Conference Room Speaker Systems: Professional Audio for Every Meeting Space
Deploy crystal-clear conference room audio with professional speaker systems, ceiling microphone arrays, and DSP processing designed for hybrid meetings.
Why Audio Is the Most Critical Element in Your Conference Room
A conference room speaker system is the backbone of productive meetings. Research consistently shows that poor audio quality causes more frustration and lost productivity than any other factor in conference calls, including poor video. When participants cannot hear clearly or struggle with echo, background noise, or uneven volume levels, meetings become exercises in repetition rather than collaboration. According to a 2024 Frost & Sullivan study, 78% of remote meeting participants cite audio quality as their top concern, far exceeding video resolution or screen sharing capability.
A properly engineered conference room speaker system encompasses far more than a pair of ceiling speakers. It is an integrated audio ecosystem that includes microphone arrays for voice capture, digital signal processing (DSP) for echo cancellation and noise reduction, amplification for clear output, and acoustic treatment to manage the physical room environment. Each of these components must work together, and a weakness in any single element degrades the entire experience. A $5,000 ceiling microphone array will underperform in a room with excessive reverberation, just as a premium DSP processor cannot compensate for poorly placed speakers.
Whether you are building a new conference room, upgrading an outdated system, or troubleshooting persistent audio problems, understanding these components and how they interact is essential. Petronella Technology Group designs, installs, and manages conference room audio solutions for businesses across the Triangle and beyond. Our conference room solutions cover the full technology stack from AV hardware to network infrastructure, so your meeting spaces perform reliably from day one.
This guide covers everything you need to know about conference room audio: the components that make up a professional system, brand and product comparisons, room sizing guidelines, ceiling microphone deep dives, DSP processing, acoustic treatment, and integration with platforms like Zoom and Microsoft Teams. By the end, you will have the knowledge to make informed decisions about your conference room speaker system investment.
Conference Room Audio System Components
A professional conference room audio system is built from eight core components. Each plays a distinct role, and understanding what each does helps you prioritize your budget and avoid common mistakes that lead to subpar audio performance.
Ceiling Microphone Arrays
Beamforming microphone arrays mounted flush in the ceiling capture voices from anywhere in the room without table clutter. Products like the Shure MXA920 and Biamp Parlé TCM-XA use multiple capsules and digital beam steering to focus on active speakers while rejecting noise from HVAC systems and projector fans. Coverage ranges from 400 to 1,000 square feet per unit depending on ceiling height.
Tabletop Microphones
Boundary microphones and tabletop arrays sit on or near the conference table for focused voice pickup. Options include the Shure MXA310, Biamp Parlé TTM-X, and Poly Studio microphone pods. These work well in smaller rooms or as supplements to ceiling arrays in large boardrooms where participants may be far from overhead mics.
Ceiling Speakers
In-ceiling speakers distribute audio evenly across the room so every participant hears remote attendees at the same volume. The Shure MXN5-C, Biamp Desono C-IC6, and QSC AD-C series are popular choices. Proper speaker placement avoids hot spots near the table and dead zones at the room perimeter. Most medium rooms need four to six ceiling speakers for even coverage.
Soundbars
All-in-one soundbars combine speakers, microphones, and sometimes cameras in a single unit mounted below the display. The Poly Studio X70, Jabra PanaCast 50, and Yamaha CS-800 are common in huddle rooms and small conference rooms. Soundbars simplify installation but sacrifice the audio separation and coverage of distributed ceiling systems.
DSP Processors
Digital Signal Processors are the brains of any professional conference room audio system. They handle acoustic echo cancellation (AEC), noise reduction, automatic gain control (AGC), equalization, and beam steering. The Biamp Tesira, QSC Q-SYS Core, Shure IntelliMix P300, and Crestron DSP-1283 are leading options. Without dedicated DSP, even premium microphones and speakers will produce poor conference call audio.
Amplifiers
Power amplifiers drive ceiling speakers and wall-mounted speakers. Many DSP processors include built-in amplification for smaller rooms, but larger spaces with six or more speakers typically require standalone amplifiers. The Biamp Tesira AMP-450BP and QSC CX-Q series provide clean power delivery with network management capabilities.
