How to Spec a Commercial AV System

A commercial AV system that works is boring - it turns on, everyone can hear and see, the meeting starts on time. Getting to boring takes real engineering. Here's the process we run on every commercial project, from a four-person huddle room to a full event space.

Step 1: Define How the Room Gets Used

Before a single product goes on a bid, we answer the questions that actually determine the design:

• Who's in the room, and how many? A 6-seat conference room and a 60-seat training room are different animals.
• What happens in it? Video calls, presentations, live events, digital signage - each drives different microphone, display, and audio choices.
• Who operates it? If a non-technical employee has to run it, the control system has to be idiot-proof, not feature-proof.

Nine times out of ten, a bad AV install traces back to skipping this step and buying gear first.

Step 2: Get the Audio Right First

People forgive a mediocre picture. They will not forgive not being able to hear. Audio is where commercial AV lives or dies:

• Microphone coverage sized to the room - ceiling arrays for conference spaces, distributed wireless for events, so every voice is picked up cleanly.
• Speaker layout designed for even coverage, not just "loud enough at the front."
• DSP and acoustic echo cancellation tuned so remote participants hear the room, not the HVAC and the reverb.

Step 3: Match Displays to Viewing Distance

Display size isn't about the biggest screen the budget allows - it's about the farthest seat. The rule of thumb: the closest viewer sets minimum resolution, the farthest viewer sets minimum size. We size displays (or projection, or LED video wall) so the person in the back row can read the smallest text that will ever appear on screen.

Spec the room, not the shopping list. The hardware is the last decision, not the first.

Step 4: Control and Connectivity

The system has to be usable by whoever walks in. That means a single, obvious control interface - a touch panel or a button that says "Start Meeting" - and the connectivity people actually use: wireless presentation, the right cable at the table, and native support for whatever video platform the business runs on.

Step 5: Plan for Support and Growth

Commercial AV is infrastructure. We spec systems that can be monitored, updated, and expanded - and we document them so the next change doesn't mean starting over. A cheap system that can't be serviced is the most expensive kind.

The Brookwood Take

We bring the same discipline to a two-person office as a multi-room facility: understand the use, engineer the audio, size the visuals, simplify the control, and build it to last. The result is a system nobody has to think about - which is exactly the point.
