Conference room audio is the part of a video meeting people notice only when it fails, and it fails in predictable ways: a participant at the far end of a 24-foot table who sounds distant, an echo that appears when someone opens a laptop with its own microphone active, a room where the loudspeaker is loud enough to be intelligible but so directional that half the table cannot hear it. None of those are fixed by a better camera. They are fixed by deciding, before purchase, how many microphone pickup zones the room needs, where the DSP lives, and how the audio chain connects to the meeting platform.
This guide is for integrators, IT managers, and AV designers specifying conference room audio in rooms that will run Microsoft Teams Rooms, Zoom Rooms, or a comparable platform. Shure's Microflex family and Logitech's room appliances are frequently paired in this role because the two ecosystems are designed to interoperate — mute state, LED status, and volume can be synchronized across the two without custom programming. That interoperability is genuinely useful, but it is the last decision in the process, not the first.

Where Conference Room Audio Specifications Go Wrong
The most common mis-spec is applying a small-room device to a medium or large room because the device is certified for the platform. Platform certification confirms that a device works correctly with Teams or Zoom; it says nothing about whether that device's microphone reaches the far end of your table. An all-in-one video bar with integrated beamforming microphones is genuinely excellent in a huddle space and genuinely inadequate in a 26-foot boardroom. Check the manufacturer's published pickup distance for the integrated array and compare it against the measured distance from the device to the farthest chair. If the farthest chair is beyond that figure, the room needs separate microphones and the video bar becomes a camera.
The second failure is acoustic rather than electronic. Reverberation time and background noise set the ceiling on what any microphone can achieve. A glass-walled conference room with a hard ceiling, a bare table, and an HVAC diffuser directly above the head of the table will defeat a well-specified array. Measure or at least estimate the room's reverberation and note the HVAC noise floor during a site walk. If the room is acoustically hostile, treatment is cheaper than the microphone upgrade that will be attempted after treatment is skipped.
The third failure is network readiness. Networked audio systems — Dante, AES67, and platform-specific variants — carry uncompressed audio over the same structured cabling as everything else, and they require a switch configuration that most enterprise access layers do not have by default. Confirm the PoE budget per port and across the switch, confirm QoS marking is configured for the audio VLAN, confirm the switch supports the required multicast handling, and confirm the AV devices will not be placed on a network segment with an aggressive DHCP lease or captive portal. Bring the network team into the design conversation, not the commissioning visit.
How to Match Audio Coverage to the Room
Work outward from the seats. Every other decision follows from where people sit and how far they are from the nearest microphone.
Count Pickup Zones, Not Microphones
Divide the seating area into zones each covered by one microphone element or one steerable lobe. A rectangular table seating twelve typically needs coverage across its full length, which is one or two ceiling arrays with multiple steerable lobes, or several table microphones. The number that matters is how many simultaneous talkers the system can track and how much of the table falls outside any lobe. Ask the manufacturer for the coverage pattern at your specific ceiling height, because coverage area shrinks as the array moves farther from the talkers.
Decide Ceiling Versus Table Early
Ceiling arrays keep the table clear, survive furniture rearrangement, and are the default in rooms with an accessible tile grid. Table microphones sit closer to the talker, which gives better signal-to-noise in acoustically difficult or high-ceiling rooms, at the cost of table clutter, cable penetrations, and a surface people knock. The decision rule: choose ceiling arrays when the ceiling is accessible and under roughly 12 feet; choose table microphones when the ceiling is hard-lidded, very high, or acoustically poor. Where the client cannot commit to a table layout, ceiling is the safer long-term call.
Size the DSP Before Choosing Microphones
Count microphone channels, loudspeaker zones, program audio inputs, and any assistive listening or overflow feed, then specify a DSP with headroom above that total. Confirm the DSP provides acoustic echo cancellation on the correct reference and that the AEC reference is taken from the actual far-end signal path. An echo canceller referenced to the wrong signal is the single most common cause of persistent echo complaints on otherwise well-built systems.
Networked Microphone and Speaker Systems for Conference Rooms
The Shure Microflex ecosystem is built around networked devices that share one cabling infrastructure and one management interface. On the loudspeaker side, the Shure Microflex MXN5W-C Networked Audio Speaker is a PoE-powered ceiling loudspeaker tuned for speech reproduction in conferencing rather than for program music. Its value in a specification is that it removes the amplifier and the 70V distribution run from the bill of materials entirely — power and audio arrive on the same Cat6 drop, which changes the electrical and cabling scope for the room. For conference rooms that need voice intelligibility rather than background music, that is a meaningful simplification. For rooms that also serve as event or training spaces with music playback, a conventional amplified 70V system is still the better choice.