Acoustic Panels
Sound-absorbing panels mounted on walls and ceilings reduce reverberation (echo) so that both in-room participants and remote callers hear clear speech. An untreated conference room with hard parallel walls, glass, and a flat ceiling can have reverberation times exceeding 1.5 seconds, making speech intelligibility difficult. Strategic placement of panels with NRC ratings of 0.80 or higher transforms the acoustic environment.
Acoustic Echo Cancellation (AEC)
AEC is a DSP algorithm that prevents the far-end audio from speakers being picked up by microphones and sent back to remote participants as echo. Modern AEC handles full-duplex conversations where both sides speak simultaneously. This function runs inside the DSP processor, but its performance depends heavily on speaker and microphone placement, room acoustics, and proper system calibration after installation.

Conference Room Speaker System Sizing Guide by Room Type
One of the most common mistakes in conference room audio is under-specifying or over-specifying equipment for the room size. A boardroom-grade system in a huddle room wastes budget, while a consumer speakerphone in a 20-person conference room creates a frustrating experience for remote participants. Use the table below to match your room dimensions to the appropriate audio components.
| Room Type | Area | Seats | Microphone Type | Mic Count | Speaker Type | Speaker Count | DSP Required | Approximate Cost |
|---|---|---|---|---|---|---|---|---|
| Huddle Room | Under 150 sq ft | 2-4 | Soundbar or USB speakerphone | 1 | Built-in soundbar | 1 | No (built-in) | $500 - $2,500 |
| Small Conference | 150 - 300 sq ft | 4-8 | Tabletop array or video bar | 1 | Video bar or 2 ceiling speakers | 1-2 | Recommended | $2,500 - $8,000 |
| Medium Conference | 300 - 600 sq ft | 8-14 | Ceiling microphone array | 1 | Ceiling speakers | 4 | Yes | $8,000 - $18,000 |
| Large Conference | 600 - 1,200 sq ft | 14-24 | Ceiling microphone array(s) | 1-2 | Ceiling speakers | 6-8 | Yes | $15,000 - $35,000 |
| Boardroom | 1,200+ sq ft | 20-40+ | Multiple ceiling arrays + table mics | 2-4 | Ceiling speakers + subwoofer | 8-12 | Yes (dedicated rack) | $30,000 - $80,000+ |
These cost ranges include equipment, installation, cabling, DSP programming, and commissioning. They do not include acoustic treatment, which typically adds $2,000 to $10,000 depending on room size and existing conditions. A room with floor-to-ceiling glass walls, for example, requires significantly more acoustic treatment than a room with standard drywall construction.
Ceiling height is another critical factor. Standard 9-foot ceilings work well with most ceiling microphone arrays. Rooms with ceilings above 12 feet may need microphones with extended pickup ranges like the Biamp Parlé TCM-XA, which supports ceilings up to 20 feet. Open-plan spaces with exposed ceilings above 14 feet often require tabletop microphone supplements to ensure consistent voice pickup.
Ceiling Microphone Arrays: The Standard for Modern Conference Audio
Ceiling microphone arrays have become the default choice for professional conference rooms from medium-sized spaces upward. By mounting microphones in the ceiling rather than on the table, you eliminate cable clutter, free up table space for laptops and documents, and provide consistent voice pickup regardless of where participants sit. More importantly, ceiling arrays with beamforming technology actively track and focus on the person speaking, rejecting noise from HVAC systems, projectors, and side conversations.
How Beamforming Works
A beamforming microphone array contains multiple capsules (typically 8 to 28 depending on the model) arranged in a specific pattern. The DSP compares the arrival time and phase of sound at each capsule to determine the direction of the sound source. It then creates a virtual directional pickup pattern, called a beam or lobe, aimed at the active speaker. Modern arrays can maintain multiple simultaneous beams, allowing them to capture audio from several speakers at different locations in the room.
There are two approaches to beamforming: fixed beams (configured during installation to cover specific zones) and automatic beams (which dynamically track speakers as they move). Shure calls their automatic approach "Autofocus," while Biamp uses "Beamtracking." Both produce excellent results, but automatic beamforming is generally preferred because it adapts to different meeting layouts and requires less tuning after installation.
