Know before you buy
These microphones are specifically designed for the Poly RealPresence Trio series. They are intended to integrate directly with the Trio 8500 and 8800 conference phones.
By adding these two microphones, you significantly extend the audio pickup range of your base unit. This allows the system to effectively capture voices in larger conference rooms or at longer tables where the base unit alone might struggle.
The kit includes two 7-foot cables, which provide enough slack to position the microphones at opposite ends of a medium-to-large conference table. This placement ensures that participants sitting further away from the main console are still clearly heard.
No, these microphones are powered directly through the connection to your Poly RealPresence Trio conference phone. You do not need any additional power adapters or outlets to use them.
While these microphones deliver Poly HD Voice quality, they are primarily designed to extend pickup range rather than act as noise-canceling devices. They will help capture voices more clearly, but they are most effective in rooms with reasonable acoustic control.
