The best microphone for a large conference room is an expandable system that puts mics close to every seat, not a single bar at the front. Good choices are Logitech Rally Mic Pods for Rally rooms, Poly Studio A2 table mics for Poly rooms, and the AVer FONE700 ceiling system for USB rooms. Plan on roughly one mic per 6-8 seats.
Why large rooms need extra mics
A video bar's built-in mics typically cover the front part of a room. Beyond that, voices sound distant and pick up more room echo. Large rooms (roughly 12-20+ seats, 20 ft / 6 m or longer) need mics distributed along the table or overhead.

Best for Logitech rooms: Rally Mic Pods
Rally Bar and Rally Plus rooms expand with Mic Pods. Use the Mic Pod Hub to branch cables in a star layout and the extension cable for long runs. Rally Plus includes two speakers, which helps sound reach the far end of a long table. See Logitech conference room audio.
Best for Poly rooms: Studio A2 and IP mics
Poly's Studio A2 daisy-chains along a long table, up to 8 per room. G7500 and Studio G62 rooms can use PoE IP table or IP ceiling mics. The Poly Studio X72 and V72 bars accept the Studio Table Microphone.
Best for USB and BYOD rooms: AVer FONE700
If the room runs on a PC or laptop, the FONE700 gives ceiling coverage plus a DSP hub over one USB connection. It works with any meeting app.
Best wireless option
Truly wireless conference mics are rare because they add latency and battery management. For presenters, add a lavalier system into a DSP. See wireless conference room microphones and wireless presenter microphones.
How many mics do you need?
| Room | Seats | Typical mic plan |
|---|---|---|
| Medium | 6-10 | Bar mics, plus 1 expansion mic at the far end |
| Large | 10-16 | Bar + 2 expansion mics, or 2 ceiling zones |
| Boardroom | 16-24 | 3-4 table mics along the table, or 3-4 ceiling arrays |
| Training / divisible | 24+ | DSP-based ceiling system, designed by an integrator |
Echo-prone rooms with glass and hard floors need treatment too. See large conference room audio, how to daisy-chain conference mics and best conference room audio systems.