Leading Ceiling Microphone Array Models
Shure MXA920: The MXA920 is Shure's flagship ceiling array microphone. It features up to 8 configurable lobes with automatic coverage mode, a built-in LED ring for mute indication, Dante and AES67 network audio output, and integration with Shure IntelliMix DSP. The MXA920 fits in a standard 24-inch ceiling tile grid and covers rooms up to approximately 30 x 30 feet with a single unit. It supports ceiling heights from 8 to 13 feet. Street price is approximately $3,200 to $4,000.
Biamp Parlé TCM-XA: The Biamp Parlé TCM-XA is purpose-built to pair with Biamp Tesira DSP processors. It uses Beamtracking technology with automatic zone coverage, supports ceiling heights up to 20 feet (industry leading), and outputs audio over Dante. The TCM-XA is slightly larger than a standard ceiling tile at approximately 24 x 24 inches. Biamp's advantage is tight integration with the Tesira DSP platform, where microphone configuration, AEC, and room tuning are managed from a single software interface. Street price is approximately $2,800 to $3,500.
Sennheiser TeamConnect Ceiling 2: The TeamConnect Ceiling 2 (TCC2) packs 28 MEMS microphone capsules into a compact form factor. Its automatic beamforming tracks up to five speakers simultaneously, and it outputs audio over Dante. The TCC2 is particularly strong in rooms with higher ceilings and supports heights up to 16 feet. A unique feature is its patented "TruVoicelift" mode that amplifies quiet speakers in the room through ceiling speakers in real time. Street price is approximately $3,000 to $4,000.
ClearOne BMA 360: The BMA 360 is a budget-friendly beamforming array with built-in AEC processing, which means it can work without an external DSP in simpler installations. It supports Dante output and covers rooms up to approximately 25 x 25 feet. The built-in AEC is a genuine advantage for small to medium rooms where budget does not support a separate DSP processor. Street price is approximately $1,800 to $2,500.
Why Ceiling Mics Are Superior to Table Mics for Most Rooms
Table microphones require participants to sit within a defined radius, create cable management challenges, pick up table noise like tapping and paper shuffling, and can be accidentally muted or unplugged. Ceiling arrays eliminate all of these issues. The only scenarios where table microphones are clearly better are very small huddle rooms (where a single tabletop device suffices) and exceptionally high-ceiling spaces above 20 feet where ceiling arrays lose pickup sensitivity.

If the microphones are the ears and the speakers are the voice of your conference room, the DSP processor is the brain. Digital Signal Processing handles the real-time manipulation of audio signals to make conference calls clear and natural. Without proper DSP, even a room with premium microphones and speakers will suffer from echo, feedback, uneven volume, and noise interference.
What Conference Room DSP Does
Acoustic Echo Cancellation (AEC): When far-end audio plays through speakers, those speakers are picked up by the room microphones. Without AEC, remote participants hear their own voice played back with a delay, creating a distracting and sometimes unusable echo. AEC algorithms continuously model the acoustic relationship between speakers and microphones, then subtract the speaker signal from the microphone input in real time. Modern AEC supports full-duplex conversation, meaning both sides can talk simultaneously without the system suppressing either party.
Noise Reduction: Conference rooms contain constant background noise from HVAC systems, projector fans, computers, and street traffic. DSP noise reduction algorithms distinguish between human speech patterns and steady-state noise, suppressing the noise while preserving voice clarity. Advanced systems like Shure IntelliMix can reduce HVAC noise by up to 20 dB without noticeable artifacts on the speech signal.
Automatic Gain Control (AGC): Participants speak at different volumes, and a person sitting six feet from a microphone produces a weaker signal than someone directly below it. AGC continuously adjusts microphone levels so all speakers are transmitted at a consistent volume to remote participants. This prevents the frustrating experience of straining to hear a quiet speaker followed by being blasted by a loud one.
Beam Steering and Management: For beamforming microphone arrays, the DSP handles the complex mathematics of calculating beam positions, tracking active speakers, and mixing beams. This processing runs thousands of times per second with latency under 5 milliseconds to avoid audible delay.
