Before you ask
Common questions
How many speakers and zones do I need?
Use the builder above for a starting estimate, or send a floor plan and we size the 100V lines and zone split exactly, then quote it as one BOQ.
Will it integrate with fire alarm?
Yes — priority inputs let emergency signals and live paging override background music across selected or all zones.
Do you install and commission it?
Yes. Free survey, licensed install, commissioning, AMC and spare parts — all handled locally.
Planning a project?
Share your floor plan or BOQ — our engineers size it and send one quotation with installation cost.
