Logitech GROUP Expansion Mics (Pair)
PRODUCT DESCRIPTION
Logitech GROUP Expansion Mics (989-000171) - 2 Years Local Warranty
Logitech GROUP Expansion Mics — Extend Audio Coverage for Larger Rooms
Logitech GROUP Expansion Mics (989-000171) add two extra microphones to a Logitech GROUP system, extending the speakerphone's conversation area from 6 m (20 ft) to 8.5 m (28 ft) in diameter so meetings of up to 20 people can be heard clearly without anyone huddling near the speakerphone.
Plug-and-Play Setup with Mute Control
The microphones are automatically recognised and configured simply by plugging them into the GROUP speakerphone. Each mic has its own mute button and LED indicators, and connects on a 2.4 m (8 ft) cable so it can be placed further down the table.
