Description
The CM 6680 F is a fully digital flush-mounted conference unit in the DIS DCS
6000 Digital Conference System.
The unit is designed as a full featured conference unit with a chip card reader, vot-
ing and channel selector functionality. It features a microphone button, a delegate
off button, a chip card reader, five voting buttons, a headphone jack, channel se-
lector, a loudspeaker and a lockable XLR microphone connector.
The microphone button enables the user to activate/deactivate the microphone. A
button LED indicates when the microphone is on.
The delegate off button enables the user to turn off all active delegate micro-
phones, A button LED indicates that the button is activated.
The floor channel is distributed through the built-in loudspeaker, except when the
microphone is turned on. The user can also listen to the floor channel by inserting
headphones in the headphone jack and adjusting the volume with the volume but-
tons. Optionally, the channel selector can be used for listening to an interpretation
channel.
The voting buttons enable the user to participate in attendance checks and 3-but-
ton or 5-button voting sessions. Attendance checks and voting sessions are started
from the SW 6000 or a DC 6990P conference unit.
The use of the unit can be restricted by using the login with chip cards feature.
Chip card login is enabled from the SW 6000 and hence only available in combina-
tion with the SW 6000.
The CM 6680 F can be used in combination with the gooseneck microphones GM
652x or GM 6622 or the boundary microphone BM 6620.
The gooseneck microphones GM 652x or GM 6622 can be locked to the unit with
a 2 mm hex key. The lock is accessible from the small hole to the right of the XLR
socket. Turn the hex key clockwise to enable the lock and insert the gooseneck
microphone into the XLR socket. Turn the hex key counter clockwise to disable the
lock and remove the gooseneck microphone.
The boundary microphone BM 6620 can be retrofitted by replacing the XLR insert
in the plastic adaptor with the boundary microphone. The molex mini-connector fits
with the microphone connector on the PCB.
