Functions
The call station has a cardioid, supervised microphone on a gooseneck stem with good speech intelligibility. A limiter and a speech filter improve intelligibility and prevent clipping of the audio. It has a volume control for the monitoring speaker and the headset. When it plays a chime or a pre-recorded message, the call station activates its speaker. When a headset is connected, it replaces the microphone and speaker.
The call station has its own DSP, and converts between analog and digital audio. The audio processing can include sensitivity adjustment, limiting, and parametric equalization.
Controls and indicators
• Three status LEDs
• Configurable PTT-key
• Volume control for loudspeaker/headset
Interconnections
• Two system network connections
• Serial data and power supply interface for call station keypads
• 3.5 mm jack for headset