Room Equalization: Every room has a unique frequency response based on its dimensions, construction materials, and furnishings. DSP equalization adjusts the speaker output to compensate for room resonances and absorption patterns, producing flatter, more natural-sounding audio. Professional installers measure the room response with calibration microphones and program custom EQ curves into the DSP.
DSP Platform Comparison
Biamp Tesira: The Tesira platform is the most widely deployed conference room DSP in the enterprise market. Available in multiple hardware configurations (TesiraFORTÉ, TesiraLUX, Tesira SERVER-IO), it handles everything from a single room to a campus-wide deployment with hundreds of endpoints. Programming is done through Biamp's drag-and-drop software interface. Tesira supports Dante networked audio natively and integrates directly with Biamp Parlé microphones for simplified setup. Tesira is the strongest choice for organizations that want a unified AV platform across multiple rooms.
QSC Q-SYS: Q-SYS takes a software-defined approach to DSP, running on QSC Core processors. Its key differentiator is a fully programmable visual programming environment that allows integrators to build complex control logic alongside audio processing. Q-SYS also includes video routing, control system functionality, and room scheduling in a single platform. For large organizations managing many conference rooms, Q-SYS provides centralized monitoring and management through Q-SYS Reflect.
Shure IntelliMix: Shure offers two IntelliMix options. The IntelliMix P300 is a hardware DSP processor designed specifically for conference rooms. The IntelliMix Room software runs on a standard Windows PC or Mac, eliminating dedicated DSP hardware entirely. Both include Shure's proprietary AEC, noise reduction, and AGC algorithms, optimized to work with Shure MXA microphones. IntelliMix Room is particularly cost-effective for organizations already deploying Shure microphones in Zoom or Teams rooms with a dedicated compute device.
Crestron DSP: Crestron's DSP-1283 processor integrates natively with Crestron control systems and touch panels. It supports AEC, noise cancellation, and standard audio processing. The primary advantage is single-vendor integration when the entire room control, display management, and audio processing runs on Crestron. The trade-off is that Crestron DSP is generally considered less advanced in raw audio processing compared to Biamp Tesira or QSC Q-SYS.
Why Dedicated DSP Matters
Some all-in-one devices and UC platforms include built-in DSP features, and organizations sometimes ask whether dedicated DSP hardware is necessary. For huddle rooms and small conference rooms with a single soundbar, built-in processing is often adequate. But for medium rooms and above, dedicated DSP provides dramatically better echo cancellation, finer-grained control over microphone processing, the ability to manage complex multi-microphone and multi-speaker configurations, and centralized management across a building or campus. Dedicated DSP is not a luxury for rooms with more than eight seats; it is a requirement for reliable conference call audio.
Acoustic Treatment Basics for Conference Rooms
The best microphones and DSP processors in the world cannot fully compensate for a room with poor acoustics. Sound bounces off hard, reflective surfaces like glass walls, whiteboards, concrete, and flat drywall ceilings. These reflections arrive at the microphone milliseconds after the direct voice signal, creating a smeared, reverberant sound that degrades both in-room intelligibility and the audio sent to remote participants. Acoustic treatment addresses this at the source.
Understanding RT60
RT60 is the standard measurement of room reverberation, defined as the time in seconds for sound to decay by 60 decibels after the source stops. An untreated conference room with hard parallel walls and a flat ceiling might have an RT60 of 1.2 to 2.0 seconds. The target for conference room speech intelligibility is an RT60 of 0.4 to 0.6 seconds. Achieving this target typically requires adding absorptive materials to 20% to 40% of the room's reflective surfaces.
RT60 can be measured with a calibration microphone and analysis software like Room EQ Wizard (REW), or with smartphone apps that provide rough approximations. Professional acousticians use standardized measurement protocols (ASTM C423) for precise results. If your RT60 exceeds 0.8 seconds, acoustic treatment should be a priority before investing in premium audio equipment.
