AudioX — Smart IP Audio & Campus Public Address System

AudioX is a next-generation Audio over IP (AoIP) broadcasting and communication system developed by DeviceLab. It replaces cumbersome analog public address (PA) cabling with standard IP networking, streaming high-definition digital audio, automated schedules, two-way intercom, and emergency voice alerts across school campuses, regional hospitals, industrial parks, and commercial towers.

Unlike centralized analog amplifiers that push high-voltage 100V audio down miles of copper wire, AudioX operates on a distributed digital edge architecture. Audio streams are encoded digitally at the management server or paging console, transmitted across existing Cat5e/Cat6 LAN infrastructure using UDP/RTP multicast, and decoded directly at individual speaker endpoints with integrated high-efficiency Class-D amplification.

Traditional analog public address systems suffer from severe architectural limitations:

• High Cabling Costs & Signal Degradation: Requires thousands of feet of specialized high-voltage speaker cabling prone to electromagnetic hum, interference, and corrosion.
• Rigid Hardware Matrix: Partitioning zones requires physical mechanical switchboards. Reconfiguring speaker zones after construction is virtually impossible without pulling new cables.
• Single Point of Failure: A failure at the central analog amplifier rack leaves the entire building or campus completely voiceless.
• Zero Telemetry: Facility managers cannot verify whether a loudspeaker in a distant corridor is functional or disconnected until someone manually notices.

AudioX addresses every operational demand of complex modern facilities:

• Granular Multi-Zone Paging: Broadcast to a single classroom, an entire workshop hall, an outdoor sports field, or the entire campus simultaneously with one click.
• Automated Bell & Chime Scheduling: Programmable weekly calendars for school class change bells, factory shift change chimes, and pre-recorded announcements with sub-50ms synchronization.
• Remote Audio Telemetry: Real-time device heartbeat surveillance and remote acoustic monitoring allowing operators to audit audio quality from a web console.
• Two-Way SIP Intercom: Full-duplex voice communication between gate terminals, classroom intercom stations, and the security control desk.
• Emergency Broadcast Override: Direct integration with building fire alarm systems (dry contact or API) to trigger automated high-priority evacuation announcements instantly.

DeviceLab engineered the AudioX hardware terminal from the ground up for industrial continuous-duty operation:

• Dedicated Processing SoC: Dual-core processing architecture dedicated to RTP audio stream decoding, acoustic echo cancellation (AEC), and network protocol serialization.
• Integrated Class-D Amplification: Ultra-low thermal dissipation digital power amplifiers delivering 30W to 120W RMS directly into standard 8Ω or 70V/100V speakers.
• Dual Network Interfaces: 10/100 Mbps Ethernet port with optional Power-over-Ethernet (PoE+ / 802.3at) alongside 2.4GHz Wi-Fi for locations where cabling is impractical.
• Auxiliary Local Inputs: 3.5mm line input, balanced microphone port, and dry-contact alarm inputs for localized physical switches.
