Thanks to three optional installation variants the microphone can be mounted on any ceiling while the DSP is hidden away in the cabinet and the loudspeakers are mounted freely in the room. Because of this, the tables remain free from cables and there are no requirements of a fixed table positioning. The ceiling microphone covers up to 60 m².