Absorption Panels
Acoustic absorption panels are the most common treatment for conference rooms. They are typically constructed from fiberglass, mineral wool, or open-cell foam wrapped in acoustically transparent fabric. Key specifications include the Noise Reduction Coefficient (NRC), which ranges from 0 (perfectly reflective) to 1.0 (perfectly absorptive). For conference room treatment, panels with NRC ratings of 0.80 or higher are recommended. Standard panel sizes are 2 x 4 feet or 2 x 2 feet, with thicknesses of 1 inch (NRC around 0.75) to 2 inches (NRC around 0.95).
Placement Guidelines
Effective acoustic treatment follows a few core principles. First, treat the first reflection points: the wall areas where sound from the speaker locations bounces directly to the listener positions. In a conference room, this means panels on the walls at seated ear height (approximately 3 to 5 feet from the floor) and on the ceiling above the conference table. Second, break up parallel surfaces. Two large parallel walls create flutter echo, a rapid series of reflections that smears speech. Treating even one wall of a parallel pair eliminates flutter echo. Third, address the ceiling, especially in rooms with hard flat ceilings below 10 feet. Ceiling-mounted acoustic clouds or baffles are highly effective.
How Acoustic Treatment Interacts with DSP
Acoustic treatment and DSP are complementary, not substitutes. Acoustic treatment reduces the amount of reverberation and noise that reaches the microphone in the first place, making the DSP processor's job easier. AEC algorithms perform better in treated rooms because the echo pattern is simpler and more predictable. Noise reduction algorithms produce fewer artifacts because the signal-to-noise ratio is higher. In practice, investing $3,000 in acoustic panels for a medium conference room can improve perceived audio quality more than spending $3,000 on a DSP upgrade, because the panels address the root cause of the problem.
When to Bring in an Acoustician
For standard conference rooms with drywall walls and dropped ceilings, a knowledgeable AV integrator can handle acoustic treatment without a dedicated acoustician. However, if your room has extensive glass (more than two glass walls), unusual geometry (non-rectangular shapes, very high ceilings, open mezzanines), or is adjacent to high-noise environments (manufacturing floors, server rooms), a professional acoustician can provide targeted recommendations that avoid over-treatment or under-treatment. Petronella Technology Group works with acoustic consultants when projects require specialized expertise.
Integrating Conference Room Audio with Zoom, Teams, and Webex
A conference room speaker system only delivers value when it connects smoothly to the video conferencing platforms your organization uses daily. The bridge between professional AV audio and unified communications (UC) platforms like Zoom, Microsoft Teams, and Cisco Webex requires careful attention to signal routing, device certification, and network configuration.
USB Audio Output for UC Platforms
The simplest integration method is USB audio. Many DSP processors include a USB-B port that presents the processed microphone audio and accepts far-end speaker audio as a standard USB audio device. The room's compute device (a Zoom Room appliance, Teams Room PC, or laptop) sees the DSP as a USB microphone and speaker. The Shure IntelliMix P300, Biamp TesiraFORTÉ VT, and QSC Q-SYS USB Bridge all support this approach. USB integration is reliable, simple to troubleshoot, and works with any UC platform without drivers.
For Zoom Rooms, certified audio devices from Shure, Biamp, and QSC appear in the Zoom Room controller's device list and enable advanced features like room-level echo cancellation coordination. Similarly, Microsoft Teams Rooms support certified USB audio peripherals with automatic device detection and health monitoring through the Teams Admin Center.
Dante Audio Networking
Dante (Digital Audio via Network Technology) from Audinate has become the de facto standard for networked audio in professional AV installations. Instead of running analog cables from microphones to the DSP and from the DSP to amplifiers, Dante carries hundreds of audio channels over standard Ethernet cables. A single Cat6 cable can replace dozens of analog audio runs, dramatically simplifying installation and reducing cable costs.
All major conference room audio brands support Dante: Shure MXA microphones and MXN speakers are Dante-native, Biamp Tesira and Parlé use Dante throughout, QSC Q-SYS supports Dante bridging, and Sennheiser TeamConnect Ceiling outputs Dante audio. This interoperability means you can mix brands on the same Dante network when needed.
AES67 and AVB
AES67 is an open standard for networked audio that provides interoperability between different networked audio protocols. Dante devices support AES67 mode, allowing them to communicate with non-Dante AES67 devices from other ecosystems. AVB (Audio Video Bridging) is an IEEE standard that provides deterministic low-latency audio transport and is used by some manufacturers including Apple (in their Pro Audio ecosystem). For most conference room installations, Dante with AES67 compatibility provides the broadest device support.
