Poly Studio Expansion Mic Cable Extender Kit – 875M4AA

Product Overview

The Poly Studio Expansion Microphone Cable Extender Kit (875M4AA) enables extended microphone placement in large conference rooms by allowing you to use standard Ethernet cables to connect Poly Expansion Microphones up to 30 meters (98 feet) from your video conferencing system. The kit includes a pair of 2-meter dongles and a power adapter for reliable signal transmission over longer distances.

Designed for use with Poly Studio X50, X52, X70, V52, V72, and Studio USB video bars, this extender kit provides flexibility in microphone positioning to ensure optimal voice pickup in boardrooms and large meeting spaces where standard cable lengths fall short.

Who Should Use This Product?

Large Conference Room Managers

Ideal for facilities teams managing boardrooms and training rooms where expansion microphones need to be positioned far from the video bar for optimal voice coverage.

AV Integrators

Essential for professional installers deploying Poly Studio systems in large venues where standard microphone cable lengths are insufficient.

Why Choose This Product

The Poly Studio Expansion Microphone Cable Extender Kit solves the challenge of microphone placement in large meeting spaces where standard cable lengths limit positioning options. By leveraging existing Ethernet infrastructure, the kit enables flexible microphone placement up to 30 meters from the video bar, ensuring every participant is heard clearly regardless of room size or seating arrangement.
