PA systems
A Public Address (PA) system is more than just a microphone and speakers—it’s a vital communication tool for safety, efficiency, and customer experience. Whether you’re running a hospital, school, retail space, or industrial site, a properly designed PA system ensures your message is delivered clearly, instantly, and everywhere it needs to be heard. Delta has supplied and installed sound and public address equipment since our inception in the 1970's and we have become experts in supplying and installing amplifiers, microphones and a selection of speakers all to suit your requirements and budget.
Why Choose a Professional PA System?
Crystal Clear Announcements – Speech and alerts are amplified so they cut through background noise.
Emergency Integration – Connects with fire alarms and security systems to broadcast urgent evacuation or safety instructions.
Zoned Messaging – Direct messages to specific areas—such as classrooms, waiting rooms, or departments—or broadcast site‑wide with a single command.
Multi‑Purpose Use – From paging staff and making public announcements to background music and promotional messaging.

The differences between 100V Line and IP‑Based PA Systems:
|
Feature / Aspect |
100V Line PA System |
IP‑Based PA System |
|---|---|---|
|
Technology |
Traditional analogue system using amplifiers and 100V line cabling to distribute audio |
Digital system using existing IP networks (Ethernet) to transmit audio data |
|
Installation |
Requires dedicated cabling to each speaker zone |
Uses existing LAN/WAN infrastructure, reducing new cabling in many cases |
|
Scalability |
Best for small to medium‑sized sites; expansion requires additional cabling and amplifiers |
Highly scalable; easy to add new zones or devices by connecting to the network |
|
Audio Quality |
Good for speech and background music; limited fidelity |
High‑quality digital audio with minimal loss, suitable for music and announcements |
|
Zoning & Control |
Fixed zones; changes require rewiring or reconfiguration |
Flexible software‑based zoning; zones can be changed or grouped instantly |
|
Integration |
Can link to fire alarm panels and basic triggers |
Integrates with fire alarms, security, VoIP phones, and other IP‑based systems |
|
Reliability |
Very robust and proven technology; minimal network dependency |
Dependent on network stability and bandwidth, but offers redundancy and monitoring |
|
Cost |
Lower upfront cost; ideal for straightforward installations |
Higher initial investment, but reduced cabling and long‑term flexibility can save costs |
|
Best Suited For |
Schools, small offices, retail, and sites with simple paging/music needs |
Hospitals, campuses, transport hubs, large enterprises, and multi‑site organisations |
How to Decide - Choose 100V Line if you need a cost‑effective, reliable system for straightforward paging and announcements. Choose IP‑Based if you want flexibility, scalability, and integration with modern IT and safety systems.