Network Audio: Dante and AES67 for Conference Rooms
Networked audio is replacing traditional analog audio cable runs in professional conference room installations. Understanding the basics of Dante and AES67 helps you plan the network infrastructure needed to support a modern conference room speaker system.
What Networked Audio Is and Why It Replaces Analog
In a traditional conference room audio installation, each microphone connects to the DSP via a dedicated analog or digital cable, and each speaker connects to the amplifier via a dedicated speaker wire. A medium conference room might have 10 to 15 individual cable runs from the ceiling to an AV rack. Networked audio replaces these individual runs with standard Ethernet connections. Each Dante-enabled device (microphone, speaker, DSP) connects to a network switch, and audio channels are routed in software. A single Cat6 cable supports up to 512 audio channels at 48kHz/24-bit resolution with sub-millisecond latency.
The practical benefits are substantial. Installation is faster and less expensive because Ethernet cable is cheaper than specialty audio cable and easier to terminate. Changes to audio routing (reassigning a microphone to a different DSP input, for example) happen in software without physical rewiring. Troubleshooting is simpler because Dante devices report their status, audio levels, and network health through monitoring software. And scalability is straightforward: adding a new microphone or speaker just means adding another Ethernet drop.
Dante vs AES67
Dante is a proprietary protocol from Audinate that has become the market standard for professional AV audio networking. It runs on standard IP networks, supports automatic device discovery, and provides management tools (Dante Controller) for routing and monitoring. AES67 is an open standard published by the Audio Engineering Society that defines interoperability requirements for IP-based audio. Dante devices can operate in AES67 compatibility mode, and most modern Dante devices support this by default. The practical difference: if all your devices are Dante, use Dante mode for simplicity. If you need to integrate devices from different audio networking ecosystems, enable AES67 mode.
Network Switch Requirements
Dante audio runs on standard Gigabit Ethernet switches, but the switches must meet specific requirements. They must support IGMP snooping to prevent multicast audio traffic from flooding all switch ports. They must support QoS (Quality of Service) with DSCP marking to prioritize audio packets over general network data. Energy Efficient Ethernet (EEE, or "Green Ethernet") must be disabled on Dante ports because EEE's micro-sleep behavior introduces unacceptable latency. Managed switches from Cisco, HP/Aruba, Netgear, and others are all suitable. Audinate maintains a list of validated switches on their website.
Multicast Setup and Clock Synchronization
Dante uses multicast for audio distribution when one source feeds multiple destinations. Proper IGMP snooping configuration on all switches in the path is essential to prevent multicast storms that can degrade network performance. For installations spanning multiple switches, PTP (Precision Time Protocol, IEEE 1588) provides clock synchronization to keep all devices sample-aligned. Dante handles PTP automatically through its "Preferred Master" clock selection, but the network must allow PTP traffic to pass between switches without being filtered or rate-limited.
If your organization uses VLANs, Dante traffic should run on a dedicated VLAN or on the same VLAN as other AV equipment. Separating AV traffic from general office data traffic is a best practice that simplifies QoS configuration and troubleshooting. Our managed IT services team handles network design and VLAN configuration as part of conference room deployments.
Who Needs a Professional Conference Room Speaker System?
Professional conference room audio is not limited to large enterprises.

What is the best conference room speaker system for a medium-sized room?
For a medium conference room (300 to 600 square feet, 8 to 14 seats), the most reliable setup is a ceiling microphone array paired with four in-ceiling speakers and a dedicated DSP processor. Specific recommendations include the Shure MXA920 microphone with IntelliMix P300 DSP and four MXN5-C ceiling speakers, or the Biamp Parlé TCM-XA with a Tesira DSP and Desono ceiling speakers. The Yamaha ADECIA system is an excellent turnkey alternative that auto-configures many of these components. Budget approximately $8,000 to $18,000 including installation and programming.
Should I choose ceiling microphones or table microphones?
