Bosch PLE-1CS Plena All Call Station with PTT Condenser Tabletop Microphone Overview:The Plena tabletop microphone is a stylish, highquality tabletop unidirectional condenser microphone, intended for making calls in a public address system. Its heavy metal base and rubber feet ensure stability on any flat surface. The special design also allows the unit to be neatly flush-mounted in desktops. The PTT-key (press-to-talk), not only switches on the microphone, but also provides priority contacts, that are compatible with the Plena range of amplifiers. The switching characteristic of the PTT-key can be configured internally for PTT-mode (on as long aspressed) or toggle-mode (press to switch on, press again to switch off).It is equipped with a fixed, flexible 2 m cable and a 5‑pin Euro style connector for the balanced signal and the priority contact. If the priority contact is not required, the microphone can be connected to amplifiers with 3‑pin Euro style connector. A green LED indicates when the microphone is active.Specifications:Electrical
