Four Pillars of Public Address
From zone‑based to IP‑based, speakers to amplifiers – all designed, installed, and supported in‑house, pan‑India.
Zone‑Based Systems
Multi‑zone paging and emergency override – hospitals, factories, campuses. DSP zone routing, priority hierarchy, and fire‑alarm integration.
IP‑Based PAS (Dante / AES67)
Networked audio over Ethernet – scalable, remote management, no recabling. Ideal for multi‑building campuses and large enterprises.
Speaker Systems
Ceiling, horn, column, and line‑array speakers. Acoustic coverage design, SPL testing, and STI (speech intelligibility) measurement.
Mixers & Amplifiers
DSP, analogue mixers, and 100V line amplifiers. Rack design, wattage sizing, fire‑alarm interface, and integration with existing systems.
Why Enterprises Trust Our
PAS Engineers
Public address is not just about speakers – it's about intelligible announcements, regulatory compliance, and seamless fire‑alarm integration. We design systems that ensure your message is heard clearly and reliably in every corner of your facility.
Acoustic‑Design‑First
STI (speech intelligibility), SPL (sound pressure level), and coverage mapping are modelled before a single speaker is installed.
Zero Subcontracting
Every PAS project is delivered by our own engineers – no third‑party audio subcontractors.
Network + PAS One Team
We handle VLANs, QoS, and Dante/audio networking – no finger‑pointing between separate network and audio teams.
Vendor‑Agnostic
We work with TOA, Bosch, QSC, Crown, Yamaha – we recommend the right fit, not a forced brand.
Full Documentation
Acoustic coverage maps, wiring diagrams, system configurations, and user guides – all delivered at handover.
AMC with Acoustic Testing
Annual maintenance contracts include STI re‑testing, amplifier calibration, and 12×6 break‑fix support.
From Design to Deployment in 6 Steps
Needs & Site Assessment

Zone layout, DSP configuration, amplifier sizing, and network design (for IP‑based).
Installation & Cabling
100% in‑house team. Speaker mounting, 100V line or network cabling, and rack assembly.
Configuration & Integration
DSP tuning, fire‑alarm interface, zone logic, and network QoS (for Dante/AES67).
Testing & Handover
Speech intelligibility test, SPL measurement, fire‑override verification, and documentation.
Traditional Analogue PAS vs IP‑Based PAS – Which Architecture?
| Feature | Traditional Analogue PAS | IP‑Based PAS (Dante/AES67) |
|---|---|---|
| Scalability | Hardware‑limited (zone cards) | Unlimited (software‑defined) |
| Cabling | Dedicated 100V line speaker cabling | Standard Ethernet (Cat6/6A) + optional speaker lines |
| Remote Management | Limited / None | Centralised dashboard, monitoring |
| Zone Flexibility | Fixed zones, hardware reconfiguration | Software‑defined zones, instant changes |
| Best For | Small to medium, fixed installations | Multi‑building, campuses, large enterprises |
*Layerix recommends IP‑based PAS for new builds and multi‑site deployments; analogue for simple, fixed installations.

“Layerix designed and installed a 12‑zone PA system for our 500‑bed hospital – integrated with the fire alarm and BMS. STI testing ensured clear announcements in every ward. The team was professional and on schedule.”
Facilities Director
Multi‑specialty Hospital, Bengaluru
“We upgraded our legacy PA to IP‑based Dante across 4 factory buildings. Layerix reused existing speakers, added network interfaces, and gave us centralised control from one dashboard. No recabling, huge cost saving.”

Frequently Asked Questions
Everything you need to know about public address systems.
What is a zone in a PA system?+
A zone is a logical grouping of speakers in a PA system that can be addressed independently. For example, a hospital may have zones per floor or department – enabling announcements targeted to specific areas (e.g., 'Code Blue in Zone 3'), background music in lobbies, and emergency evacuation in all zones simultaneously.
Does the PA system need to integrate with the fire alarm?+
Yes. As per NBC (National Building Code) and local fire regulations, PA systems in commercial buildings must be integrated with the fire alarm system – ensuring emergency announcements and evacuation tones override all other audio. Layerix builds mandatory fire‑alarm integration into every deployment.
What is speech intelligibility (STI) and why does it matter?+
STI (Speech Transmission Index) measures how clearly speech is understood in a space. For emergency announcements, STI ≥ 0.7 is required by regulations. We design and test systems to meet STI standards using acoustic modelling and on‑site measurements.
What is the difference between an IP‑based PAS and a traditional analogue PAS?+
Traditional analogue PAS uses dedicated 100V line cabling with limited scalability and fixed zones. IP‑based PAS transmits audio over Ethernet using protocols like Dante or AES67 – enabling unlimited zones, remote management, seamless scaling without recabling, and integration with IT networks.
Can I upgrade my existing analogue PA system to IP‑based?+
Yes. Layerix upgrades legacy PA systems to IP‑based without replacing speakers – we add network audio interfaces, DSPs, and management software, reusing existing speaker wiring while adding modern features like remote control and zone expansion.
Do you provide AMC and calibration for PA systems?+
Yes. Our AMC contracts include speech intelligibility re‑testing, amplifier calibration, DSP firmware updates, and 12×6 break‑fix support. We also offer remote health monitoring for IP‑based systems.
