AV Transparency Project
Lessons From AI

Upgrading an 8-year-old audio-visual system to support modern Zoom Rooms and a 3-way room divisible space requires shifting from legacy analog or basic digital hardware to a flexible, network-based solution (AV-over-IP). Since your current system is failing and outdated, a full or near-full replacement will be much more reliable than trying to patch old components.

Here is the step-by-step roadmap to successfully design and implement your new system:

1. Define Your Room Combining Logic

Because you need to split the 5,000 sq ft venue into 3 separate closed spaces, your system must be able to change configurations at the touch of a button. You need to map out how the AV should behave when walls are open vs. closed:

• Independent Mode (Walls Closed): Three separate meetings happening simultaneously. Room A, Room B, and Room C must each use their own local microphones, speakers, wireless presentations, and Zoom sessions without audio bleeding or cross-talk.

• Combined Mode (Walls Open): One massive meeting. A single presenter's microphone and laptop presentation must seamlessly broadcast across all multiple display projectors and speakers throughout the entire 5,000 sq ft space.

2. Choose Your Zoom Architecture

For divisible spaces, you generally have two routes for video conferencing:

• Zoom Rooms (Recommended): A dedicated, permanent computer (Mac or PC) running the Zoom Room software, controlled by tabletop iPads or touch panels. It handles complex multi-camera and multi-microphone matrix routing seamlessly through a digital signal processor (DSP).

• BYOD (Bring Your Own Device): Users plug a USB cable into their own laptops to take over the room's cameras and mics. While cheaper, it is much harder to manage across 3 divisible spaces.

3. Inventory and Assess Existing Hardware

While most of your 8-year-old gear is likely obsolete, you might be able to save money by reusing specific infrastructure. Evaluate:

• Cabling: Are the existing cables Cat6, or are they older Cat5e / analog VGA? (Keep Cat6; replace the rest).

• Display/Projectors: Are the projectors still bright, and do they accept HDMI/digital signals? If they are laser-based, they might have life left. If they are lamp-based, it is time to replace them with commercial displays or modern laser projectors.

• Loudspeakers: Passive ceiling speakers rarely go bad. If they are zoned correctly, you can likely keep them and just replace the amplifiers driving them.

4. Core System Components to Upgrade

To achieve your goals, your new system will rely on these modern components to fulfill their roles in your divisible space:

• Networked Audio DSP: The "brain" (e.g., Biamp Tesira, Q-SYS). It uses wall-sensor logic to automatically route microphones and ceiling speakers based on whether your dividing walls are open or closed.

• AV-over-IP / Matrix Switcher: Routes video from any input (laptops, Zoom PCs) to any combination of your projectors over standard network cables.

• Ceiling Array Microphones: Instead of passing around wireless mics, modern beamforming ceiling mics (e.g., Shure MXA920) automatically track voices in a specific zone and ignore noise from adjacent rooms.

• Control System: A centralized system (e.g., Crestron, Extron, Q-SYS) paired with touch panels. Staff can press a single button ("Combine All" or "Split Rooms") to instantly reconfigure all audio, video, and Zoom settings.

5. Hire a Commercial AV Integrator

Do not attempt a divisible Zoom space as a DIY project. The programming required for audio echo cancellation (AEC) and wall-switching logic is highly specialized. Request quotes from commercial AV integration firms (look for AVIXA CTS-certified professionals).

• Ask them for examples of divisible room configurations they have programmed in the past.

If you would like to map out a rough budget or scope of work before speaking to an integrator, let me know:

• What are the exact dimensions or layout of the 3 rooms? (Are they equal sizes?)

• Do you prefer ceiling-mounted microphones or traditional table/handheld mics?

• Are the dividing walls motorized partitions with built-in sensors, or are they manual air-walls?

To transition your 5,000 square foot meeting venue into a modern, flexible, and reliable space with 3-room divisible capabilities and seamless Zoom integration, you need a systematic approach that balances upgrading reusable assets with replacing obsolete tech.

