1. Introducing SPON’s powerful IP PA Intercom System
SPON has officially launched its groundbreaking IP PA Intercom System, integrating both IP PA System and IP
Intercom System functionalities. The system comprises IP Speakers, IP Paging Microphones, IP Intercom Terminals,
Emergency Call Boxes, and management software. The all-IP design allows easy network integration for a potent
digital public address system, ensuring rapid, reliable, and secure information dissemination across LANs and the
Internet.
The IP PA System extends beyond basic broadcasting, incorporating features such as video monitoring and internal
intercom. This integration optimizes resource utilization and centralized device management.
1. Background Music
Source options include AM/FM tuners, CD/DVD/MP3 players, computers, USB drives, and networked broadcasting
hosts, delivering ambient music to various zones.
2. Daily Broadcasting:
Manual microphone broadcasts from the control room and automated system broadcasts. The IP PA intercom
system offers rich features for personalized business broadcasts.
Anytime paging: Voice broadcasts to specific areas or groups via paging microphones.
Multi-source playback: Independent control of content on each terminal or broadcast by region or group.
Offline broadcasting: Terminals automatically download scheduled broadcasts during network idle times, ensuring
uninterrupted playback even if disconnected.
TTS Voice Broadcasting: Text-to-speech function for automatic conversion and standard voice playback.
Scheduled program playback: Automated 24/7 broadcasting according to uploaded audio files and schedules.
Audio production: Free tools for recording, converting, and editing audio materials.
Permission management: Configurable user accounts with different privileges.
Real-time acquisition and broadcasting: Compression of external audio sources into high-quality data streams for
real-time playback on front-end terminals.
3. Emergency Broadcasting
Independent emergency microphone input, control, and execution. Acts as a backup in automatic, semi-automatic,
or manual broadcast failures. Prioritizes over other functions during emergencies, delivering pre -recorded fire
evacuation broadcasts or urgent announcements.
The system's main control device features a prominent red emergency button for one-touch area-wide broadcasting,
providing fire evacuation broadcasts or manual evacuation calls. Whether for routine fire drills or unforeseen
emergencies, this system ensures swift response. It can be programmed for area-wide or adjacent zone alarm
broadcasts, offering flexible usage.
4. Text-to-Speech Broadcasting
In large-scale broadcasting scenarios with diverse business requirements, traditional manual broadcasting or
program recording methods lag behind. Selecting high-quality announcers is challenging, and ensuring consistent
quality with each playback is difficult. The Text-to-Speech (TTS) digital voice synthesis system, powered by computer

2. technology, addresses this issue. Users can input text into the computer, enabling convenient and high-quality
business broadcasts. Moreover, it seamlessly facilitates multilingual conversion, offering flexibility, convenience, and
efficiency.
The IP PA intercom system integrates TTS voice synthesis technology for text-to-speech broadcasts. The
user-friendly interface allows intuitive configuration of broadcast voice type, speed, background music, and volume.
Settings can be saved as templates for easy retrieval.
TTS voice synthesis is applicable for scheduled broadcasts, real-time broadcasts, and triggered broadcasts, assisting
users in efficiently completing various broadcasting tasks. It standardizes the broadcasting effect, mitigating
variations in voice quality across different individuals.
5. Audio-Text Synchronized Broadcasting
In venues like auditoriums, theaters, and concert halls, LED screens are often used to display lyrics for audience
convenience. Movie or TV show broadcasts without subtitles may cause viewers to miss out on some exciting
dialogues. The IP PA intercom system pioneers the introduction of subtitles into public broadcasting, presenting a
novel concept of Audio-Text Synchronized Broadcasting. This approach simultaneously displays spoken content in
textual form on LED speakers or screens, achieving synchronized audio and text. Through this audio-visual
combination, audiences can better and more comprehensively receive broadcast information. Particularly beneficial
in special education schools, Audio-Text Synchronized Broadcasting aids hearing-impaired students, enabling them
to "hear" broadcasts.
6. Integrated Surveillance Broadcasting
The IP PA intercom system integrates surveillance video, allowing the system client to display external surveillance
videos in split screens and initiate broadcasts within the current image window. Through the linkage configuration
between cameras and broadcasting, it achieves the organic combination of audio and video. Real-time monitoring of
the on-site situation enables direct communication with specific broadcast areas when anomalies are detected,
enhancing management capabilities. The system supports adding IPC surveillance points, binding broadcasting to
N-to-N modes, enabling one surveillance point to link with multiple speakers and multiple surveillance points to link
with a specific speaker.
7. Visualized Management
The IP PA intercom system features a visualized software management platform with a comprehensive "one-map"
display interface. This interface provides an overview of the entire system, including terminal quantity , terminal
operational statistics, task planning quantity, media file quantity, server quantity, and more.
8. Two-Way Intercom, One-Touch Assistance
The IP PA intercom system seamlessly integrates professional intercom technology and capabilities, enabling
platform sharing and device utilization. Simply connect intercom terminals to the existing broadcasting network, and
after server authorization, they are ready for use.
Many terminals within the IP PA intercom system have intercom capabilities, including paging microphones,
network audio terminals, and even amplifiers. Users can utilize these devices for two -way communication. Intercom
terminals serve as tools for emergency communication on campus, installed in classrooms, dormitories, libraries,

3. cafeterias, etc. In cases of accidents, sudden illnesses, campus violence, etc., users can initiate real-time calls to the
security center through intercom terminals, promptly seeking assistance.
Moreover, the system can integrate with any IP intercom terminals from international communication companies,
creating a robust professional intercom communication system. IP intercom terminals also possess broadcasting
capabilities and can be used as broadcasting terminals.
9. Rich Interfaces
Integrated Interfaces
The system supports data communication with external devices. Based on specific functional requirements, custom
interface software can be designed to facilitate data communication between the IP PA intercom system and
external devices.
The system also provides a secondary development SDK, enabling integration with the user's comprehensive
management platform. This effectively allows the IP PA intercom system to work in synergy with the user's business
system, enhancing overall operational efficiency and avoiding information silos. Integration with other system
platforms enables third-party software to directly control broadcasting.
Telephone Interfaces
The system's telephone gateway offers 4 interfaces connected to PXB program-controlled telephones, with dynamic
allocation of these interfaces. Through programming within the IP PA intercom system software, permissions for
program-controlled telephone broadcasting can be easily configured. Program-controlled telephones can perform
zone-based broadcasting calls to IP terminals based on voice prompts.
Remote Control Interfaces (Optional)
The system can provide fully open and controllable remote control input/output signals (switching signals). Each
signal can be used for interconnection and interaction with other systems, given that both parties agree on
predefined definitions for interconnection. For instance, integration with video monitoring systems, access control
systems, alarm systems, etc. In video monitoring systems, users can customize alarm audio. In case of an emergency
alarm from a specific camera, the corresponding linked broadcast automatically plays the preset emergency
broadcast content.
SIP Interfaces
The system allows direct connection to third-party SIP speakers. Through the use of SIP protocol, point-to-point
broadcasting calls can be realized. Terminals within the IP PA intercom system can also directly connect to
SIP-compatible devices such as IPPBX and VoIP telephone systems.