Ceiling microphones are the better choice for most conference rooms from small (6+ seats) to boardroom size. They eliminate table clutter, provide consistent pickup regardless of seating position, and avoid picking up table tapping and paper rustling. Table microphones are appropriate for huddle rooms (under 6 seats) where a single tabletop device covers the entire space, or as supplements in very large boardrooms with ceilings above 20 feet where ceiling arrays lose sensitivity. If your ceiling is between 8 and 14 feet and the room seats more than 6, ceiling microphones are almost always the right answer.
How much does a conference room speaker system cost?
Costs range widely based on room size and equipment tier. A huddle room with a quality soundbar runs $500 to $2,500. A small conference room with a video bar or distributed system costs $2,500 to $8,000. A medium conference room with a ceiling microphone array, DSP, and ceiling speakers runs $8,000 to $18,000. Large conference rooms cost $15,000 to $35,000, and executive boardrooms with multiple microphone arrays, dedicated DSP racks, and acoustic treatment can range from $30,000 to $80,000 or more. These ranges include equipment, installation, cabling, programming, and commissioning but not acoustic treatment, which adds $2,000 to $10,000.
Do I need a DSP processor, or is built-in processing enough?
For huddle rooms and small conference rooms with a single all-in-one device (like a Poly Studio X50 or Jabra PanaCast 50), built-in processing is adequate. For medium rooms and above with ceiling microphone arrays and distributed ceiling speakers, a dedicated DSP processor is essential. Dedicated DSP provides superior echo cancellation, noise reduction, automatic gain control, and the ability to manage complex multi-microphone configurations. Trying to run a medium or large conference room without dedicated DSP will result in echo complaints, inconsistent volume, and poor far-end audio quality.
Does my conference room need acoustic treatment?
If your conference room has hard parallel walls, a flat hard ceiling, large glass surfaces, or a tiled floor, the answer is almost certainly yes. You can perform a simple test: clap your hands in the center of the room and listen. If you hear a noticeable echo or ringing that lasts more than half a second, acoustic treatment will significantly improve your audio quality. The target reverberation time (RT60) for a conference room is 0.4 to 0.6 seconds. Acoustic treatment typically costs $2,000 to $10,000 depending on room size and the extent of reflective surfaces, and it is one of the highest-impact investments you can make for conference room audio.
What is Dante audio networking, and do I need it?
Dante is a protocol that carries professional audio over standard Ethernet networks. Instead of running dedicated analog cables from each microphone and speaker to a central processor, Dante sends audio as data packets over Cat6 Ethernet cables. This simplifies installation, reduces cable costs, and allows software-based audio routing. You benefit from Dante if your room uses distributed ceiling microphones and speakers (rather than a single all-in-one soundbar), if you want network-based monitoring and management of audio devices, or if you plan to expand your AV infrastructure over time. Most professional conference room equipment from Shure, Biamp, QSC, and Sennheiser supports Dante natively.
What maintenance does a conference room audio system require?
Professional conference room audio systems require minimal ongoing maintenance. DSP firmware should be updated annually or when security patches are released. Ceiling microphones should be inspected for dust accumulation every six months and cleaned with compressed air if needed. Speaker grilles should be vacuumed during routine room cleaning. Most importantly, the DSP configuration should be reviewed and re-calibrated if the room layout changes significantly (furniture moved, walls added or removed, significant changes to the number of participants). Petronella Technology Group offers ongoing support and monitoring through our managed IT services to keep conference room systems performing optimally.
How do I determine the right system for my room size?
Start by measuring your room's square footage and counting the maximum number of seats. Huddle rooms (under 150 sq ft, 2 to 4 seats) need only a soundbar or speakerphone. Small rooms (150 to 300 sq ft, 4 to 8 seats) work well with a quality video bar or a simple tabletop microphone with two ceiling speakers. Medium rooms (300 to 600 sq ft, 8 to 14 seats) should use a ceiling microphone array with four ceiling speakers and a DSP processor. Large rooms (600 to 1,200 sq ft, 14 to 24 seats) need one or two ceiling microphone arrays with six to eight speakers and dedicated DSP. Boardrooms above 1,200 sq ft require multiple arrays, extensive speakers, a dedicated DSP rack, and often acoustic treatment.