User control is worth specifying deliberately. The Shure MXA MUTE Network Button is a PoE network mute control that gives participants a physical, unambiguous mute with visible state. In rooms where the only mute is buried in a touch panel menu, users mute the platform but not the room, or believe they are muted when they are not. A tactile mute with an LED eliminates a category of user complaint that no amount of DSP tuning addresses.
For rooms that need wireless conference microphones — flexible-layout boardrooms, council chambers, multipurpose rooms — the Shure MXCWAPT-A Access Point Receiver is the access point transceiver at the center of a Microflex Complete Wireless system. Wireless conference systems trade the cable infrastructure for a charging and battery management workflow, so confirm who owns that workflow before specifying one. A wireless system with no assigned charging routine becomes a room full of dead microphones within a quarter.
Logitech Room Appliances and Where Integrated Audio Is Sufficient
Logitech's appliance model separates compute from peripherals, which is what makes the pairing with external audio practical. The Logitech RoomMate CollabOS Video Conferencing Room Appliance provides the compute for a Teams Rooms on Android or Zoom Rooms Appliance deployment without a Windows PC in the credenza. Paired with a touch controller and either an integrated video bar or discrete camera and audio, it becomes the room's head end. Using RoomMate rather than a PC removes an operating system, an antivirus agent, and a patch cycle from the room, which is the reason large deployments increasingly standardize on appliances.
For small and huddle spaces, integrated audio is genuinely sufficient and adding external microphones is wasted budget. The Logitech Rally Bar Huddle + Tap IP for Teams Rooms on Android covers huddle and small rooms as a complete unit, and the Logitech Small Room with Tap + Rally Bar Mini for Microsoft Teams Room serves small to medium spaces. For medium rooms, the Logitech Rally Bar + Tap IP Bundle for Microsoft Teams Rooms is the standard configuration.
The decision rule between integrated and external audio is distance and acoustics, stated plainly: if every seat is within the video bar's rated microphone pickup distance and the room is acoustically unremarkable, use the integrated audio and spend the savings on the display; if any seat is beyond that distance, or the room is reverberant, or the table is long and narrow, specify external microphones and a DSP and treat the video bar as a camera and loudspeaker. Rooms that sit near the boundary should get external audio, because the failure mode of under-specifying is a permanent complaint and the cost of over-specifying is a line item.
Integration, Mute Synchronization, and Signal Flow
When Shure networked audio and Logitech room devices are deployed together, the integration work is mostly configuration rather than programming. Mute state, LED indication, and volume can be synchronized between the microphone system and the room controller so that pressing mute anywhere mutes everywhere and the indication is consistent. That matters operationally: rooms where the table mute and the touch panel mute disagree generate support tickets and, occasionally, incidents.
Document the signal flow before installation. Note where the far-end reference for echo cancellation originates, whether audio reaches the platform over USB or over the network, which device performs gain staging, and what happens when a laptop is plugged in with its own microphone active. Draw it on one page and put a copy in the rack. Five years from now the person diagnosing an echo complaint will have that page and nothing else, and it will save an afternoon.
What a Correctly Specified Conference Room Audio System Delivers
A correctly specified system produces one result above all others: nobody talks about the audio. Remote participants stop asking people to repeat themselves, the far end stops hearing the room's HVAC, and meetings run without the first three minutes spent on troubleshooting. That translates directly into recovered meeting time across every room in the portfolio.
Operationally, networked audio built on PoE and structured cabling reduces the electrical scope, eliminates amplifier racks in rooms that do not need them, and puts every device on a management platform that reports firmware state and health without a site visit. Standardizing on one microphone and DSP family across room sizes means technicians learn one configuration tool, spares are shared inventory, and a failed ceiling array is a swap rather than a redesign. And because these systems are network-managed, capacity changes — adding a microphone zone when a wall moves, re-tuning coverage after a furniture change — are configuration work rather than construction.
Specifying Your Conference Room Audio Deployment
Before requesting pricing, confirm:
- Measured distance from the intended microphone position to the farthest seat, compared against the device's rated pickup distance.
- Ceiling height and construction, which decides ceiling arrays versus table microphones.
- Room acoustics: reverberation, hard surfaces, and the HVAC noise floor measured during normal operation.
- DSP channel count with headroom, and the correct acoustic echo cancellation reference.
- Network readiness: PoE budget per port and switch-wide, QoS on the audio VLAN, and multicast handling.
- Meeting platform and whether the room runs on an appliance or a PC, since that determines the audio connection path.
