Know before you buy
Quick answers about the CCSD-EXU, and how it compares.
When do I need a CCSD-EXU?
When you have more than 80 seats. Each extension unit powers up to 85 more devices, up to 245 in one system.
How is it connected?
Its cable plugs into the control unit or the previous extension unit. It has three outputs for devices and a loop-through for the next extension unit.
What is in the box?
Extension unit, mains cord, power supply, tabletop feet, 19-inch rack brackets, quick guide.
Does the camera follow the speaker?
Yes. With the optional Unear V51X network camera, the control unit steers the camera over the network to the seat whose microphone is on. When the microphone goes off, the camera returns to the room view. No operator is needed.
What do I need for a system?
A control unit (CCSD-CURD). One discussion device per seat: tabletop CCSD-DL2 or DS2, or flush-mounted CCSD-FDL and CCSD-FCML. For more than 80 seats, add a CCSD-EXU extension unit. Optional: the Unear V51X camera that follows the speaker.
Who supplies Bosch CCS 1000 D in Pakistan, and what warranty do I get?
