Audio over IP · Enterprise Public Address
Smart IP Audio & Campus Public Address Systems (AudioX)
Modernize public address infrastructure with decentralized, high-fidelity Audio over IP (AoIP). Replace outdated analog 70V/100V speaker wires with standard Ethernet and Wi-Fi networks. Engineered for multi-campus universities, hospitals, manufacturing plants, and smart municipal districts.
Engagement Scenarios
When Enterprises Partner With DeviceLab For This Service
We collaborate with forward-thinking enterprises, OEMs, and product innovators navigating critical hardware challenges.
Replacing Miles of Degraded Analog Audio Cabling
Traditional 70V/100V line transformers degrade over distance, suffer from ground loops, and require costly dedicated copper wire runs across large campuses.
Multi-Zone Granular Paging & Automated Schedules
School districts, hospitals, and industrial parks needing to broadcast different audio programs or announcements to specific rooms, buildings, or outdoor zones simultaneously.
Integration with SIP Telephony & Fire Alarm Systems
Direct interoperability with enterprise IP-PBX systems (dialing a phone extension to page zones) and dry-contact inputs for automated emergency evacuation sirens.
Technical Scope
Core Engineering Capabilities & Specifications
Deep engineering competence verified by laboratory instrumentation and compliant with global manufacturing standards.
✓ Decentralized Audio over IP (AoIP) Architecture
High-fidelity audio streaming utilizing standard RTP/RTSP multicast and unicast protocols across existing corporate LAN/WAN infrastructure without dedicated audio wiring.
✓ Hardware IP Audio Decoders & Amplifiers
High-reliability terminal decoders featuring integrated high-efficiency Class-D amplifiers (30W to 200W) or line-level outputs for existing power amplifiers.
✓ Centralized Web Management Dashboard
Intuitive browser-based GUI for real-time live paging, multi-zone grouping, scheduled bell playback, background music streaming, and volume adjustments.
✓ SIP Protocol & IP-PBX Interoperability
Standard SIP 2.0 endpoint compatibility, allowing authorized personnel to initiate announcements or two-way intercom calls directly from VoIP desk phones or mobile apps.
✓ Two-Way Emergency Intercom & Priority Override
High-clarity echo-cancelled acoustic intercom terminals with SOS panic buttons and automated priority override for life-safety emergency broadcasts.
✓ Offline Autonomy & Redundancy
Terminals feature onboard non-volatile storage to store critical chime schedules and emergency alerts, executing scheduled bells even during server or network failure.
Comparative Advantage
Engineering Partnership vs. Freelancers & Generic Agencies
Commercial hardware cannot be trusted to amateur experimentation. Why B2B enterprises choose DeviceLab.
Methodology
