ไมค์ประชุมแบบก้านยาว 31 ซม ยี่ห้อ BOSCH รุ่น CCSD-DS

Discussion Devices are connected in a daisy‑chain configuration to the Control Unit (CCSD‑CU or CCSD‑CURD) of a CCS 1000 D Digital Discussion System. Their plug‑and‑play functionality allows them to be conveniently connected to and removed from the system as required. A power down or restart of the system is not necessary, which ensures fast installation and reconfiguration times. Participants can take part in a discussion by speaking into the microphone and listening to proceedings through the built‑in loudspeaker or (optional) headphones.
