Every speaker in your building. One operating system.
Music, paging, emergency voice and audio messages — running on one supervised network, controlled from one screen. WAVMerlaud knows the condition of every speaker line in your estate, and tells you before a zone goes quiet.
Most buildings run four audio systems and manage none of them.
Background music comes from one supplier. Paging runs on an amplifier in a cupboard. Emergency voice sits under the fire contract, tested annually. Announcements are made by whoever is holding the handheld mic. Four systems, four invoices, four sets of cabling — and no single person who can tell you whether the speaker above door 12 is still connected.
Nobody notices a failed speaker until the moment it was needed. That moment is usually an evacuation.
Five layers. One system.
WAVMerlaud is built the way an operating system is built — hardware at the bottom, applications at the top, and a control layer that makes everything between them somebody else's problem.
Music, paging, emergency voice and automated announcements. Add one without touching the wiring.
Zones, priorities, schedules, permissions and a full audit trail. One screen, on any device.
Every line and every endpoint checked continuously. Faults located to the zone and reported — not discovered.
Standard IP networking. Your existing infrastructure, your existing IT team.
Merlaud amplifiers and loudspeakers, built for this since 1923.
Three things no other PA system does.
It knows itself
Every speaker line is electrically supervised, continuously. Open circuits, shorts, impedance drift and offline endpoints are detected, located to the zone, and reported to the dashboard. You find out on a Tuesday morning, not during an evacuation.
Emergency voice that cannot be silenced
When a fire panel triggers, WAVMerlaud routes EN54-16 certified evacuation voice to the correct zones within seconds — automatically, without operator intervention. The right message reaches the right zones. Adjacent areas stay on normal audio. Every action is timestamped and written to the audit log. If the network fails mid-emergency, zone controllers broadcast from locally stored messages. The building does not go silent.
It thinks for itself
Audio processing is built in. Volume adjusts automatically to the time of day. Different messages play to different zones — the food court hears a safety notice, the car park hears an alert, the entrance hears nothing at all. The right audio, in the right place, without anyone managing it.
Merlaud Hardware at Changi Terminal 3. France's national rail. Indonesia's KAI.
WAVMerlaud is not a new entrant. The hardware has been operating in the world's most demanding transport and commercial environments for decades. Merlaud supplied approximately 12,000 loudspeakers to Singapore Changi Airport Terminal 3. SNCF and RATP since 1947. PT Kereta Api Indonesia since 2018. These are not case studies — they are the engineering record that backs every specification we write.
