Bosch- Pleana 2 Zone Mixter 180W Amplifier

Fire Projects has installed sevaral installation of the Plena two-zone call station is a modern, high-quality call station with a stable metal base design, a flexible microphone stem and a unidirectional condenser microphone.

It can make calls to selected zones in a public address system built with the PLE series two-zone mixer and mixer amplifiers. In addition to tabletop use, the Plena design allows neat flush-mounting in desktops.
This call station features selectable gain, a selectable speech filter, and a limiter for improved intelligibility. The call station has a balanced line level output, giving it a maximum range of 200 meters from the mixer, when using CAT-5 extension cables. With the loop-through RJ-45 connector, it is possible to daisy chain multiple call stations.The priority is automatic i.e. the call station nearest the mixer has priority and can override a call station further from the mixer. When a call is being made by a higher priority call station, a yellow light will display on the lower priority call stations.
