The best way to reach us is by email. We read every message and use your feedback to fix errors and decide what to build next.
What to write to us about
- Report a calculator error: a result that looks wrong or a warning that misfires.
- Suggest a tool or feature: a calculator you wish existed.
- Correct a guide: a factual mistake, an unclear explanation or an out-of-date detail.
- Ask a question: about the tools, the site or your results.
Reporting a calculator problem
You will get a faster fix if you include:
- which tool you used (Microphone Finder or Amplifier Calculator);
- the values you entered, for example speaker impedance, power, sensitivity, distance and target level;
- the result you got, and the result you expected and why.
Please note
We cannot give personalised installation or repair advice, and we cannot diagnose faulty equipment by email. For safety-critical work, follow your equipment's manuals or ask a qualified installer. For how we handle your email, see the Privacy Policy.
