Bosch PLE‑2CS Plena Two-zone Call Station, metal base design, a flexible microphone stem with a unidirectional condenser microphone and zone selection, Nominal sensitivity : 85 dB SPL, Nominal output level : 700 mV, Input sound level (max) : 110 dB SPL, Frequency response : 100 Hz to 16 kHz

Gain, Speech Filter and Intelligibility

This call station features selectable gain, a selectable speech filter, and a limiter for improved intelligibility.


With the loop-through RJ-45 connector, it is possible to daisy chain multiple call stations.


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.

Controls and Indicators

 2 x status LEDs, PTT key, 2 x zone selection keys, DIP switches

 Rotary volume control, 2 x zone selection LEDs

Dip Switches and Status

DIP switches at the base of the call station select different microphone gain levels, chimes, and the speech filter. 


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
