(Loading the full tour might take some seconds depending on your internet connection.)

All you need for conducting a successful discussion event

Elegant design, simple and intuitive to use with multiple possibilities of controlling the system. The plug and play simplicity of the system enables users to fully focus on the event.

The system consists of a central unit and single programmable multi-user type units, enabling discussion, interpretation, grouping, VOX (voice activation) and encryption.

Conferencing, two language interpretation and language distribution

Facilitating conferencing, two language interpretation and language distribution, the DDS 5900 covers the majority of all discussion events. For system set up, assigning of seats, operation modes etc. DIS provides you with a web browser interface, which in addition can be used for event management purposes during an event.

All the functions mentioned above draw a clear picture that when it comes to organising smaller size events, the cost effective DIS DDS 5900 is the right solution - due to its simplicity and high intelligibility.

An extension power supply for increasing the systems capacity in the DDS 5900 or DCS 6000 Systems.
DCS-LAN Kit The power kit consist of one PS CU and one PI 6000 which together provides additional power capacity.
The RP 6004 Repeater unit splits one DCS-LAN chain into four chains. The signal is regenerated to extend the maximum cable length.
The junction box can be used with either the DDS 5900 or the DCS 6000 systems.
In connection with the PS CU Power Supply, the PI 6000 Power
Inserter is used to provide additional power capacity for up to 40
conference units or interpreter units or up to 80 channel selectors in
one chain connected to the DCS-LAN.
The PS CU Power Supply is designed for use with DIS Central Units
CU 61xx and CU 59xx. One PS CU Power Supply is as standard
delivered with each central unit.
In connection with PS CU Power Supply the RC 6000 Redundancy
