Terms
Short rules for a site that publishes calculations, not contracts.
Last updated 2026-08-06
Informational use
The calculator and scenarios are engineering aids based on published specifications. They are not a warranty that a purchase will suit your room, voice or mains supply, and they do not replace the manufacturer’s own documentation or a competent technician when safety is at stake.
No accounts
There is nothing to sign up for. Using the public pages does not create a contract between you and the operator beyond the ordinary rules of visiting a website.
Affiliate links
Where a shop link may earn a commission, the page says so next to the link. The calculation does not change because a link is present.
Governing details
The operator is Artem Maliuha (Sole trader (FOP) registered in Ukraine). Contact and imprint pages carry the registration details.
