Expansion Microphone Kit for Poly Trio C

This expansion microphone kit is designed exclusively for the Poly Trio C conference system. It adds extra microphones to extend audio pickup in larger meeting spaces. Organisations that need every participant heard clearly in boardrooms or collaborative areas will benefit from the enhanced coverage. The kit integrates directly with the existing Poly Trio C unit.

Plug-and-play installation

The microphones connect to the Poly Trio C with simple plug-and-play functionality, requiring no software configuration. A common issue is attempting to use the kit with other Poly conference phones or third-party systems, which is not supported. Cable routing should be planned to keep the workspace tidy and prevent accidental disconnection during meetings.

Compatibility limited to Poly Trio C

The single specification that determines suitability is strict compatibility with the Poly Trio C conference system only. This kit will not function with any other conference phone model or brand. Buyers must verify they own a Poly Trio C before purchasing, as the connectors and protocol are proprietary to that specific unit.
