Poly Trio 8500 Expansion Microphones (Pair)

The Poly 85X00AA is a pair of expansion microphones engineered for the Poly RealPresence Trio 8800 conference phone. By adding these microphones, you give your meeting space an extra twenty feet of voice pickup on each side, so people seated at the far ends of a long table can speak in a normal tone and still sound clear to everyone on the call.

Each microphone is attached to a seven-foot cable, letting you place it exactly where it needs to be. Slide one toward the whiteboard, move the other closer to the back row, or angle both toward an audience facing a screen. The added reach helps you shape the coverage to fit boardrooms, training rooms, and other areas where a single tabletop unit may leave voices at the edges underrepresented.

Setup stays simple: plug the microphones into the Trio 8800 base and the system recognizes them automatically. Because they share the same black finish and low profile as the primary unit, they blend into the room without drawing attention, keeping the focus on the conversation rather than the hardware.

Teams that host client presentations, hybrid brainstorms, or regular status meetings will appreciate how these microphones eliminate the need for raised voices or repeated statements. Remote participants hear every comment the first time, which cuts down on disruptions and keeps discussions moving smoothly.
