Poly Trio Expansion Microphone

The Poly Trio expansion microphone connects to Poly Trio 8300 and 8800 conference phones to extend voice pickup in larger meeting spaces. It adds a dedicated microphone array so participants farther from the base unit are heard clearly. The accessory is supplied new and carries manufacturer part number 85X00AA.

Suitable for rooms needing wider coverage

This microphone suits organisations that already deploy Poly Trio 8300 or 8800 systems and need broader audio capture without adding another conference phone. It does not function as a standalone device and cannot connect to other phone models or USB audio interfaces. Buyers without a compatible Trio base unit should look at a different solution.

Compatibility with Trio 8300 and 8800

The single specification that determines fit is compatibility with the Poly Trio 8300 and 8800 conference phones. The microphone is designed exclusively for those two models, so verifying the exact base unit in use is the only check required before purchase.

Questions about this item

Does the Trio 8300/8800 Expansion Microphone require any periodic maintenance or part replacement?

The microphone is a passive accessory with no moving parts or consumable components, so no scheduled maintenance or replacement parts are needed during normal use.

What is the first limitation reached when the expansion microphone is used continuously in a large conference room?

The practical limit is the maximum number of expansion microphones the Poly Trio 8300 or 8800 base unit can support, which determines total coverage.

Does the 85X00AA expansion microphone add noticeable heat, fan noise or power draw when the system runs all day?

The microphone draws power directly from the base unit over its wired connection and has no internal fan or heater, so it adds negligible heat or noise.
