Yealink A30, A40 or A50: Which Teams Rooms Bar Does Your Room Actually Need?

When NZ businesses start exploring Microsoft Teams Rooms, the first hardware question is almost always: which bar do I need? The Yealink A-Series — A30, A40, and A50 — are all certified Teams Rooms devices that run the same Teams Rooms operating system and integrate natively with Microsoft 365. But they're built for meaningfully different rooms, and choosing the wrong one either wastes budget or leaves your meeting room underserved.

The Yealink A30 — Small Rooms and Huddle Spaces

The A30 is designed for rooms seating two to six people: focus rooms, small team meeting spaces, manager offices, and consultation rooms. It's a compact all-in-one bar with:

• 120° ultra-wide camera — covers the full width of a small room or huddle table without needing to pan
• Dual built-in microphones — four-metre pickup range, sufficient for a table of four to six people
• 20W speaker — clear audio fill for a small room
• AI framing — automatically frames active speakers for remote participants

The A30 mounts cleanly below a display or sits on a table. Its footprint is small enough that it doesn't dominate a compact space. For huddle rooms and focus spaces, it's the right tool — adding an A50 to a four-person room is unnecessary spend and actually overkill for the acoustics.

Best for: Huddle rooms, focus rooms, consultation rooms, small team spaces (2–6 seats).

The Yealink A40 — Medium Conference Rooms

The A40 sits between the A30 and A50, designed for medium meeting rooms seating six to ten people. It features:

• 133° ultra-wide camera with 5x digital zoom — covers a longer table and can zoom to focus on the active speaker
• Dual microphone array with six-metre pickup range — reaches participants at the far end of a medium table
• 20W stereo speakers — better room fill than the A30 for a larger space
• AI speaker tracking — tracks and frames the active speaker automatically

The A40 is the right choice when a room is too large for an A30's microphone range but doesn't justify the A50's price point. It's commonly used in mid-sized meeting rooms, team rooms with breakout areas, and training spaces.

Best for: Medium conference rooms, team rooms, training spaces (6–10 seats).

The Yealink A50 — Boardrooms and Large Conference Rooms

The A50 is built for serious conference rooms — boardrooms, executive meeting suites, and large presentation spaces seating ten to twenty people. Its specifications reflect the requirements of larger rooms:

• 133° ultra-wide camera with 5x zoom and AI framing — covers a full boardroom table with active speaker tracking
• Dual microphone array with eight-metre pickup range — reaches participants at the far end of a long boardroom table
• 20W stereo output — strong room fill for larger spaces
• Optional expansion microphone pods — for rooms wider than standard, or U-shaped table configurations

The A50 is also the appropriate choice when the room's purpose demands a premium visual experience — board meetings, client presentations, and all-hands sessions where the quality of the remote experience reflects on the organisation.

Best for: Boardrooms, executive suites, large conference rooms, all-hands spaces (10–20 seats).

What They All Have in Common

Regardless of which model you choose, all three A-Series bars share the same core platform:

• Run Microsoft Teams Rooms OS on dedicated hardware — no laptop dependency
• Certified by Microsoft for Teams Rooms
• Managed centrally through Microsoft Intune and Teams Admin Centre
• One-touch join for scheduled Teams meetings from the room display
• Automatic firmware and Teams app updates pushed remotely
• Native integration with Microsoft 365 calendar for room booking

How to Spec Your Rooms

When Optimyze scopes a Teams Rooms deployment for a NZ business, we work through every meeting space and map it to the right hardware. The key variables are: room dimensions, seating capacity, table shape, and the primary use case for the room. A room used primarily for internal stand-ups has different requirements from a client-facing boardroom.

We also consider the display — the A-Series bars require an HDMI-connected screen, and room size should inform whether a single or dual-display setup is appropriate. For rooms used for presentations, a second display showing the content separately from the participant video is worth the additional cost.

If you're not sure which bar fits which room, Optimyze offers a free Teams Rooms assessment — we'll walk through your meeting spaces and give you a clear recommendation before any hardware is ordered.
