The basic system
The image below shows the products of a basic audio-only Close Talk
Conference System:
The basic system consists of a number of Delegate Units, usually one
per participant, one
Central Unit, one or more Transceivers with cabling and finally a
battery charger solution.
There
are three mounting variants available for the transceiver, surface mounting by
screw, flush mounting by spring and flush mounting by screw fastening. The
transceivers are designed to be non-intrusive with their neutral white color and
blends with most ceiling types. Other colors are available on special order.
Close Talk Conference System works with ceiling heights up to seven meters, in special cases even
higher.
There are two alternatives available for battery charging, the
cord charger DC-110-45 that supports five units per charger and a
combined transport and charger trolley CT-10 that supports up to twenty-four units per trolley.
The transceiver is mounted face-down in the
ceiling, directed towards the delegate units and is connected to the central
unit using industry standard S-STP Cat. 6 Ethernet cables. The
transceiver works like an antenna for the signals to and from the delegate
units, one or more transceivers are used to support the desired area of
operation.
The system supports an unlimited number of delegate units with
a maximum of three active microphones at one time. There is no special chairman
unit, any unit can be promoted to chairman functionality by settings in the
central unit. Audibility can be further increased by connecting the system to an
external PA.
The delegate units 'talks' to the central unit via the
transceiver, using infrared light. No cords, not even power cords since the
delegate units are battery powered. The
delegate units sleek design will fit into almost all environments.
