Quick answers about the CCSD-FDL, and how it compares.
Which CCS 1000 D discussion device do I need?
| Device | Mounting | Microphone | Role | Size, weight |
|---|---|---|---|---|
| CCSD-DL2 | Tabletop | Long, 480 mm | Participant or chair | 50 x 150 x 132 mm, about 1 kg |
| CCSD-DS2 | Tabletop | Short, 310 mm | Participant or chair | 50 x 150 x 132 mm, about 1 kg |
| CCSD-DL | Tabletop | Long, 480 mm | Participant or chair | 64 x 203 x 146 mm, about 1 kg |
| CCSD-DS | Tabletop | Short, 310 mm | Participant or chair | 64 x 203 x 146 mm, about 1 kg |
| CCSD-FDL | Flush | Long, 480 mm | Participant | 63 x 173 x 92 mm, 560 g |
| CCSD-FCML | Flush | Long, 480 mm | Chairperson | 63 x 173 x 92 mm, 560 g |
All have a flexible-stem cardioid microphone, built-in loudspeaker and the white possible-to-speak light. Tabletop devices add a headphone socket. Short-microphone flush versions: CCSD-FDS (ask us), CCSD-FCMS (ask us).
How is the flush device installed?
It fits into a cut-out in tables up to 40 mm thick; a cut-out template and five wood screws are in the box. The 2 m cable with locking 6-pole connector and the loop-through socket daisy-chain the devices, up to 35 flush devices per trunk.
What do the lights on the device mean?
- White above the microphone button: you can switch your microphone on now.
- Green above the button and in the microphone head: your request is in the waiting list; it flashes when you are next.
- The microphone head has a light ring as well.
How do I set up a chairperson seat?
Tabletop devices ship with a participant microphone button. For the chairperson, clip on the chairperson buttons (microphone and priority) and set the concealed slide switch under the device to chairperson; no system restart. For the CCSD-DL2 and CCSD-DS2 the buttons are ordered separately: CCSD-DCBCM (ask us), 10 pairs with the removal tool. For the original CCSD-DL / DS, ask us.
Flush seats use the CCSD-FCML, a dedicated chairperson device with its own priority button.
The chairperson holds the priority button to overrule all participant microphones; a chime announces it. Up to 25 devices can be chairperson or interruption microphones.
Which discussion modes does CCS 1000 D have?
- Open: participants press to speak; when the open microphones are full, the next request joins the waiting list.
- Override: a new speaker switches off the microphone that has been on longest (never the chairperson).
- Voice activation: microphones switch on when someone speaks; hold the button to mute.
- Push to talk: the microphone is on while the button is held.
Up to 4 open microphones are set on the control unit, up to 25 in the web browser interface. An interruption microphone, for example at a podium, always gets the floor.
What do I need for a CCS 1000 D system?
- A control unit: CCSD-CURD with MP3 recorder and feedback suppression, or CCSD-CU (ask us) without them. It powers and controls up to 80 discussion devices on two trunks of 40.
- Extension units for bigger rooms: each CCSD-EXU powers up to 85 more devices, for a maximum of 245.
- Tabletop devices: CCSD-DL2 (long microphone) or CCSD-DS2 (short microphone), each set as participant or chairperson.
- Flush devices: CCSD-FDL for participants and CCSD-FCML for the chairperson, both with long microphones; short-microphone CCSD-FDS (ask us) and CCSD-FCMS (ask us). Up to 35 flush devices per trunk.
- A tablet, laptop or PC for the web browser interface and advanced settings.
Devices daisy-chain with their own 2 m cables and are plug and play: no restart when you add or remove one.
