What size room the AVer FONE540 covers, how many people it suits and when you need extra microphones.
Short answer
We recommend it for small rooms (4–6 people) and medium rooms (6–10 people).
The specs that decide room size
| Microphones | Two omnidirectional, 360° pickup |
| Expansion | Daisy-chain up to three speakerphones or four microphones |
How room sizes map to people
| Room type | Typical people | Typical size |
|---|---|---|
| Huddle | 2–4 | 80–150 sq ft |
| Small (this one) | 4–6 | 150–250 sq ft |
| Medium (this one) | 6–10 | 250–400 sq ft |
| Large | 10–16 | 400–600 sq ft |
General industry guidance; furniture, room shape and acoustics change what works.
When to add microphones
AVer: daisy-chain up to three speakerphones or four microphones. Daisy-chain a second FONE540 or add expansion mics to cover tables longer than about twice its pickup range.
