Built for AV professionals, not general-purpose diagrams

Visio, Lucidchart and draw.io were never designed for AV. H2R Gear is.

Real AV gear, ready to drop in

Search the community library for Blackmagic ATEMs, Yamaha consoles, PTZ cameras, Decimator converters and thousands of other items. No more rectangles labelled "Switcher".

Real ports and connectors

Each item has accurate inputs and outputs. Draw a cable from an SDI OUT to an HDMI IN and the diagram knows it needs a converter.

Auto-generated documentation

Your diagram automatically produces a patch list and packlist. Export everything to PDF, PNG or CSV for the rest of the crew.

How the AV diagram maker works

From blank canvas to documented signal flow in minutes.

1. Add your gear. Search the library for your exact equipment or build a custom item with the inputs and outputs you need. Drop items onto the canvas and move them around freely.

2. Connect with cables. Click a port, drag to another port, and a cable appears. Pick from 18+ cable types: HDMI, SDI, XLR, TRS, USB, Ethernet, DisplayPort, Optical, BNC, RCA, Dante, NDI, fibre, power and more. Each is colour-coded so the diagram stays readable.

3. Organise with zones. Mark off areas like the stage, control room, OB truck or rack location with labelled, colour-filled zones. Add text labels for crew notes.

4. Export and share. Generate a PDF or PNG of your diagram, a CSV patch list for production documentation, and a packlist for load-in day. Share a read-only link with your crew.

Who uses it

AV diagram software for every kind of production.

Live event AV

Plan festival stages, conference setups and concert rigs. Send the diagram to your riggers, sound engineers and lighting techs so everyone arrives knowing what's needed.

Broadcast and OB

Diagram OB truck wiring, studio floor plans and multi-camera shoots. Patch lists export to CSV for production paperwork.

Houses of worship

Document the permanent install so weekend volunteers can reference it. Plan weekly service signal flow without surprises.

Corporate AV integrators

Diagram boardrooms, conference rooms and presentation systems for clients. Keep a record of every install so you can replicate or troubleshoot later.

What is an AV diagram?

An AV diagram (also called an AV wiring diagram, signal flow diagram, or AV schematic) is a visual map of an audio/video system. It shows every piece of gear, the cables between them and which inputs connect to which outputs. AV diagrams are essential for planning live events, designing installations, documenting broadcast setups and onboarding new crew members.

Why AV pros need dedicated diagram software

General-purpose diagram tools like Visio, Lucidchart and draw.io can technically draw an AV setup, but they have no knowledge of cables, connectors or AV gear. You end up redrawing the same Blackmagic ATEM shape over and over, manually colour-coding cable types and rebuilding patch lists in a spreadsheet. Purpose-built AV wiring diagram software handles all of that for you.

What makes a good AV wiring diagram

  • Accurate ports — inputs and outputs match the real device, not generic boxes.
  • Colour-coded cables — at a glance you can spot the HDMI runs versus the SDI runs versus the audio lines.
  • Zones — clear areas like stage, FOH, control room or rack with labels.
  • A patch list — a CSV or table of every connection for printing, sharing or auditing.
  • A packlist — a complete inventory of what needs to be in the cases on load-in day.

AV diagram, signal flow, AV schematic. What's the difference?

In practice, these terms get used interchangeably. A signal flow diagram tends to emphasise the path of audio or video through a system, an AV schematic often implies a more technical, installer-style drawing, and an AV wiring diagram is usually the working document used by the crew on site. H2R Gear handles all three.

Free to start

H2R Gear is free to sign up. Build diagrams, generate patch lists and packlists, export to PDF and share with your team without spending anything. Paid plans add team collaboration, more plans and additional sharing options.
