CS2080 • Open conference system

It is a discussion system featuring free access, in which the Chairper-

son or Moderator's microphone has priority. It is suitable for conferen-

ces attended by up to 80 people, including the Chairperson.

The heart of the system is the CS2080 control and power supply unit.

It has been designed specifically for managing small discussion-only

systems with no need for an operator in the conference hall. Versatility

of the output connections and the independent front-panel level con-

trols for each audio signal input are the strong points of this control

unit. It can power up to 80 stations and has at disposal four RJ45

outputs for connecting the stations in cascade fashion (using CAT5e

SF/UTP cable). There is a 'MIC'/'AUX IN' input for connecting addi-

tional sources to the conference system such as wired microphones,

wireless microphone receivers or other sources of sound. It is possible

to provide a 12 V phantom power supply for the 'MIC' input. There

are double 'IN' and 'OUT' sockets for connecting a recorder. There is

a 'BOOSTER OUT' (XLR) output socket to which a power unit can be

connected for sound-broadcasting in the conference hall.
