01
Room requirements
Capture room dimensions, seating, display positions, camera views, table inputs, speaker coverage, and rack location.
AV system guide
How to build an AV system that can actually be quoted and installed.
A useful AV design starts with room intent, then ties every source, processor, endpoint, cable, control path, and rack decision back to that intent.
02
Signal architecture
Choose direct wiring, HDBaseT, AVoIP, matrix/switcher, codec, soft codec, DSP, and control strategy.
03
Engineering output
Generate a riser, BOM, cable schedule, warnings, and notes that expose assumptions before the job is sold.
Start with room intent
A huddle room, training room, boardroom, divisible space, and venue do not use the same architecture. Use case determines display count, camera strategy, microphone type, speaker coverage, and control complexity.
- Define local presentation, remote conferencing, recording, streaming, paging, or live reinforcement needs.
- Set the rack location early because it changes extender and cabling requirements.
- Separate what is user-facing from what is rack-mounted or field-mounted.
Build the signal path before the BOM
The BOM should follow the topology, not the other way around. Draw the sources, switchers, processors, distribution, outputs, network, and control paths before choosing accessories.
- Sources include laptops, room PCs, cameras, media players, and wireless presentation.
- Processing includes switchers, codecs, DSPs, matrices, and control processors.
- Outputs include displays, speakers, confidence monitors, far-end video, and assistive listening.
Check install reality
Field devices need pathways, ports, power, mounting, and service access. Long HDMI, uncounted USB, missing patch panels, and under-sized switches are common quote killers.
- Use extenders or AVoIP where table, camera, or display runs exceed practical direct-cable limits.
- Confirm USB type, speed, and active-extension needs.
- Make the riser clean enough that every path can be traced by someone who did not build it.
Common questions

What is the first step in building an AV system?
Start with room use case and signal flow. Decide what people need to see, hear, present, capture, control, and connect before choosing specific equipment.
Why does an AV riser matter?
The riser exposes how the system is physically connected. It helps reviewers catch missing extenders, wrong signal direction, missing control paths, and undercounted cables.
