About Sound Tech HQ

Sound Tech HQ is a set of calculators and quick references for people who install, run and fix sound and AV systems.

It's built by an engineer with years of work in public radio broadcast and recording, live sound reinforcement, and commercial AV integration. The goal is simple: the numbers you need on a job, plus the practical notes that come from doing the work, on a page that loads fast on a phone in a ceiling.

The maths behind every tool is checked against hand-worked examples. Even so, always confirm against the manufacturer's specifications and your local electrical code before you install.
