The Plena 6-zone call station is a stylish high-quality call station with a stable metal base design, a flexible microphone stem and a unidirectional condenser microphone. It is intended for making calls to selected zones (1 to 6 and all-call) in a PA system built around the LBB 1925/00 system preamplifier. In addition to table-top use, the special design enables the unit to be neatly flush-mounted in desk tops.
Functions
This call station features selectable gain, a selectable speech filter and a limiter for improved intelligibility, even if the speaker moves in front of the microphone. Because the call station provides a balanced line level output, it can be positioned up to 100 m away from the amplifier, using CAT-5 extension cables. Dipswitches on the bottom of the call station can be used to select different pre- and post-call chimes, as well as the priority level. Selected zones are indicated with LEDs on the call station, and an additional bi-color LED gives visible feedback on the active state of the microphone and the system. Green indicates microphone on or chime active (flashing LED); amber indicates that the system is occupied by a source with a higher priority or operation error (flashing LED).
