Is it possible to connect the polycom HDX ceiling microphone to Cisco SX80. Do I just need a RJ45 to Euroblock convertor to connect to Cisco SX80. Thanks.
You cannot directly use the Polycom microphone arrays, whether tabletop or ceiling, with other systems directly.
The microphone array uses digital communications to communicate with the connected Polycom equipment.
To use these digital microphone arrays with other vendor’s equipment is possible by using the Polycom SoundStructure. It provides an analog output that can be used with other vendor’s equipment.