I've noted that your venue is primarily used for meetings, and given that an 8-year-old system predates the modern standard for unified communications (like Zoom Rooms), a hybrid approach of targeted troubleshooting and modular replacement will be your most cost-effective path forward.

Step 1: Conduct a Comprehensive Inventory & Triage

Before buying new gear, determine what components of your current system still have life left in them.

• Displays & Projectors: Check the brightness (lumens), resolution, and inputs of your existing projectors. If they are 1080p or 4K and accept HDMI, they can likely be reused. If they use outdated VGA connections or the lamps are dimming, plan to replace them with commercial-grade laser projectors or large-format LED displays.

• Microphones & Speakers: Professional analog microphones, ceiling speakers, and amplifiers often last decades. If your speakers sound clean, they can be kept and rewired into a new audio matrix.

• Cabling: Test the existing cable infrastructure. Category cabling (Cat6) can often be reused for modern networked audio/video, whereas old analog video cables should be decommissioned.

Step 2: Design for the 3-Room Divisible Logic

A divisible space requires an intelligent backbone that can dynamically route audio and video based on whether the movable walls are open or closed.

• The Smart Backbone (DSP): You will need a digital signal processor (DSP) featuring automixing and room-combiner logic. When partitions are closed, the DSP isolates the microphones and speakers to their respective rooms. When walls open, it instantly links them.

• Wall Partition Sensors: Install physical magnetic track sensors or simple wall-mounted button panels so the AV system automatically knows when a room is divided or opened.

• Video Routing: A modular HDMI matrix switcher or an AV-over-IP (Audio-Video over Internet Protocol) system will allow any laptop plugged into Room A to display on the screens in Rooms B and C, or keep them entirely independent.

Step 3: Integrate Native Zoom Room Capabilities

Since the system is 8 years old, it likely relies on a user plugging in a laptop via USB/HDMI to run a meeting (BYOD). Upgrading to a dedicated Zoom Room workflow vastly improves user experience.

• Central Compute & Controllers: Deploy a dedicated micro-PC (like a Mac Mini or Intel NUC) running Zoom Rooms software, paired with a tabletop touch controller in each of the three zones.

• Networked Audio: Utilize a DSP that supports USB audio bridging or networked audio protocols (like Dante). This allows the central Zoom computer to cleanly "see" all the microphones and speakers across the entire 5,000 sq ft space as a single, unified audio device.

• PTZ Cameras: Install a Pan-Tilt-Zoom (PTZ) camera in each of the three zones, routed back to the video system so Zoom participants can clearly see the presenter regardless of how the room is configured.

Step 4: Map Out a Phased Budget & Sourcing Strategy

To keep this upgrade cost-effective, categorize your purchases into what must be replaced immediately versus what can wait:

• High Priority (Audio DSP & Matrix Switcher): Replace. Buy a modern networked DSP (e.g., Q-SYS or Biamp) to handle the 3-room logic. This is non-negotiable.

• High Priority (Zoom Compute & Touch Panels): Replace. Install dedicated micro-PCs and standard PoE touch screens for seamless meeting control.

• Medium Priority (Microphones & Cameras): Upgrade/Reuse. Reuse existing wireless mics if they comply with modern FCC frequency laws. Buy cost-effective USB/HDMI PTZ cameras.

• Low Priority (Projectors & Speakers): Reuse. Keep existing ceiling speakers. Only replace projectors if they are failing or too dim for daytime meetings.

Step 5: Consult a Local Commercial AV Integrator

Because divisible spaces require advanced programming for the audio and video routing matrices, DIY installation can lead to long-term frustration. Hire a licensed commercial AV integrator to perform a site survey, handle the programming of the DSP, and certify that your network switches can handle the Zoom bandwidth traffic.

To help drill down into a more specific blueprint, could you tell me:

• What is your estimated budget range for this project?

• Do you know the exact brand and model of your current audio mixer or matrix switcher?

• Are the current movable walls tracked accordion walls (where we can install automatic sensors) or manual dividers?
