interpretation of two additional
languages heard through headphones
connected to the discussion unit.
The system is fully digital, and audio
is scrambled to prevent eavesdropping.
Microphones can be voice-activated,
push-to-talk, or controlled by the
meeting leader. A light ring on each
microphone indicates who
is speaking.
Control
Control the system using your
smartphone, tablet, PC, or a third-party
room control system.
Complete Flexibility
Add wireless microphones for
presenters, an audio recorder, or an
external PA system for the audience
as needed.

CU 5905
Central Unit
The CU 5905 is the “brain” of the DDS 5900
system. It powers up to 60 discussion units,
and can control up to 250 units. It keeps track
of microphone activation, encrypts the audio,
and routes floor and interpreter audio to each
discussion unit. An extra input lets you add a
presenter wireless mic or audio playback; extra
outputs can connect to a videoconferencing
system, audio recorder, or audience PA system.
Included Browser-Based Interface
Accessible from your smartphone, tablet, or PC*
Before the meeting, select the microphone activation mode, enter
the names of meeting participants, and configure external audio
inputs and outputs.
During the meeting, the meeting leader or an administrator can
monitor and control microphone activation from the screen.
* Smartphones and tablets require WiFi access point, not included
NEW DC 5900 F Flush Mount Discussion Unit
For permanent installations that demand a sleek
appearance, the DC 5900 F Flush Mount Discussion Unit
offers a compact footprint with no visible wiring.
The DC 5900 F uses an innovative modular design that
provides numerous configuration options to suit a wide
variety of applications.
Automatic Configuration
Microflex® Microphone Compatibility
The DC 5900 F is the first conferencing unit to
automatically configure itself as a Chairman or Delegate
unit. Sensors in the front plate detect which button overlay
has been attached, which dictates how the unit operates.
The DC 5900 F discussion unit is compatible with GMseries gooseneck microphones and selected Microflex
gooseneck models (adapter required). This gives system
designers expanded options to select the most appropriate
polar pattern and gooseneck length for the room acoustics
and table layout.
Flush Mount Discussion Unit Configuration
A base unit mounts securely in a round
hole drilled in the table surface.
A front plate – available with or without
interpretation audio monitoring - attaches
to the base unit.
A button overlay attaches to the front plate,
providing user controls and indicators.
A gooseneck microphone plugs into the
base unit, and can be locked in place.
An optional loudspeaker mounts to the
table, and provides sound reinforcement.
